S1-200 - The “talking” water-trap!
| More
The S1-200 model is the perfect solution to water detection in fuel for low horsepower engines!

Suitable for both gasoline and diesel applications, S1-200 can help you overcome all problems related to water infestation in the fuel line, by active notification upon water intrusion, whilst providing with ergonomic ways in easily disposing of the detected water.
WWS S1-200The need for pure fuel has come to be a prerequisite for the smooth function of the increasingly developing engines. By protecting the line over which fuel runs, S1-200 is the best choice for extending the longevity of every water-sensitive unit along the fuel line, let alone the engine itself.

The Water Warning System, model S1-200, is comprised of the main unit - a water-trap with a built-in electronic circuit, sensors for detecting the presence of water, a double-signal (red and green) LED located on the upper part of the unit, as well as fuel inlet and outlet fittings. Featuring two valves, one for quick and easy extraction of the trapped water and the other for ventilation, speeding up the process of water removal when it is detected. The rest of the hardware (wiring, beeper and two metal clamps) can be found right out-of-the-box.

The System is activated when about 20% of water concentration is detected in the System’s water-trap, where water is slowly gathered at the bottom part. Automatically, the beeper sounds and the LED changes from “green” to “red”. All the user has to do is turn his engine off for a few minutes, extract the water by opening the water and ventilation valves, and continue cruising with no further problems. Additionally, thanks to the special, transparent water-trap, one is allowed to “check” on the content’s status and can therefore remove water without spilling even a drop of fuel!
