according to the time difference method / for determining flow velocity and flow rate / Measuring method for liquids that are as homogeneous as possible
The ultrasonic flow tester is required as part of a control measurement or for quickly determining the flow in a pipeline and is therefore a portable / easy-to-install measuring system. The ultrasonic flow meter works according to the transit time difference method. The measuring principle of the ultrasonic flow meter is quite simple.
Measuring a pipe obliquely with the flow takes less time than measuring against the flow. The stronger the current, the longer it takes to fight it and the faster you go with it. The difference between the flow times with the flow or against it therefore depends directly on the flow velocity of the river. The ultrasonic flow meter uses this effect to determine flow velocity and flow rate.
Electro-acoustic transducers (“piëzo effect”) send and receive short ultrasonic pulses through the medium flowing in the pipe. The transducers are offset in the longitudinal direction on both sides of the measuring tube. The non-destructive sensors are placed on the pipe and e.g. attached with a cable tie. The display shows the flow velocity within a short time. The ultrasonic flow meter can be used to measure on metallic pipes, plastic pipes or rubber pipes.

The ultrasonic material thickness meter is a compact measuring device for metals, glass and homogeneous plastics. This ultrasonic testing device works with an external ultrasonic probe, this probe guides ultrasonic waves into the material to be tested. Different materials transmit ultrasound at different speeds, so you can select different ultrasound speeds on the ultrasound tester.
With the thickness gauge, you can determine the material thicknesses of metal, glass and plastics and other homogeneous materials in seconds. The operation on the ultrasonic testing device is very easy using the seven buttons. This measuring device can be calibrated on site with little effort using the integrated calibration block. All measured values can be transferred to the PC and analyzed using the optionally available software. The software also offers the option of exporting the data to Microsoft Excel.
