Magnetostrictive liquid level meter is a high-precision liquid level measurement instrument that uses magnetostrictive effect to achieve non-contact liquid level detection, suitable for complex working conditions in the industrial field. The following are its core functions and features:
1. High-precision continuous measurement
Through the interaction between the magnetostrictive waveguide wire and the float magnetic ring, the propagation time difference of the ultrasonic pulse is measured to achieve continuous monitoring of the liquid level and interface, with an accuracy of up to ±0.5mm, which is suitable for processes that require precise control (such as chemical raw material tanks).
2. Multi-function integration
Multi-parameter output: can simultaneously measure liquid level, interface (such as oil-water separation), and temperature (integrated PT100 sensor).
Signal output: supports 4-20mA, HART or digital communication (such as Modbus), which is easy to access the automation system.
3. Resistant to harsh environments
Adopting a fully sealed structure, it is resistant to high pressure (up to 40MPa), high temperature (-196℃~+200℃) and corrosive media, and is suitable for oil storage tanks, LNG equipment, etc.
4. No mechanical wear and low maintenance
Non-contact measurement avoids mechanical loss, has a long life, only requires regular calibration, and has low maintenance costs.
5. Safety and explosion-proof design
Passed ATEX, IECEx and other explosion-proof certifications, suitable for flammable and explosive environments (such as refineries and chemical plants).
Typical application scenarios:
Petroleum/chemical tank level monitoring
Sanitary level measurement in the food and pharmaceutical industry
Ship ballast tank or sewage treatment interface detection
