Water and Water under Oil

The Series 100 Electronic Water Detector is designed to detect water beneath all fuel oils in storage tanks. The Series 100 is ATEX approved, fully portable and comes with 16 m cable fitted.

The Series 100 Electronic Water Detector has been designed to detect and measure the depth of water accumulating beneath Furnace Fuel Oil and Diesel in storage tanks and other containers. Operating on the conductivity principle, the control unit box contains the battery, the electronic circuit and sounder. The probe and its cable are connected to the box via a connector located on the uppermost surface of the box.

A power switch is not required as no current is drawn from the battery when probe is clear of a conductive fluid. There are no hazardous voltages at the probe and current is limited to safe levels. In use, the cable is unwound from the box handle and the probe lowered into the tank or container. Should be probe come into contact with water, a clear audible tone will be emitted from the sounder. If the probe is allowed to rest on the bottom of the tank, and then slowly raised until the alarm ceases, an indication of the depth of water below the fuel may be gauged by the amount of cable withdrawn from the tank. Applications include fuel storage tanks, ship fuel tanks and any other fuel based storage a risk from water ingress.
