The Well-Functioning Steam Trap

vmwnt09 beyond valves 1Steam traps are the most important link between the steam and condensate system. Malfunctioning steam traps can waste tremendous amounts of money. Here is an example: A single inverted bucket steam trap (with a one-eighth-inch orifice) blowing-thru in a 150 psi, where the steam cost is $11.00 per 1,000 lbs. of steam produced, will waste 62.49 lbs. of steam per hour and cost approximately $6,022 in fuel losses per year.

Understanding Differential Pressure Flow Transmitters

A differential pressure flow measurement system consists of a differential pressure primary flow element and a differential pressure flow transmitter.

When the flow of a fluid in a pipe passes a restriction in the piping system, the pressure in the piping system is reduced. Most differential pressure primary flow elements are designed, constructed and operated in a manner such that the flow rate is proportional to the square root of the pressure drop across the restriction. These differential pressure primary flow elements include orifice plates, Venturi tubes, elbows, flow nozzles, low loss flow tubes, single-port and multiple-port Pitot tubes, segmental wedge and V-Cone flowmeters.
