The Contrec 515 HC04 is a reliable chemical injection control system designed to measure the volume, mass, and energy content of fluids in heating or cooling systems. It uses single or stacked differential pressure flow inputs along with feed and return temperature inputs for accurate measurements.
This versatile device supports a variety of fluid types and operational modes, making it ideal for numerous heating and cooling applications. Flow calculations are performed using the equations for ISO 5167 or V-Cone meters, ensuring precise results that take thermal expansion into account.
The calculations performed by this instrument are based on the IAPWS Industrial Formulation (1997), which provides accurate thermodynamic properties of steam. The temperature readings are essential for determining fluid density and specific enthalpy. Additionally, the device calculates the isentropic exponent and absolute viscosity, which are crucial for accurate differential pressure calculations in industrial dosing pump controllers.
