Neptune Differential Temperature Sensors

Neptune Differential Temperature Sensors

Under some circumstances such as with water injection flow lines, leaks can be identified using the temperature difference between the surrounding seawater and the water leaking from the flowline.

The flowline water temperature is normally above ambient seawater temperature due to the high pressure pumping required.

Neptune has developed a differential temperature technique that can detect very small temperature changes. The sensors comprise fast, high precision thermistors connected through the Neptune leak detection system to the ROV umbilical for onboard display and recording.
