Ultrasonic flowmeters
Our product finder helps you to search for suitable measuring devices, software or system components via product characteristics. Applicator leads you through an individual product selection via application parameters.
Using ultrasonic waves, the flow volume of a wide variety of gases and liquids can be measured reliably – independent of electrical conductivity, pressure, temperature or viscosity. In applications that require traceable and guaranteed accuracy, inline ultrasonic sensors are preferred for use. Clamp-on ultrasonic sensors, on the other hand, are installed on the outer wall of the pipe and thus also enable temporary measurements or a retrofitting.
For retrofitted installation without interrupting the process
Aggressive fluids can be measured without any problems, even under high pressure
Suitable for pipes made of plastic, steel, cast iron composite materials (lined/unlined)
For pipe diameters up to DN 4000 (156")
In-line sensors
Guaranteed accuracy thanks to traceable factory calibration
Robust industrial design in accordance with ASME and EN
Short inlet runs
For pipelines up to DN 300 (12")
The Ultrasonic Flow Measuring Principle
Ultrasonic flow measuring principle
Swimming against the flow requires more power and more time than swimming with the flow. This simple fact is the basis for ultrasonic flow measurement according to the “differential transit time” method: This method uses two sensors, set opposite each other in the measuring tube. Each sensor can alternately transmit and receive ultrasonic signals, while simultaneously measuring the signal transit time.
As soon as the fluid in the tube starts to flow, the signals are accelerated in the direction of flow but delayed in the opposite direction. The differential transit time, measured by the two sensors, is directly proportional to the flow rate.
Benefits
Measurement independent of pressure, density, temperature, conductivity and viscosity (for homogeneous fluids)
Free pipe cross-section, no pressure loss
No moving parts, minimum maintenance and upkeep
Long service life, no abrasion or corrosion from the fluid
In-line or clamp-on design for stationary or temporary flow measurements
