Digital heat meter ERW700

ERW700 Flow rate and thermal energy calculator for liquids, gases and water steam ERW 700 uses input data such as flow (differential pressure), pressure, temperature and density to calculate the volume, standard volume and mass of liquids, gases and steam. Applications Billing meter for district and local heat System monitoring in energy plants For heat/cold production in the middle and upper performance range For greater measuring accuracy and reliability requirements Specifications Suitable for gas, liquids (thermo-oil, glycol, etc), steam and water Can be combined with all conventional volume sensors (differential pressure, vortex, turbine, dynamic pressure, cross probe, ultrasonic, MID, coriolis) High-precision process calculation of density, enthalpy and compressibility based on equations or extensive database 2 independent 24 Bit AD converters for resistance (temperature) and current input, calculation speed 10 re-evaluations per second Compensation input for density signal Logger functions for 2 fixed dates, up to 30 monthly values, up to 800 periodic memory, 100 error memory, 100 parameter memory and min/max memory entries (31 days,12 months) Parameterization and operation via PC software and/or manually via a keyboard Separate LC display (e.g. for switch cabinet door installation) Extensive modular extensions for inputs and outputs Various special functions, such as condensate measurement, bi-directional measurement, tariff or fault counters, etc. Large backlit graphical display, flexible configuration
