Ultrasonic Flow Meter PCE-TDS 100HMHS

Ultrasonic Flow Meter PCE-TDS 100HMHS
According to the transit time difference method / To determine flow velocity and flow rate / Measuring method for liquids as homogeneous as possible

The ultrasonic flow meter is required as part of a control measurement or to quickly determine 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 flow meter is quite simple. Measuring a pipe at an angle with the flow takes less time than measuring against the flow.

The stronger the current gets, the longer you need against it and the faster you get with it. The difference between the flow times with the flow or against it therefore depends directly on the flow speed of the river. The flow meter uses this effect to determine flow velocity and flow. 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 pipe. The non-destructive working sensors are placed on the pipe and fastened e.g. by means of a cable tie. The display shows the flow rate within a short time. The ultrasonic flow meter can be used for measurements on metallic pipes, plastic pipes or rubber pipes.
