NivoPress NP Hydrostatic level transmitter. General This two-wire level transmitter consists of a probe and a special, breathing cable containing a capillary pipe and a stress resistant inlet. The probe is a stainless steel cartridge with a membrane at the bottom. Level metering is based on a measurement of the pressure difference between the hydrostatic pressure of the liquid head above the probe and the actual atmospheric pressure. This difference is converted into a 4 to 20 mA output signal. Application The NivoPress NPK submersible hydrostatic level transmitter is applicable to clean or chemically faintly contaminated liquids in boreholes, open reservoirs and tanks. It is easy to install in already existing facilities and is especially recommended for monitoring and controlling of submersible pumps.
