Measuring principle and measuring methods

The flow meter enables the flow velocity of liquids in pipes to be measured without interfering with
the pipe and without affecting the flow in the pipe.
To enable non-invasive measurement, the PCE-TDS 200 uses two sensors that work as both
ultrasonic transmitters and receivers. The sensors are attached to the outside of the pipe wall at
a defined distance. To enable the transmission of the ultrasound, a coupling gel must be applied
to the sensors in this case. When ultrasonic signals are transmitted with and against the flow
direction of the liquid, differences in transit time occur which can be converted into the flow
velocity.
The sensors can be mounted according to four different measurement methods which are shown
below.
