Swimming Pool Level Sensor

The 4174 liquid level sensor has been installed into a large swimming pool at a military base in Hawaii, to provide continuous measurement of water level.

Out in the tropical heat of Hawaii, maintaining consistent levels in large swimming pools is extremely challenging. A Military organisation has installed Gill’s liquid level sensor where the sensor accurately measures the level of the water in the pool on a continuous basis.

The 4174 level sensor is part of a closed loop, min/max monitoring system which identifies when water drops below the correct level. If the pool water is reported as being too low then the system activates a valve to add more water.

“The Gill level sensor is very critical to the system. It tells the system what mode the pool is in, when the valves need to move and when to turn on the pumps” says Carrie Carhart from Dynatak, a Gill distributor. “The level sensor was chosen for the application due to its solid-state construction, which for the technicians, no moving parts equals high reliability of this critical data.”

Previously, monitoring the pool level was a manual job which could not be carried out around the clock. Installing the new monitoring system, including the water level sensor, has removed the labour hours previously required and now allows 24 hour automated monitoring of the pool level.

The Industrial liquid level sensor was supplied with a 4-20mA output and GSlevel configuration software.
