Ultrasonic Flowmeters for Thermal Energy Measurement

KATFLOW 100. KATFLOW 150. KATFLOW 230.

Three of the Katronic clamp-on ultrasonic flowmeters can be supplied as heat quantity measurement instruments and are increasingly being used as portable and permanently installed energy meters by various industries and municipal organisations. The clamp-on mounting technique of the flow and temperature sensors enables the flowmeters to measure heat quantity non-invasively without the risk of interruption of flow, pressure drop or leakage.

The use of clamp-on flowmeters as energy measurement devices requires a pair of ultrasonic flow sensors installed on a suitable pipe section and two PT100 temperature sensors. The PT100s are mounted on the inlet and outlet pipes of the chosen system. The flowmeter then makes use of the flow data, the differential temperature and the specific heat capacity of the flowing medium in order to calculate the energy consumption.

The KATflow 150 and KATflow 100 are used for permanent installation on a variety of HVAC applications and can easily be embedded into automated building management and control systems. The portable KATflow 230 is employed for spot measurements as part of energy consumption surveys. All of the energy meters offer process outputs including current outputs, open-collector outputs with totaliser pulse, and digital relay outputs. Additionally, the KATflow 150  and 100 can be equipped with an RS 485 or Modbus for ease of integration.
