I am looking for a flow transmitter (4-20) that I can strap on externally to a gasoline pipeline and monitor flow. 1 at each end of pipe will tell if there is a leak. Non evasive, and easy to connect, reconnect every week so I can put it on other pipelines to check for other leaks. Size application for gas distribution/refinery. Plan to hook up to PLC system long term and trend on HMI.
