Steam trap instrument module

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;
• a instrument module, the instrument module including an inlet pressure transducer, arranged to detect pressure at the steam trap inlet, an outlet pressure transducer arranged to detect pressure at the steam trap outlet, a temperature transducer arranged to detect temperature within the steam trap, and an eddy current probe arranged to detect movement of the plug;
• and
• a central processing unit operatively coupled to and arranged to receive 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 process the respective outputs to thereby determine total steam flow and total condensate flow through the steam trap.
