Description:
ZERM magnetostrictive Liquid Level Transmitter is a contactless liquids level sensor designed for accurate absolute level measurement of liquids.
It can monitor the actual fluid level and temperature at the same time. Using excellent communication for monitoring and programming by EIA-RS485, data could be remote. The design and durability of the sensor make it ideal for measuring fluid levels of petroleum. The transducer provides analog output of voltage and current and digital output of Modbus. By utilizing the integral digital temperature sensor in probe, the fluid temperature could be measured as well as the level.
