Differential pressure level transmitter series DPL50 is a DP level sensor uses two pressure sensors that are linked together electrically. This system called Electrically Remote System(ERS) which is a flexible, 2-wire, 4-20 mA calculates differential pressure (DP) using the electrical communication technique between the upper and lower pressure sensors.This technique removes the headaches of using capillary and improve the performance.
DPL50 differential pressure level transmitter provide the level measurement solution where in-tank problems such as foaming, vapor and high viscosity prohibit the use of other level instrumentation.
