Project Description

RS485 High Accurate Fuel/Diesel Magnetostrictive Level Sensor

Product Type

Anticorrosion magnetostrictive linear level transducer,
Flexible magnetostrictive linear level transducer,
Magnetostrictive linear level transducer, (hard tube) (oil and chemical).


Our magnetostrictive linear level transducer 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.


  • High accuracy to meet the high requirements metering of tank level measurement occasions

  • Stable performance, without affect of temperature and pressure changes of gas and liquid inside the tank

  • Various output options to meet a variety of collection system requirements

  • Intrinsic Safety Certification:ExiaIIBT5 to adapt to a variety of safe applications

  • Modbus, which can measure various parameters of liquid level, interface, temperature

  • Various anti-corrosive structure, to meet a wide range of oil, chlorine and other corrosive measurement environment

  • Easy installation, no maintenance.
