Accurate measurement of flows may prove to be difficult and time consuming and may also require a great expenditure of energy.

The ITABAR sensor was developed to serve as a highly reliable instrument to measure liquids, gases and steam. It is distinguished by many advantages over other measuring systems.

Itabar sensors generate a differential pressure (dp) between upstream and downstream sides. This pressure differential is measured and converted into a flow signal. Due to the Itabar sensor design permanent pressure loss at the measuring point is very low compared to other dp based systems (e.g. orifice, venturi). A further advantage is the ease of the sensor installation. The standard Itabar version simply requires tapping the pipe, welding on an assembly sleeve and inserting the sensor.

The Itabar also comes in a flo-tap version, which allows installation and removal of the sensor under pressure.

Applications for ITABAR sensors range from batch control, flow measurement of liquids in the chemical industry to measurement of fuel, air, steam or gas as the primary source of energy. ITABARS are used for demanding tasks such as high volume flow measurement as well as important process control applications requiring a high degree of stability and reproducibility. They can be installed in round pipes or rectangular ducts ranging in size from 25 mm to 12 m (1 inch up to 470 inches). The maximum allowable flow velocity is 10 m/s for liquids, 200 m/s for gases and 60 m/s for steam.
