Frequently Asked Questions (FAQs)
1. What is liquid level sensor?
Liquid level sensors, also called liquid level switches, are designed to change state when immersed in a liquid. They are used to determine if a liquid or oil exists at a particular level in a container.
2. Where are liquid level sensors used?
The uses of water level sensors include the following applications:. Water level measurement of pools and water tanks.Water level measurement of rivers and lakes.Marine level measurement.Level measurement of acid-base liquids.Oil level measurement of oil trucks and mailboxes.Swimming pool water level control.
3. How does a liquid level indicator work?
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.
