KATflow 180 – Gas Clamp-On Ultrasonic Flow Meter

The KATflow 180 is specifically designed to enable gas flow measurements across an exceptionally wide range of applications: from high-pressure applications to those involving low or atmospheric pressure. Unlike conventional clamp-on systems, the KATflow 180 delivers reliable measurements even under pressure conditions below 5 bar—a range that was previously considered technically nearly impossible to achieve. 

This is made possible by newly developed sensor technology, advanced digital signal processing (DSP), adaptive filtering methods, and optimized signal algorithms. The innovative shear and Lamb wave sensor technology enables measurements on all commercially available pipe materials with diameters ranging from 25 to 1,500 mm and flow velocities from 0.1 to 75 m/s. At the same time, the universal sensor design reduces the number of sensor types required, offering a significant advantage in procurement, spare parts management, and installation. 

For safe, long-term use, the KATflow 180 is available in two durable explosion-proof housings: an epoxy-coated aluminum housing or a particularly robust stainless steel version. This makes the device suitable for both protected industrial environments and Zone 1 and 2 hazardous areas. The keypad is operated safely via a magnetic stylus through the glass-protected front panel—conveniently and without opening the housing. 

With additional inputs for temperature, pressure, and compressibility factor (real gas factor), the KATflow 180 delivers precise, traceable measurement results even with complex gases and varying operating conditions. Extensive data analysis capabilities provide flexible options for monitoring and process analysis. 

The KATflow 180 combines precision with versatility. Its exceptional measurement range, modern sensor technology, and explosion-proof design make it ideal for continuous gas flow measurements.
