PCE Deutschland flow meter PCE-TDS 100HSH

The ultrasonic flow meter is required in the context of a control measurement or for the quick determination of the flow in a pipeline and is therefore a transportable / easy to install measuring system. The ultrasonic flowmeter works according to the transit time difference method. The measuring principle of the flowmeter is quite simple.

When measuring a pipe obliquely with the flow, it takes less time than when measuring against the flow. The stronger the flow becomes, the longer it takes against it and the faster it becomes with it. The difference between the flow times with the flow or against it is therefore directly dependent on the flow velocity of the river. The flowmeter uses this effect to determine the flow velocity and flow rate.

In this process, electro-acoustic transducers (Piëzo effect”) transmit and receive short ultrasonic pulses through the medium flowing in the pipe. The transducers are located longitudinally offset on both sides of the measuring tube. The non-destructive sensors are placed on the pipe and fastened, for example, by means of a cable tie. Within a short time, the display shows the flow velocity. The ultrasonic flowmeter can be used for measurement on metallic pipes, plastic pipes or rubber pipes.
