Digital heat meter 515 HC01

Suited for heating and/or cooling operation Uses IAPWS-IF97 to determine water properties Selection of common industry fluids using internal tables Facility for user defined Enthalpy and Density table Flow meter can be located in feed or return line Allows for Non-Linear Correction Selection of second language and user tags RTC logging with over 1000 entries Infra-red communications port on front panel Pulse width and scaling of pulse output 4-20mA retransmission Selectable protocols on serial ports including Modbus RTU and printer output Front panel adjustment of 8-24V DC output voltage Backlit display LCD Backup The 515 HC01 application measures the volume, mass and energy content of fluid in a heating or cooling system by using frequency volume flow input in conjunction with analog feed and return temperature inputs. A selection of fluid types and modes makes it suitable for many heating/cooling applications. The instrument is compatible with a wide range of flowmeter frequency outputs, including millivolt signals, reed switches, Namur proximity switches and pulse trains via its smart front-panel programming. 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 industry 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
