SITRANS FS Thickness Gauge

USA - Thickness gauge

Stand-alone Tool for Clamp-on Flow Meters

The easy-to-use, stand-alone digital ultrasonic pipe wall thickness gauge is an indispensable tool in accurate clamp-on ultrasonic flow measurement. Since even the smallest miscalculation of the pipe wall thickness can have a major impact on a clamp-on flowmeter's accuracy, the pipe thickness gauge has to be extremely precise.

The SITRANS FS Thickness Gauge for clamp-on ultrasonic flow meters operates at a 5 MHz frequency, enabling it to measure even the smallest pipe thickness. Although the thickness gauge was originally designed to increase the accuracy of clamp-on flowmeters, it can be used to measure the thickness of any pipe wall.


The stand-alone Thickness Gauge can be used with the following configurable systems:





  • Measures pipe wall thicknesses easily

  • Works on various metallic and non-metallic pipe materials such as steel, aluminum, titanium, plastics and ceramics

  • Displays results in inches or millimeter
