Liquid level transmitters with a 4 to 20 milliamp current loop output signal for determining liquid depth or the fluid level by measuring the hydrostatic pressure. A 4-20mA output hydrostatic level transmitter is commonly used as part of an on-site control & monitoring system to manage quantity of liquids and ensuring minimum and maximum liquid levels are not exceeded. Select a 4 to 20 mA current output hydrostatic level sensor for controlling a pump in a borehole or managing the contents of liquid storage tanks.
