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.
