Dear friends,

In our natural gas combined cycle power plant we use seawater as cooling water. We need a system that will detect and monitor the oil level on seawater in the intake area. I've found that GE has a system called Leakwise ID-227 and Arjay Engineering has a system called 2114-HCF. Both of them are using floating sensors but they are using different techniques for measuring.

My question is that which one of them gives more accurate results. Do you have any experiences on them and is there any other company which has a system to measure the oil level?

Thank you for your valuable helps

 

We have several 'Leakwise' units installed.

We use them for trace level detection, I cannot tell from your question, but I suspect you are looking for indication at low amounts of oil on water(?). Ours have been installed for 4-5 years, and we have had minimal problems. One word to the wise, however, do not share power supplies for more than one unit, GE may have made this clear in the installation guide(or maybe not) but it gave us trouble during initial installation.

Ours are calibrated to 2mm of light oil, and seem to hold calibration well.

Have not tried any others.
Good Luck
