Dieselcraft Fluid Engineering has developed a line of sensors designed to detect water at the fuel tank bottom before it gets dispensed or for installation in water separators to alert the user to water presence. The Dieselcraft Model 06-5 and 06-6SP Sensors are a solid-state sending unit and a self-grounding stainless steel probe.
The Model 06-5 is designed specifically to detect water in diesel fuel and gasoline but also will detect water in fluids with less conductivity than water. The 06-6SP is supplied with an additional output lead to use with a PCL control to send an alarm to shut down the equipment.
The ABS electronic enclosure houses two LED lights; the green LED light indicates the sensor has power and is ready to work, while the larger red LED will come on and stay on when water is detected. The unit also incorporates an audible alarm that will sound for 5 seconds to bring attention to the water detected.
The Model FWS-HH portable water detector is a handheld unit that can be used in conjunction with the tank-dipping process. When attached to the dipping rod, no paste is needed; turn it on and dip it, and if water is at the tank bottom, the alarm sounds.
