Abstract:
A steam trap system comprising:a steam trap, the steam trap including an inlet, an outlet, and a float, the inlet and the outlet separated by an orifice, the steam trap further including a plug operatively coupled to the float, the plug disposed adjacent the orifice and arranged to open and close the orifice in response to movement of the float; an instrument module mounted to the steam trap, the instrument module including a central processing unit operatively coupled to each of an inlet pressure transducer, an outlet pressure transducer, a temperature transducer, and an eddy current probe; the inlet pressure transducer positioned to detect pressure at the steam trap inlet; the outlet pressure transducer positioned to detect pressure at the steam trap outlet; the temperature transducer positioned to detect temperature within the steam trap; the eddy current probe positioned to detect movement of the plug; and the central processing unit receiving an output from each of the inlet pressure transducer, the outlet pressure transducer, the temperature transducer, and the eddy current probe, the central processing unit arranged to determine total steam flow and total condensate flow through the steam trap.
