Penberthy Magnetic Liquid Level Gages (Pentair)










Penberthy MULTIVIEW™ Magnetic Liquid Level Gages utilize a communicating chamber constructed of 2-1/2" pipe which is connected to the process tank with either side or end connections. A float with a self-enclosed magnet is custom sized and weighted to float at the surface of the process liquid to be monitored. The float is then installed in the communicating chamber.
The industry-unique concentric magnet in Penberthy MULTIVIEW™ gages provides a more consistent magnetic field than conventional magnet designs.

Follower Style Indicator by Penberthy

In MG Follower-Type models, the unit consists of a hermetically-sealed tube in a protective view housing. Within this tube is a gold anodized aluminum follower which will mirror level changes in the process tank. This entire assembly is attached to the communicating chamber where the follower is magnetically coupled with the float. Because the follower and float are magnetically linked, liquid level changes in the process tank will cause both float and follower to rise and fall in unison. The result is a precise indication of the liquid level within the vessel.

Flag Style Indicator by Penberthy

MG Flag-Type monitors provide a more secure link between the indicator and float. The view housing is sealed and consists of a single column assembly of aluminum flags within an extruded aluminum channel. These flags are anodized with black on one side and gold on the other. Each flag houses a small magnet and is assembled on a single, individual axle. As the float in the communicating chamber rises and falls, the magnetic interaction between float and flag magnets cause the flags to rotate 180°. These changes are shown through contrasting colors – black above and gold below the liquid level.  To insure trouble-free operation, Penberthy's flags are magnetically interlocked and utilize mechanical stops. This prevents over-rotation. Penberthy's redundant axle system prevents binding, with each flag allowed to rotate on the axle and each axle free to rotate in the channel. This method of indication is always accurate, regardless of the speed of process level change or vibration.

The Penberthy MULTIVIEWTM unit consists of three major sections:

Communicating Chamber
The standard chamber consists of 2 1⁄2" Schedule 10 or Schedule 40 pipe constructed of 304/304L STS, 316/316L STS, Alloy 20®, Monel®, Hastelloy C®, PVC, CPVC, PVDF or Halar® lined. Other chamber materials such as Inconel® 625 and Titanium may also be used.

Float
The float is constructed of 316L STS, Titanium, Alloy 20®, Monel®, Hastelloy C®, PVC, CPVC, PVDF or Halar® coated. It is specifically weighted for the specific gravity of the process media.

Indicator
You have three indicator options available. The type you receive was determined at the time of purchase.

A. Follower style with stainless steel housing. This indicator consists of a hermetically sealed borosilicate tube contained in stainless steel housing. A gold colored follower is located inside the tube.
The scale assembly is an integral part of the stainless steel housing. The scale can be specified to indicate any unit of measure.
B. Follower style with extruded aluminum housing
This indicator consists of a hermetically sealed borosilicate tube contained in extruded aluminum housing. A gold colored follower is located inside the tube.
The scale assembly is a separate aluminum extrusion attached to the indicator. It is possible to receive an indicator with no scale attached. If a scale is specified, it can indicate any unit of measure and be mounted on either side of the indicator.

C. Flag style
This indicator consists of a series of magnetically interlocked flags. The flags are black on one side and gold colored on the other. As the float rises the flags rotate, turning from black to gold. The flag assembly is sealed within extruded aluminum housing.
The scale assembly is a separate aluminum extrusion attached to the indicator. It is possible to receive an indicator with no scale attached. If a scale is specified, it can indicate any unit of measure and be mounted on either side of the indicator.








Basic Mag Gage Installation Instructions

2.1 General Length:  







Minimum is 20 7/16th inches and maximum is 258 inches overall, centers are 4.25 min and 236 max.


3.1 Unpacking
Upon receipt of your Penberthy MULTIVIEWTM unit, check all components carefully for damage incurred in shipping. If damage is evident or suspected, do not attempt installation. Notify the carrier immediately and request a damage inspection. Check each item against the packing list.
The float is not in the communicating chamber when shipped. Make sure that you do not throw the float away with the packing materials. The float should not be installed until the communicating chamber has been mounted to the process vessel.
To install the float, remove the bottom flange from the communicating chamber. Insert the float top first. That end of the float has been identified with a piece of removable orange tape and the word "top" etched into the float. Place the gasket over the spring on the bottom flange and reinstall.

