Level transmitters measure liquid height within a specified range and translate this value into a proportional 4-20 mA signal
output for interface with external devices such as an indicator, controller, PLC or telemetry device. Flowline level transmitters
and indicators are offered in general purpose, intrinsically safe or explosion proof types for use in hazardous locations. A
hazardous location is generally defined as an area where flammable gases, vapors or dusts occur in such concentrations
that they could explode. Instruments that are installed in these locations are designed and certified to be intrinsically safe or
explosion proof to ensure that they cannot cause such an explosion.
