2808 Absence Of Water Sensor

2808

Absence of Water Sensor

Microprocessor Controlled

Detects Absence or Presence of Liquid

Standard Sample Rate is Once Every 2.5 Minutes

Form C Relay

The GRI 2808 Absence of Water Sensor is a totally new innovative design that helps

monitor the level of water and other non flammable liquids. The GRI 2808 is submersible,

fully self-contained and responds reliably to the absence of or the presence of water. The

GRI 2808 fits a multitude of applications in a wide range of environmental landscapes.

The GRI 2808 microprocessor conducts a sample every 2.5 minutes. Optional custom

sample rates are available. Call the factory for more information.

The C-form relay gives the installer greater flexibility for triggering wireless and hardwired

communication devices.

ABSENCE OF WATER DETECTOR INSTALLING THE G.R.I. 2808: The G.R.I. Absence of Water Detector is installed by mounting the unit so that sensor probes are located at the desired fluid level position. Insertion of the 2808 into the liquid will confirm that mounting point as the minimum liquid level height. Mounting the 2808 above and out of the liquid will con2808 firm that mounting point as the maximum liquid level height.
