Magnetostrictive liquid level meter
Date:2015-05-06
Summary
Magnetostrictive liquid level gauge is a high precision liquid level continuous measurement, using the principle of magnetostriction, real-time detection of surface and the interface height and has the advantages of high measuring precision, fast response time, good reliability, installation, maintenance is convenient wait for a characteristic, widely used in petroleum, chemical industry, food, pharmaceutical and other fields.

Working principle
Magnetostrictive liquid level gauge structure is shown in the following diagram. During the measurement, the circuit unit generates a current pulse, which is transmitted along the waveguide and generates a circular magnetic field. The outer tube is equipped with float, float with the liquid level change and move up and down along the outer pipe. The float is provided with a plurality of permanent magnets, so float also generates a fixed magnetic field. When meet current magnetic field and float magnetic field, resulting in a "twist" or "return" pulse, pulse. Sensor will detect the "return" of the pulse, according to the current pulse and "return" the time between pulses, by microcomputer to calculate the float of the actual position, thereby measuring the liquid level or level.
