  • Contrec 515 Series with HC04 application measures the volume, mass and energy content of the fluid in a heating or cooling system by using single or stacked differential pressure flow inputs in conjunction with feed and return temperature inputs.

    A selection of fluid types and modes makes it suitable for many heating/cooling applications. Flow is calculated according to equations for ISO 5167 or V-Cone meters and accurately accounts for thermal expansion.

    The instrument calculations are based on the IAPWS Industrial Formulation (1997) for the thermodynamic properties of steam. The temperature values are used to determine the density and specific enthalpy. The instrument also calculates the isentropic exponent and absolute viscosity which are required for the differential pressure calculations.

    • Suited for heating and/or cooling operation
    • Uses IAPWS-IF97 to determine water properties
    • Tailored for differential pressure meters with single or stacked transmitters
