The clamp-on ultrasonic heat meter is combined by our high accuracy clamp-on ultrasonic flow meter together with standard platinum temperature sensors (PT100 or PT1000),then get result of thermal energy measurement transferred from flow measurement  in a closed pipe accordingly.


The ultrasonic heat meter system mainly includes three parts: the main unit, the ultrasonic clamp-on type transducers, and the temperature sensors(PT100 or PT1000). The main unit is a high-accuracy ultrasonic transit-time flowmeter. Its enclosure can be a standard version or an explosive-proof version. The ultrasonic transducers are clamp-on type and very easy to install. The temperature sensors can be standard Pt sensor or customer-supplied sensor.


The calorimeter can be used for energy consumption measurement of a heating / cooling system in office buildings, apartment complexes, or any  liquid-based thermal energy production system. It can also be used to monitor the efficiency of an energy production system such as HVAC installation.


Key Features:

  • Horizontal or vertical Installation 
  • Transducer Max Temp: -20C to +160C
  • Accuracy: +/-1% of reading above 0.6ft/sec / 0.2 m/sec
  • Outputs available: 1x 4-20mA , 1x Pulse Output , 1x Alarm Output (All configurable)
  • ModBus output
  • Ingress Protection: Display= IP65, Transducers= IP65 (IP68 on request)


These ultrasonic flow meters can be used on virtually any pipe size or material, are non-invasive and are therefore not prone to the levels of deterioration that are seen by traditional intrusive flow meters. Mbus converter, Radio Pulse transmission and GSM/GPRS Telemetry / logging options on request.
