OilPure Water Sensor

Technology Description and How It Works
The OilPure water sensor is designed to detect media (light sludge) interfaces and level of water in oil. A low-power heater is used to produce a temperature differential varies as a function of fluid thermal conductivity for level and interface measurement.

Control circuit converts the sensing element's temperature differential into an analog DC voltage signal. Dual comparison monitor the sensing element signal and activate relay alarm circuits if the signal exceeds an adjustable set point value.

         OilPure water sensor can detect free water from 5,000 ppm to 10,000 ppm in oil reservoir. These water sensors are not designed to read water content in the oil reservoir.


There are two different  water sensors available:

Total Integrated Water Dehydration System and Oil Purification System
(Excellent  for Turbine Generator in power plant)

System Operation

  1. Water sensor can detect free water from 5,000 to 10,000 ppm in oil reservoir and automatically drains free water from oil reservoir on an on-off continuous basis. If there is excessive water breakdown, water sensor will send warning alarm signal maintenance staff to take proper action. 
  2. Vacuum jet dehydrator unit continuously removes dissolved water from 10,000 ppm down to less than 100 ppm.
  3. Oil purifier unit with PurePack process (chemical treatment) to remove solid particulate down to ISO code 15/12 to 13/10 oil cleanliness and oxidation by-products , which cause high Total Acid Number (TAN) and oil deterioration.
  4. Improve RBOT (Rotating Bomb Oxidation Test, ASTM: D-2272) result.
