Product overviewGKYWG-58 magnetostrictive liquid level gauge is a remote continuous liquid level measuring instrument based on Virally effect. It is suitable for the measurement of liquid level and boundary position in open or closed containers. Magnetostrictive liquid level meter has become an ideal choice for long-distance continuous liquid level measurement instrument because of its high measurement accuracy and low maintenance rate.When the magnetostrictive liquid level gauge works, the trigger circuit of the transmitter excites a pulse current, and the current propagates along the magnetostrictive line to generate a pulse current magnetic field. A magnetic float is arranged outside the sensor measuring rod of the magnetostrictive liquid level meter, 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 magnetic ring of the float, the magnetic field around the float changes, so that the magnetostrictive line generates a torsional wave pulse at the position where the float stays. This pulse is transmitted back to the transmitter along the magnetostrictive line at a fixed speed and detected by the detection circuit. The position of the float, that is, the position of the liquid surface, can be accurately determined by calculating the time difference between the pulse current and the torsional wave pulse by the central processor. The analog-to-electrical conversion circuit of the transmitter outputs 4-20mA or RS485 MODBUS signals, so as to realize the purpose of remote transmission of liquid level signals.Product featuresMulti-function, it can measure the liquid level, boundary position, single point temperature and multi-point average temperature of the storage tank at the same time, and the optional display beside the tank can realize the display under the tank and output it to the control room.Long service life, no moving parts and less maintenance.High precision, simple operation and large measuring range.Simple installation, modular design, and the instrument has self-checking function.Low power consumption, the instrument adopts low power consumption design, and the DC 5V instrument can work normally.Chinese and English menus can be switched, intelligent menu.Mechanical circuit can realize data migration.Output signal 4~20mA/HART and RS485 MODBUS are optional, which can be used for on-site indication or remote access to PLC or DCS system.With anti-static, anti-surge, anti-interference and electromagnetic compatibility design.Protect the circuit, and the reverse connection of the power cord will not damage the circuit.There are many practical scenarios, and many parameters such as crude oil, emulsion layer, water and multipoint temperature can be measured.Installation requirements: Generally, the standard flange or thread is used to install on the tank top, and the side is vertically installed under special working conditions. In order to facilitate debugging, it is recommended to install the instrument where there is a platform.
