3.3 Measuring method and functioning
The ultrasonic sensor works with the time-of-flight measurement principle. The flow rate is
derived from the time difference of the ultrasound with and against the flow direction and the
geometry of the measuring cell. Multiple measuring data are collected by adequate evaluation
algorithms before processing the data for higher accuracy.
The flow rate can be indicated by a current output of [0/] 4 to 20 mA serving as the process
interface.
Additionally the following interfaces are available:

Frequency output for flow rate: 0 to 20 kHz, 5 V digital

RS485 interface: bus-capable

Switching output: configurable as PNP / NPN / Push-Pull, 0 to 30 V

Digital input (MODBus on request)
Please find the descriptions in the “Technical Data Sheet.”
3.4 Requirements for Liquid
The measuring method using ultrasound is suitable for all sound transparent, low-viscosity
liquids.
For industrial applications with high-viscosity liquids such as fats or special paints a higher
pressure drop (at nominal flow) has to be expected. In this case the specified value for nominal
flow cannot be achieved.
3.5 Parameterization, calibration and readout of measuring values (Accessories)
With the SONOFLOW Monitor software (optional) in conjunction with a computer the sensor can
be validated and adjusted to particular measuring tasks. Furthermore using the Monitor, the
measured values can be displayed on a screen. The measurement data can be recorded in a
table and be saved to a file.
All available accessories are listed in the
“Technical Data Sheet”.
