HEATING METER CALCULATOR APPLICATION QALCOMET HEAT 1 is designed for metering and monitoring of heating and cooling energy in closed or open heating/cooling systems, installed in dwelling houses, office buildings or energy plants. The calculator QALCOMET HEAT 1 is a sub-assembly of a heat meter, together with standard flow sensors (based on ultrasonic, electromagnetic or mechanical measurement principle with standard pulse output), temperature and pressure sensors. QALCOMET HEAT 1 measures and calculates supplied flow parameters, displays measurement data on the display, records and stores data in the internal archive. • High accuracy • Universal (applicable with any flow sensor with standard pulse output). • Can be used to calculate energy values for two independent heating systems • Cold water temperature for open system application can be measured or fixed (pre-programmed). • Flexible menu setup - list of parameter values displayed on the LCD may be configured according to the customer's needs. • User may select one of seven possible installation diagrams according to the application type • Up to 5 flow measurement inputs. • Two channels for pressure measurement. • Optical data interface according to EN 61107. • Up to 12 years battery supply or 230V mains supply. • Battery lifetime up to 12 years. • Fulfils "C" class environment protection requirements • Programmable built-in alarm relays or regulation functions. • Metering archive • Optional communication modules • Mounting in any installation position

Integrated into the front panel of calculator. It is designed for data reading via M-bus protocol and parameterization of the meter. The internal radio provides data reading via WMBUS telegram: • Optical interface. • Two configurable pulse-frequency outputs. • Two configurable current outputs 0-20mA or 4-20mA. • Configurable double relay output for limiting regulation or alarm function. • Pulse output Following daily, weekly and monthly parameter values are recorded in calculator's memory: • Absolute integral instantaneous parameter values • Hourly, weekly and monthly alterations of integral...
