Penberthy's MULTIVIEW™ Magnetic Liquid Level Gages can be built to serve practically any process industry situation. From the simplest operation to the most severe, corrosive environment, Penberthy can construct a system to best suit your company’s requirements. As pioneers in magnetic gage level indication and as creators of the unique concentric magnet design, Penberthy has the expertise to know what design, specifications and options best fit any given application. Contact a Penberthy representative to discuss specific duty requirements in your operation.
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 MULTIVIEW™ gages provides a more consistent magnetic field than conventional magnet designs.
Construction Materials AvailablePenberthy offers a wide range of materials, including:
Typical Process Applications
Boiler Feedwater Tank
Liquids & Slurries
Follower Style Indicator
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
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.
MGS Switches provide non-intrusive point-level control and contain no mercury. They allow you to be environmentally safe without sacrificing accuracy.
MGS-314: SPDT 5A service
MGS-314D: DPDT 10A service
MGS-314L: SPDT 1A service used with standard MULTIVIEW?
MGS-314M: SPDT 1A service used with either TMMG (Top Mount Magnetic Gage) or MMG (Mini Magnetic Gage)
Transmitters can be added for continuous level control.
MGT Transmitters provide continuous level indication to remote locations via 4 to 20 mA loop-powered operation.
MGT-362: A reed switch based unit available in integral and remote mounting styles
MGT-362B or C: An in-tank reed switch based unit. The MGT-362B is an NPT-mounted assembly. The MGT-362C is a flange-mounted assembly. Both are available in integral or remote mounting styles.
MGT-367: A magnetostrictive transmitter available with or without Hart protocol.