3.2 Mounting
1. To operate properly, the magnetic liquid level meter must be vertical.
2. Check the vessel connections with a plumb line to verify alignment. The vessel must be free from dirt and debris to avoid malfunction of the level indicator.
3. A minimum distance of 8" (203 mm) should be maintained from the centerline of the communicating chamber to the nearest source of ferromagnetic material.
4. Special handling and installation precautions must be used with long magnetic level gages. This applies to any magnetic gage 10 feet (3 meters) or more in length. Do not attempt to handle or move with single point suspension or by both end suspension (such as two people picking up a gage by the ends). The standpipe must be supported along its entire length.

"Whipping" is highly probable unless the standpipe is supported along its entire length during handling/installation. Raising a long standpipe from the horizontal (shipping) to vertical (installation) plane will cause elastic bending unless additional support is provided.




Typical damages to the visual indicators caused by mishandling
Follower style The glass tube can be stressed beyond its tensional limits and break or shatter if the standpipe is allowed to whip or bend.
Flag style The component parts of this indicator have close tolerances. If the standpipe is allowed to whip or bend during handling and/or installation, there is an extremely high probability that certain flags will 'hang up' (not rotate properly) thereby providing incorrect indication.

5. PVC, CPVC & PVDF magnetic liquid level meters are shipped without the indicator attached. This is done to prevent damage to the indicator. DO NOT attempt to install the communicating chamber with the indicator attached.

6. It is strongly recommended that shutoff devices (gagecocks, sliders, cocks) be installed between the vessel and the communicating chamber to allow the magnetic gage to be isolated for cleaning.
7. Before start-up verify that the communicating chamber is free of any particles.

3.3 Indicator Alignment
To change the direction the indicator is facing, loosen the clamps holding the indicating to the communicating chamber, rotate the indicator to the position desired, and tighten the clamps. To align the indicator use the following procedure:
Follower Style
1. Loosen the clamps holding the indicator to the communicating chamber. Move the indicator down as far as it will go.
2. Lower the liquid level in the communicating chamber until: a. Side Connection
the liquid is at the bottom feed level. b. End Connection
the indicator stops moving. Then add liquid to the chamber until the float just becomes buoyant (the indicator will start to move upward).
3. Move the indicator so that the centerline on the magnetic follower is aligned with "zero" on the calibrated scale. If you do not have a scale the bottom of the follower should just touch the cushion in the bottom of the hermetically sealed tube.
4. Tighten the clamps.
Flag Style
1. Loosen the clamps holding the indicator to the communicating chamber. Move the indicator down as far as it will go.
2. Lower the liquid level in the communicating chamber until: a. Side Connection
the liquid is at the bottom feed level. b. End Connection
the indicator stops moving. Then add liquid to the chamber until the float just becomes buoyant (the indicator will start to move upward).
3. Move the indicator until the last visible gold flag has rotated to black. This will be the third flag from the bottom. (two flags are hidden behind the nameplate) Be careful not to raise the indicator too far.
4. Tighten the clamps.

4.0 Start-Up


1. Check the connections between the communicating chamber and the vessel to insure proper mating.
2. Close the drain plug (or drain cock if applicable).
3. Open the shut off valve at the top connection.
4. Slowly open the shutoff valve at the bottom connection to allow for a gradual equalization of level in the communicating chamber.
5. Check for any leaks at the connections. If none are observed, the unit is ready for use.






5.0 Periodic Maintenance
Your Penberthy Magnetic Level Meter is designed to give you years of reliable service. However, equipment failure can occur. Sound maintenance practices require periodic inspection of the gage to ensure it is in good working order.
The end user must determine the appropriate maintenance schedule based upon his or her experience for the specific application. Realistic maintenance schedules can only be determined with full knowledge of the services and applications involved.

