Petrochemical – In petrochemical complexes it often happens that new instrumentation is needed in an extensive pipe network due to defects, the commissioning or extension of production facilities.

Shutting down the production process is complicated and expensive, and any modification to the pipeline can cause leaks. In addition, the measurement instruments must be resistant to the often corrosive liquids and extreme temperature differences.


  • Suitable for all types of pipelines (incl. PVC, stainless steel duplex and with inner lining)
  • Non-invasive: Measuring from the outside of (existing) pipes
  • Suitable for gases and fluids
  • Cost-effective: No interruption of production processes
  • No pressure loss, No leakage problems, No pollution
  • Diameter range : 10 – 6500 mm
  • Resistant to temperatures > 600 ° C

Our ultrasonic KATflow clamp-on flowmeters are suitable for measurements on almost any liquid hydrocarbon, such as LPG, petrol, diesel, kerosene, fuel and lubricating oil, methanol, ethanol, naphtha, etc.

Not sure whether you can use our flowmeters for a measurement on a specific liquid? Make sure to contact us.

The KATflow 170 offers an ultrasonic measuring solution for permanent installation in explosive environments. Both the transmitter housing and clamp-on sensors of this type of flowmeter are ATEX approved for installation in zones 1 and 2.

The process input and output and serial interface options are available for the device and are easy to implement in your control system. As an extra feature we offer an infringement-free measurement of the concentration function.

Our ultrasonic flowmeters are designed with functionality in mind. The instruments can be supplied in a variety of configurations for different petrochemical applications, such as :

  • Controlling the fluids flow rates over the production process, such as acids and industrial wastewater
  • Determining the product quality by means of sound speed measurement
  • (With inputs for) pressure, temperature or density compensation
  • (With special sensors for) measuring flow rates at very high temperatures

The easiest way to ensure that your staff are not endangered by dangerous or toxic chemicals is to make sure that they are never exposed to them. The use of a clamp-on flowmeter improves safety, eliminates the need for permits and is quick and simple to install and operate.
