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. “The Water Level Indicator employs a simple mechanism to detect and indicate the water level in an overhead tank or any other water container.” according to Electronics Hub.
The purpose of a water level indicator is to gauge and manage water levels in a water tank. The control panel can also be programmed to automatically turn on a water pump once levels get too low and refill the water back to the adequate level.
A water level indicator sensor, also known as a probe sensor, is what tells the control panel that corrective action is needed. A combination of high and low sensors are used to tell the control panel when water levels are too high or too low. The control panel will then automatically turn the pump on or off depending on the corrective action needed.
The working principle of a water level indicator is actually quite simple. Water level indicators work by using sensor probes to indicate water levels in a storage tank. These probes send information back to the control panel to trigger an alarm or indicator. As mentioned above, the control panel can be programmed to automatically turn on your pump to refill the water again.

    The water level is full – Nothing happens
    Water level drops to the reference probe – Alarm is triggered
    Fill start is triggered automatically turning on the water to fill the tank
    Once the water is full, fill stop is triggered and the system automatically stops the pump
    The system resets and waits for water levels to drop again

Depending on the manufacturer, some water level indicators will have 3 probes while others might have as much as 7.

3 Probe water level indicators use a reference probe, fill start probe and fill stop probe to manage water levels. These probes work together to manage the water levels in a tank. The reference is the lowest point you want the water level to go to before the water starts filling again. The fill start probe is usually the same length as the reference probe to ensure the pump starts filling the water once it has reached its lowest point.

5 probe water level indicators use more probes to also include alarms. They have the same reference probe but also come with a low alarm & high alarm probe that will tell you if water levels become too low or too high.
