What is a flood alarm?

The detector provides an early warning of flood situations, such as taps being left on. The flood detector should be placed on a flat surface close to a bath, wash basin, toilet or sink, where a flood or leak is likely to occur.

What are flood sensors?

Flood sensors provide your home and property with critical protection from leaks and potential flooding sustained from interior or exterior sources, via immediate alerts that can help prevent costly water damage.

What is the flood stage of a river?

A flood stage is the water level at which some type of physical or economic hardship occurs along a river. It does not necessarily mean that water is over the banks of the river. Flood stages are established by the National Weather Service based on input from the community and local emergency managers.

What is the principle of water level indicator alarm?

Principle of Water Level Indicator. 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.
