Hydrostatic Liquid Level Sensor for Water/Antifreeze/Silicone Oil

A hydrostatic level transmitter calculates the liquid level by measuring the static pressure exerted by the liquid on the bottom of the sensor. Its principle is simple and reliable, suitable for various media such as water, oil, and chemical liquids, and can be used in both closed and open containers.

Measurement accuracy is mainly affected by changes in liquid density, temperature, installation height, and the sensor's own accuracy. When the density is unstable, temperature compensation or a sensor with intelligent calibration can be considered.

Common signs of damage include severe zero drift, unstable output signal, and readings that remain unchanged for extended periods or fluctuate wildly. This can be determined by comparing the calibration value with the actual liquid level.
