I am presently starting up a new cogeneration plant and the customer has forgotten to install a flow transmitter on the extraction line or a indication switch on the extraction non-return valve. This makes it very difficult for us to release the desuperheater valve for control since we don't know if a steam flow is present or not (don't want to inject water in an empty pipe. The customer has purchased an anubar flowmeter but the delivery will be long. I would like to add some redundancy to the flow signal and was wondering if any of you would have experience in steam flow switch (would be the same concept as a minimum air flow switch for a BMS)
Thank you
