Product information

SITRANS F S clamp-on ultrasonic flowmeters

Siemens is a pioneer in the use of Lamb wave transit-time sensors for clamp-on flow measurement. We call it WideBeam® – and it increases accuracy by reducing sensitivity to any changes in the fluid. How? WideBeam® technology uses the pipe wall as a waveguide to optimize the signal-to-noise ratio and provide a wider area of vibration. These high-performance sensors are designed for steel pipes, but they also work with aluminum, titanium and plastic.

Taking Clamp-on Ultrasonic flow measurement to a new level of performance

How does an ultrasonic flow meter work?

When traveling in the same direction as a flowing medium, ultrasonic waves move faster than waves traveling against the flow. Ultrasonic flow meters use this principle to accurately measure the volume of many liquids and gases – and also to derive parameters like density and viscosity. Watch the video to learn more!
