The Katflow 220 non-invasive ultrasonic flowmeters utilize ultrasonic technology for the accurate flow measurement of liquids in full pipes. The portable device has been designed to meet the needs of the Service/Maintenance and Commissioning Engineer wishing to check the flow rate of liquids at different locations in the plant. The set-up of the unit is simple and user friendly in order to obtain the required flow information in minutes. The ultrasonic sensors are clamped onto the outside of the pipe, thus eliminating the need to dismantle the pipework and interrupt the process. The Kaftflow 220 can be applied to any type of standard pipe carrying clean or dirty liquids.
