Specificity Results:
Manufacturer and evaluator claim sensors will respond to any liquid after its threshold is exceeded. 

Testing was specifically conducted for performance in water and water with a thin layer of fuel.

 

Manufacturer’s Specifications:
Can be installed on any control device that accepts TS232 communication from the sensor.

Models EOS100 and EOS120 sensors identify liquid in a range from nominal depth of 0.5 inch to 3.5 inches at 0.75 inch increments.

The Model EOS120 sensor is designed to be a drop-in replacement for the Model EOS100 sensor.

Comments:
*The position of the Model EOS80 sensor can be adjusted for any depth of liquid required.
