Информация

Calibratable BTU meter for one measuring point with one pulse/analog input for flow and two RTD/analog inputs for temperature/pressure

Recording and billing the quantities of heat and cold in:

Heating circuits

Cooling circuits

Combined heating and cooling circuits

Typical application areas in industry, long-distance heat networks and building automation.

Transparent energy consumption helps you save on energy costs

Calibrated, electronically paired temperature sensors ensure the highest accuracy and enable replacement of individual temperature sensors even for certified devices in the field (without reapproval!)

Tariff counter for requirements-based billing

Detailed data logging of current and counter values and of error messages, off-limit conditions and changes to operating parameters

Standard models are suitable for connecting and supplying all common volume flow transmitters and temperature measuring points

Remote readout via Ethernet and fieldbuses

Verified and certified reliability and accuracy
