The magnetic weir meter is suitable for long-term measurement of water levels in rivers, lakes, reservoirs, dam bodies and other weirs, and is an effective monitoring device for monitoring water level and flow changes. The weir gauge uses magnetostrictive sensors for liquid level measurement. It features high resolution, good stability, reliable performance, fast response speed, linear measurement, absolute position output, non-contact continuous measurement, no wear, no need for sensor calibration or regular maintenance, RS485 digital output signal, simple and convenient installation, and long working life. Synchronously measure the temperature at the burial point
