Steam energy metering using a standard analogue volumetric flowmeter, vortex or turbine style, still needs mass flow and energy worked out correctly, not just a raw flow reading. The Contrec 515 SC02 Steam Flow Computer, Analogue Input, is built for this.
It combines the analogue volume flow input with pressure and/or temperature sensors, and calculates mass flowrate and total energy content per the IAPWS-IF97 Industrial Formulation. Stacked analogue flow inputs and multi-point non-linear correction let it handle a wide range of flow conditions while keeping low-flow precision.
In actual application, this unit usually sits out on process plant rather than in a control room, so it comes in a weatherproof IP65 housing with a backlit alphanumeric display and a keypad. It also has an adjustable 8-24V DC sensor supply and isolated 4-20mA loop retransmission for integration into plant systems.
Before we quote this, we would normally check your flowmeter’s analogue output signal, your steam pressure and temperature, and whether you need pressure, temperature, or both as compensation inputs.
Hope this helps.
