	We have a lube oil cooler where the hot lube oil is flowing at a pressure of about 28 barg on the shell side.The tube side contains water at around 4 barg. We are interested in detecting oil leakage in water when the tube has a small leak or it ruptures. The water is a closed loop system. Does anyone have a good experience with any simple analyzer(just a probe in the cooling water side and associated electronics instead of a full blown analysis system) Thanks, and have a happy and prosperous New Year __________________ If you don't know where you are going,you are bound to get there

	Have You Considered Agar -Water Cut analyzer You can mount the probe on downstream Side with nozzle arrangement and measure the cut water in oil Regards Jose

	That is a pretty large differential.. Why not just open a drain and take a small water sample occasionally? If there is a leak, there should be oil in the water...

	Monitor the differential pressure between the oil side and the water side, use a switch or transmitter to generate a low DP alarm. You can also monitor oil outlet flow and temperature.

	I'd use the same that's used when is any leak from lube syst.to water cooling system or backwards in car engines.-

	Add some fugitive dyes like basic / direct/ acid dyes to the oil[ minimum dosage for visible detection] and look for leaked traces in coolant water. You can also locate the leakage point in the lubrication coil. A hint learned from hydraulic flow studies. __________________ Nature is so graceful and naked. Human possession is ridiculous.
