The KATflow range of non-invasive flowmeters utilisesultrasonic technology for the accurate flow measurementof liquids in full pipes.The KATflow 140 is suitable for permanent installations throughout the plant for applications where a non-invasivemethod of flow measurement is of paramount importance.The measurement of flow is based on the principle thatsound waves are influenced by a flowing medium.Measurements are made by penetrating the pipe withultrasound and subsequently time differences, frequencyvariations and phase shifts of the ultrasonic signals are evaluated. This measuring technique has no effect onthe flowing liquid. There is no pressure loss in the pipe and no wear on components of the measuring device.The ultrasonic sensors are clamped onto the outside ofthe pipe, thus eliminating the need to dismantle the pipework and interrupt the process. The KATflow 140 can be applied to any type of standard pipe carrying clean or dirty liquids.

Advantages

• Low installation effort and costs

• Measurement is independent of fluid conductivity and pressure

• No pressure loss, no possibility of leakage

• Retrospective installation for existing plants possible

• No cutting of pipes necessary, no interruption of process, no plant shut down

• No additional fittings for maintenance required

• Hygienic measurement, no risk of contamination,suitable for ultra clean liquids

• No contact with medium, no risk of corrosion whenused with aggressive media

• Cost advantages when used with large diameter pipes, high pressure systems, etc.

• Low stocking costs, nearly all pipe sizes are covered with only 2 types of sensors
