  • Contrec 515 Series with HC12 application measures the volume, mass and energy content of the fluid in a heating or cooling system by using an analogue mass flow input in conjunction with analogue supply and return temperature inputs.

    A selection of fluid types and modes makes it suitable for many heating/cooling applications. The flowmeter input signal can be selected as either 0-5V, 1-5Vor 4-20mA. Minimum and maximum points are programmed and non-linear correction points can be used to better reflect the flowmeters behaviour.

    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.
