Katronic Technologies Ltd. specialise in clamp-on ultrasonic flow meters and non-invasive process measurement instrumentation.
The company employs state-of-the-art electronics and sensor technology to produce clamp-on flow meters that are highly reliable and easy to operate.
The clamp-on ultrasonic flow meters of the KATflow series can measure on pipes of every common material and diameter.
Visit Katronic at the Hannover Messe
We would like to take this opportunity to invite to you to come and see us at this year´s Hannover Messe exhibition. The event runs from the 7th to the 11th April and will highlight all of the KATflow range of ultrasonic flowmeters as well as a few surprises. We look forward to seeing you there.
KATflow 150: Multi-functional flow meter for permanent installation
Behind the Technology
The KATflow clamp-on flow meters work on the transit time ultrasonic principle. This, put simply, involves sending and receiving ultrasonic pulses from a pair of sensors and examining the time difference in the signal. This is a more direct method of determining flow rates than some other systems and provides reliable measurements.
Ultrasonic transducers are mounted on the external surface of the pipe and are used to generate pulses which are passed through the pipe. The flowing liquid within causes time differences in the ultrasonic signals, which are then evaluated by the flow meter to produce an accurate flow measurement.
The key principle of the method applied is that sound waves travelling with the flow will move faster than those travelling against it. The difference in the transit time of these signals is directly proportional to the flow velocity of the liquid and consequently the volumetric flow rate.
Whilst elements such as flow profile, type of liquid and pipe material could have an effect on the measurement, the electronics of the flow meter compensate for and adapt to changes in the medium in order to provide reliable measurements.
