The KATflow clamp-on ultrasonic flow meters work on the transit-time method. This is based on the principle that sound waves travelling with the flow will move faster than those travelling against it. The resulting difference in transit-time is directly proportional to the flow velocity of the liquid and consequently to the volumetric flow rate.

The ultrasonic transducers (sensors) of the flow meter are mounted on the external surface of the pipe and are used to generate and receive pulses. The flowing liquid within causes time differences in the ultrasonic signals, which are evaluated by the flow meter to produce an accurate flow measurement. The advanced electronics of the flow meter compensate for and adapt to changes in the flow profile and medium temperature to deliver reliable measurements.

The KATflow 150 is a fixed-installation clamp-on ultrasonic flow meter for non-invasive and nonintrusive flow measurement of liquids and liquefied gases in fully filled pipes. It can be supplied with one or two measurement channels. This enables the flow meter to simultaneously monitor up to two separate pipes. Alternatively, a dual-channel setup can be used for a multi-path mounting configuration of the sensors on one single pipe. Additionally, the KATflow 150 offers optional functions for heat quantity and concentration measurement with process input, output and serial communication options available. These features are complemented by an optional internal datalogger and software for the recording and download of measured values. Thanks to its intuitive instrument menu, Setup Wizard, and Audible Sensor Positioning Assistant TM the flow meter can be set up and its sensors correctly installed in a matter of minutes. Optional transmitter and transducer versions are available for installation in hazardous areas.
