Magnetostrictive level gauge

Magnetostrictive level gauge is a highly accurate measuring instrument that can perform continuous liquid level and interface measurement, and provide analog signal output for monitoring and control. This product can replace the electric float level gauge in all aspects. Without a mechanical transmission mechanism, the reliability is significantly higher than that of an electric float. Not affected by changes in medium density and temperature, reflecting the true liquid level, with much higher accuracy than the electric float. Installation and calibration do not require liquid level adjustment, which is much more time-saving and labor-saving than electric floats. The price is comparable to or lower than the electric float, and it is easy to replace it with a magnetostrictive level gauge at the original installation position of the float.

1、 Application scope:
1. Various types of tank farms, storage tanks, and gas stations.
2. Oil water interface and other interfaces.
3. Liquid level monitoring in production processes such as petroleum, chemical, metallurgical, power, light industry, pharmaceuticals, and food.
4. Environmental protection, sewage treatment, and municipal engineering.
2、 Product composition:
The basic structure includes electronic conversion components equipped with signal processing and inductive electronic components installed in stainless steel tubes or non-magnetic material tubes.
3、 Working principle:
The magnetostrictive level gauge consists of three parts: a measuring tube, a float, and an electronic transmitter. The outer tube of the measuring tube is a stainless steel protective tube, and the inner tube is a magnetostrictive wire; The float rises or falls along the measuring tube with the liquid level, and is equipped with a permanent magnet inside, forming a magnetic field around it; The electronic transmitter emits a timed current pulse, known as the starting pulse, which propagates downwards along the magnetostrictive line and generates a magnetic field around it during its downward movement. At the moment when two magnetic fields meet, a torque is generated, which acts on the magnetostrictive line and forms a return pulse. The pulse propagates upwards at a fixed speed and is received by an electronic transmitter. The liquid level height can be accurately measured by measuring the time interval between the starting pulse and the returning pulse.
4、 Product features:
1. High stability, high reliability, and high precision. No mechanical force transmission mechanism, unaffected by changes in medium density and temperature, reflecting the true liquid level.
2. It can measure liquid level, interface, temperature, and density.
3. Anti corrosion, explosion-proof, long-lasting, maintenance free, and low operating costs.
4. Easy installation and simple calibration (button operation, no need for liquid level adjustment).
