Hydrostatic level sensor with a 4-20mA output for screw on thread mounting and measuring the level of ink in a 12 foot high tank. This version of the DMK331 has a PVDF process connector, ceramic diaphragm and FKM seal wetted components for compatibility with ink. The level of the ink is determined by measuring the hydrostatic pressure of the liquid head of ink above the sensor which is proportional to the level of ink in the tank.
