Electronic heat meter, wall mounted

The heat meters are electronic dry-runners. They acquire the flow acquisition without generating a magnetic field and use highly accurate temperature sensors. They are used in residential and commercial buildings for acquiring heat or cooling energy consumption. Day by day they transmit the current measured values and consumption on the set day to the associated data collectors.The heat meters are available as single-jet or measuring cell models in different sizes, enabling them to be installed on all types of standard plant. The tenant can see his individual consumption on a large, easy-to-read display. The built-in lithium battery powers the device for a period of time exceeding the calibration period.Data transmission via M-bus, pulse, or the AMR remote meter readout system.The heat meter has 3 display levels which show the following values and variables:

• Cumulated heat consumption since the heat meter was first installed
• Cumulated heat consumption since the last set day
• Segment test
• Current heat output- Current flow rate
• Current flow temperature
• Current return temperature
• Current temperature differential
• Heat meter’s number of operating hours since it was first installed
• Set day and set month
• Stored heat consumption of previous year
• Stored heat consumption of the last 13 months
• Verification code
• Indication of errors
• Cumulated volume since the heat meter was first installed

The units displayed are ?C or K, kWh (or GJ on request), m?/h, kW and hours.Standard display is the cumulated heat consumption.
