  • Contrec 515 Series with HC02 application measures the volume, mass and energy content of the fluid in a heating or cooling systems by using analogue volume flow input in conjunction with an analogue feed 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, 1-5V or 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.

    CALCULATIONS

    The instrument can calculate the mass and energy for the following common industry fluids:

    Water
    Glycol (35% Solution)
    Brine (27% CaC2)
    TYFOXIT F20
    TYFOXIT F40
    Essotherm 500/Thermaloil
    THERMINOL 55
    User Custom Fluid
    Formulas

    Mass flow = volume flow x ρflow

    power = mass flow x hTF – hTR

    where:

    ρflow = density at flow conditions

    hTF = Specific enthalpy at feed temperature

    hTR = Specific enthalpy at return temperature

    Product Highlight
