The patented entrance section to our flow tube is uniquely designed to establish a stable and linear velocity profile. Our tube has been teated by independent flow laboratories on compressible and incompressible fluids.

The power required to operate the system is directly related to the energy required to operate a primary element. Although the cost of a flow tube or TA 2% head loss flow tube may exceed an orifice plate or nozzle, the tubes can recoupe their initial cost by recovering more head pressure.

The new patent can offer 98% pressure recovery, 1 to 20 flow rangeability, keeping accuracies of .50 uncalibreated and .25 calibrated. It is very durable and light weight vs. cast iron. Because the upstream converging entrance is a very special contour shape, it can be manufacturred economically.

Minimize swirl, vortices or any helical disturbances in the flow. The flued must be single phase and no pulsations. The throat must be installed concentric inside the pipe and the pressure taps must be perfect and free of burrs.