Do not proceed with any maintenance if the magnetic gage is still at operating pressure or temperature. Relieve the unit of pressure or vacuum, allow it to reach ambient temperature, and purge or drain it of all fluids. Failure to follow instructions could result in severe personal injury or property damage.

If the process liquid is dirty or contains deposits, it is recommended to flush the instrument periodically.
To flush the communicating chamber, close the shutoff valves, open the drain plug (or drain cock), and flush. If the float requires cleaning, the bottom flange must be removed after the shutoff devices are closed.

Verbatim LED lights





The next generation of high-efficiency, cost-saving lighting has arrived in the form of LED lighting technology. While the LED itself was first discovered almost a century ago, with the first practical devices being developed in the early 1960’s in the United States, this technology has now been applied to creating the white light needed for general use in the form of LED lighting.
LED bulbs and LED lighting fixtures combine the use of phosphor materials that transform the monochromatic light from a blue or near-UV LED to broad-spectrum white light, with electrical circuits to drive the LEDs, an optical lens to extract and focuse the light, and heatsinks to maintain the LED lamp’s optimum operating temperature.
Verbatim’s first LED lighting products come in the form of retrofit LED bulbs that are available to replace most incandescent and CFL bulbs. The efficiency of an LED lamp is approximately five times that of a standard incandescent bulb, allowing for its initial price point to be more than recovered through lower energy usage and a much longer life span. Also, LED bulbs lessen the need for power generation and do not contain hazardous materials such as mercury.

Penberthy Jets/Eductor styles

Anderson-Bolds sells Penberthy Eductors / JET PUMPS



Cross Reference between Penberthy and Jacoby Eductors.


Providing a practical alternative to more complicated and expensive methods, Penberthy jet pumps offer simple, more cost-effective ways to pump, mix or heat a wide range of liquids and gases used in the process industry. Jet pumps can operate with a wide variety of motive liquids and gases. If you recognize any of the following, you can probably use a Penberthy jet pump.

Injectors • Exhausters • Ejectors • Siphons
• Eductors • Boosters • Kinematic Pumps




Penberthy jet pumps have a myriad of uses. Jet pumps not only pump liquids, they can also heat, mix, and blend either in-line or in a tank. Jet pumps can evacuate gases, create a vacuum, boost suction pressures, mix granular solids with liquids and move granular solids with compressed air. In fact, you will be surprised at what a jet pump can do to solve your problem.

Penberthy Model TMEJacoby Model TLM 

Liquid Motive Eductors are the LL, LM and LH models.
Water is the usual liquid motive.

LL series - 15-200 psig (100-1380 kPag) - Head pressure to to 50 ft. (15.2 m)–H2O


LH series - 15-200 psig (100-1380 kPag) - Head pressure 40 to 80 ft. (12.2-24.4 m)–H2O


LH series - 15-200 psig (100-1380 kPag) - Head pressure 80 ft. (24.4 m) or more–H2O

Gas or Steam motive Eductors are the GL and GH models.
Another method of pumping liquids is to use steam as the motive. This type of jet pump works best
in applications where a minimal amount of infusion of the motive media with the liquid to be transported is required. Quiet operating steam motive jet pumps, like liquid motive pumps, are simply designed with no packing glands and no moving parts to wear out.

GL model eductor 
Motive steam pressure to elevate liquid 50 ft. (15.2 m)
150 psig (1035 kPag)

Motive steam pressure range :  60-150 psig

Suction lift–water temp. to 120° F (49° C) : up to 20 ft. (6.1m)


Minimum NPSH : 13 ft. (4 m)




GL model eductor 
Motive steam pressure to elevate liquid 50 ft. (15.2 m)
75 psig (520 kPag)
Motive steam pressure range :  35-150 psig

Suction lift–water temp. to 120° F (49° C) : up to 20 ft. (6.1m)


Minimum NPSH : 13 ft. (4 m)

Penberthy Models LM, ELL and FL are perfect for many gas pumping operations where more costly and complicated pumps have been used. Imagine being able to use a jet pump to: create a vacuum, evacuate gases from tanks and vessels, scrub a gas to remove contaminants, remove fumes, for gas condensation, drying, distillation, deaeration and more.

