WR200-F - heat energy meter for liquid heat carriers - 1

HEAT ENERGY METER WR200-F for liquid heat carriers Heat transfer water or other liquids Temperature range -50...0...+250 °C Any flow sensor with analogue signal connectable 2 x Pt100 inputs for advantages and return temperature Exact k-value calculation for IAPWS-IF97 Backlit alphanumeric LCD display (4 x 20 characters) Built-in clock with automatic calendar to 2099 Counter for heat and flow resettable Counters for variable periods 4 analogue outputs for instantaneous values 2 pulse outputs for M-Bus connection (optional) Housing for snap-rail or wall mounting (IP55) Accessories for panel installation Description The heat meters WR 200 F is used for detecting the heat energy in closed heating or cooling systems with liquid heat transfer medium. The instantaneous heat capacity is calculated using the formula 134 Arthur Grillo GmbH · Ratingen = heat output in kW = flow in m3 / h = temperature difference between flow and return temperature = thermal coefficient in kWh/m3 · °C subsequently, the actual flow and the current. Thermal power integrated over time and added up to two counters. For counting on an adjustable period of two resettable counters in conjunction with a clock with automatic calendar are available. All measuring and counts are displayed on a backlit four-line LCD display with its physical unit. Dimensions (mm) rail housing Water as a heat carrier may, however, other fluids (water-glycol mixtures, heat transfer oil) are used. The thermal coefficients of water are stored in the unit for a temperature range of 250 °C. Arthur Grillo GmbH · Ratingen The heat energy meter is provided for connection of any flow sensor with analog output. For temperature measurement, two Pt100 inputs are available in four-wire circuit. External records, the unit provides four analog output signals 0/4...20 mA and two pulse outputs can be connected to an M-bus module. All components are housed in a housing profile for snap track mounting with external clamps. Accessories for panel mounting parts and a plastic housing for wall construction are also available. 152 Dimensions (mm) wall constuction Arthur Grillo GmbH · Ratingen panel cut-out panel mounting ACCESSORIES M-Bus Logger M-Count 2C
