Custody transfer BTU meter for recording heat quantities of water
The BTU meter RH33 is used in applications with liquid energy carriers.
Benefits
- 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
Recording and billing the quantities of heat and cold in:
- Heating circuits
- Cooling circuits
- Combined heating and cooling circuits
