Contrec 515 Series with HC03 application measures the volume, mass and energy content of the fluid in a heating or cooling system by using single or stacked differential pressure mass flow inputs in conjunction with supply and return temperature inputs.
A selection of fluid types and modes makes it suitable for many heating/cooling applications. The instrument calculates the flow according to generic differential pressure equations and incorporates the conditions at which the flowmeter was calibrated.
The instrument calculates the mass flow and energy according to the IAPWS Industrial Formulation (1997) when the fluid type is water, while internal enthalpy and density tables are used for the selection of other industrial fluids.
