Averaging Pitot Tube Flow Meter

The averaging pitot tube flow meter is a differential pressure flow meter that requires the least installation effort of all DP flow meters. It is cost-effective and suitable for a variety of applications in the municipal water and wastewater industry. Its low remaining pressure loss as well as its bi-directional flow capabilities make it ideal for water, sea water, condensate, cooling water, saturated and superheated steam, and many other liquids and gases. It is also suitable for dust-laden gases at high-temperatures.

Furthermore, this averaging pitot tube flow meter, from KROHNE, covers big diameters, round and rectangular pipes, and ducts. It requires only short straight inlet/outlet pipe sections (7D/3D). Due to the low flow profile constriction, it generates only a minimal residual pressure loss.

We offer the complete DP flow solution with averaging pitot tube, valve, manifold, and DP transmitter. They come pre-assembled, ready for operation, and only need a single flange or weld-on fitting for installation in a process line. This reduces engineering and installation efforts as well as eliminating the need for routing of impulse lines, valves, and supports. Retrofit and retractable as well as pressure or temperature-compensated versions with flow computing are also available.

DP Pressure Transmitters for Flow Measurement

The sophisticated OPTIBAR DP 7060 and OPTIBAR DP 3050 DP transmitters are the perfect companion for this DP flow meter solution. They are 3D linearized and also ensure advanced performance even at high static pressures. The OPTIBAR DP series has outstanding long-term stability and a low total cost of ownership while reducing the need for field calibrations.
