Hydrostatic Head

One of the oldest and most common methods of measuring liquid level is to measure the pressure exerted by a column (or head) of liquid in the vessel. We offer solutions with submersible sensors and through the tank wall sensor options.

400 series

The 400 series of submersible pressure transmitters includes a number of completely submersible pressure-sensing transmitter models ranging from 0 to 1m water column to 0 to 500m, that contain an air vent tube for providing a pressure differential relationship between the hydrostatic head and the atmosphere. The transducer contains associated electronic circuitry for providing an analogue output, has an IP 68 protection rating, and requires a 24 Vdc ± 10% Power Supply
One of the regular applications for these transmitters is tank level monitoring & control
