1、 Product Overview
GKYWG-58Magnetostrictive liquid level meterIt is a remote continuous measurement liquid level instrument designed based on the Villarreal effect. Suitable for measuring liquid levels or boundaries in open or closed containers. Due to its high measurement accuracy and low maintenance rate, magnetostrictive level gauges have become an ideal choice for remote continuous measurement of liquid levels.
　Magnetostrictive liquid level meterThe product structure is reasonable, with high precision and low maintenance rate. This product has been widely used in liquid level measurement and process control in industries such as petroleum, chemical, power, metallurgy, food, pharmaceuticals, papermaking, water treatment, etc.

Classification of magnetostrictive level gauges:

Economic magnetostrictive level gauge

High precision magnetostrictive level gauge

High voltage magnetostrictive level gauge

(4-20mA signal) magnetostrictive level gauge

Bus 485 type magnetostrictive liquid level gauge

Optional power supply magnetostrictive level gauge

Dual power supply magnetostrictive liquid level gauge

2、 Measurement principle

When the magnetostrictive level gauge is working, the trigger circuit of the transmitter excites a pulse current, which propagates along the magnetostrictive line to generate a pulse current magnetic field. A magnetic float is installed outside the measuring rod of the magnetostrictive liquid level gauge, and the float moves along the measuring rod with the change of liquid level. A magnetic ring is installed inside the float. When the pulse current magnetic field meets the magnetic field of the float magnetic ring, the magnetic field around the float changes, causing the magnetostrictive wire to generate a torsional wave pulse at the position where the float stays. This pulse is transmitted back to the transmitter at a fixed speed along the magnetostrictive wire and detected by the detection circuit. The position of the float, i.e. the liquid level, can be accurately determined by calculating the time difference between the pulse current and the torsional wave pulse through the * processor. The transmitter analog-to-digital conversion circuit outputs 4-20mA signals or RS485 MODBUS signals to achieve remote transmission of liquid level signals.
