The SWLS is designed specifically for monitoring water level and water temperature in a wide range of outdoor and aquatic environments.

MiniOFS Optical Fog Sensor

Reliable Monitoring for water environments

The SWLS is designed specifically for monitoring water level and water temperature in a wide range of outdoor and aquatic environments.

Submersible water level measurement with water temperature sensor used to monitor the water level and temperature of ground and surface water, dams, lakes, pools, aquatic ponds and more.

The sensing device is potted in a stainless-steel probe and coated with a sealant to withstand outdoor moisture. It is designed specifically to monitor water level/temperature. This sensor can be connected to data-logger, controller or to some display by means of electronic interface.

If the level/temperature gets too high or low, the controller can then take the appropriate programmed action. The level/temperature can also be displayed on the console, in PC Access etc.