Model ELL 
Motive medium pressure range : 20-200 psig

suction range  1-27 inches Hg


Penberthy circulating tank eductors, also known as in-tank mixers, may provide a low cost alternative over other mechanical methods. These units promote more thorough mixing action than either mechanical mixing or air sparging. The flow pattern is easily controlled and provides more complete integration of substances in a wide variety of viscosities and liquids. Penberthy in-tank mixers are inherently non- clogging, and with no moving parts require little or no maintenance. Slurries containing abrasive solids can wear out mechanical mixer blades, involving constant maintenance and process down time.

CTE - Circulating Tank Eductor
Pressure differential of inlet to tank pressure - 10-100 psig (70-690 kPag)
Mixing ratio : 3:1
Max. operating liquid viscosity: up to 2,000 cPs

Controlled Energy and Bosch Tankless Heaters - CEC

Controlled Energy Corporation - CEC
Controlled Energy Corp., 340 Mad River Park, Waitsfield, VT 05673




Controlled Energy was a tankless water heater pioneering company bringing the tankless technology to the USA.  From their Vermont mountain location, CEC distributed their Tankless Heaters throughout the USA through reps and distributors.  In about 2004 CEC closed down. Anderson-Bolds was the Ohio CEC rep.

CEC bought heaters from Bosch, Takagi, Ariston, Red Wing, Eemax and others.  They named their gas heaters AquaStars and the Electric heaters were called PowerStars and PowerStreams.

AQUA STAR Models were AQ 38B, AQ 125, AQ 125B, AQ 125X, AQ 125HX, 125FX, 240FX, 250SX

Spare and repair Parts for some of these heaters can be purchased HERE.

The PowerStar Heaters were electric point of use and whole house heaters.  

These are the Power Stream heaters and they are still available:
RP1  9.5 kw, 220/240 volts  40 amps
RP2  6.0 kw, 277 volts  22 amps
RP3  3.2 kw, 120 volts  30 amps
RP7  7.2 kw, 220/240 volts  30 amps
RP9  9.5 kw, 277 volts  35 amps
RP12  12kw, 220/240 volts  50 amps

They became know as the AE3.4 (RP3), AE7.2 (RP7), AE9.5 (RP1) and AE12 (RP12).  

Their are two Power Star models.

AE115   17kw, 220/240 volts  80 amps

The AE115 is normally used in the southern part of the country where ground water is always above 60 degrees F year round.  The heater requires 2 x 40 amp double breakers.  It has an adjustment knob to limit the outlet temperature.  Only one shower should be operated at a time.  Homes with two showers should take turns.  Flow rate of the water is the determining factor of the outlet temperature.  the higher the flow rate the lower the outlet temperature.  At a flow rate of 2.5 gallons per minute the heater with change or raise the water temperature about 45 degrees.  A 150 amp panel minimum is required for installation.


AE125   27kw, 220/240 volts  120 amps

The AE115 can be used throughout the country.  The heater requires 3 x 40 amp double breakers.  It has an adjustment knob to limit the outlet temperature.  Only one shower should be operated at a time.  Homes with two showers should take turns. If the ground water is above 70, two showers may possible be used simultaneously.  Flow rate of the water is the determining factor of the outlet temperature.  the higher the flow rate the lower the outlet temperature.  At a flow rate of 2.5 gallons per minute the heater with change or raise the water temperature about 65 degrees.  A 200 amp panel minimum is required for installation.

The Gas AquaStar heaters are now all made by Bosch Thermotechnology.



Most of the "retail" heaters are no longer manufactured.  
You can try GPTS to see of any are still available.

Bosch makes these now for wholesalers and they need to be properly installed.
The most critical component to a gas tankless water heaters is proper installation.
Tankless heaters are NOT drop in replacements for Tank heaters.  The heaters below range fro 74,000 BTU to 225,000 BTU with Stainless Steel vent, PVC vent, B-Vent vent, and outdoor units that do not require a vent.  Go here for your Z-Flex Stainless Steel vent needs.
