First we have to know what a submersible level sensor is before getting to know its working principle. It is one of the most commonly used level sensors on the market. It is a level monitoring device that is completely immersed in a liquid and measures the liquid level, such as water, wastewater, chemicals, oils and so on.

How does a submersible level sensor work？

The submersible level transmitter senses the hydrostatic pressure at the bottom of the liquid, since the static pressure on the sensor is proportional to the height of the liquid. And then it converts the pressure to an electrical signal and sends to other instrumentation.

Examples of the most commonly used submersible type level sensors

Submersible level sensors can provide continuous liquid level in tanks, wells, reservoirs, boreholes, rivers, and others. Holykell hydrostatic level sensors can provide you with high accuracy, with small temperature drift, without being affected by temperature changes, environment changes. And they can stably work in liquids for more than 10 years though in harsh environment. What's more, the submersible level sensor price can be accepted by most people. It is really a budget-friendly option.

Trust us, Holykell, a professional sensor manufacturer of over 20 years experience, can provide you the most satisfactory level sensor.
