Water level indicator definition: A water level indicator is a system that relays information back to a control panel to indicate whether a body of water has a high or low water level. Some water level indicators use a combination of probe sensors or float switches to sense water levels.

What is water level indicator used for?

The water level indicator circuits are used in factories, chemical plants, and electrical substations and in other liquid storage systems. There are many possible uses for this simple system, examples include monitoring a sump pit (to control pump activation), rainfall detection, and leakage detection.

Which sensor is used to detect water level?

Hydrostatic pressure level sensors are submersible sensors used for measuring the level of liquids (including corrosive liquids) in deep tanks or water in reservoirs.
