A liquid level monitoring instrument is a specialized device used for accurately measuring and monitoring the liquid level height inside various containers.

It works based on the proportional relationship between liquid static pressure and liquid level height.

The sensor equipped with the instrument is directly inserted into the measured liquid, and the pressure generated by the liquid on the sensor diaphragm is converted into an electrical signal.

The electrical signal is transmitted through a cable to the signal processing unit, and through an internally pre-set algorithm, the height value of the current liquid level is accurately calculated based on parameters such as liquid density and gravity acceleration.
