The HHR Flow Tube is suitable for measuring liquid, gas or steam flow. The HHR Flow Tube is the most efficient differential pressure producing flow measurement device available providing significant savings in recurring operating costs over any other type of primary flow element. In addition to the efficiency, the low permanent pressure loss makes the HHR Flow Tube the ideal choice for flow measurement where accuracy, long life, and low operating costs are essential.Fluidic Techniques' HHR Flow Tube is manufactured in accordance with ASME codes and standards. Custom computer aided design is combined with quality controlled manufacturing to consistently produce the HHR Flow Tube with an accuracy of +/-½%. Fluidic Techniques maintains a database with over 1,200 independent laboratory flow calibrations performed over the last 30 years to substantiate the accuracy of the HHR Flow Tube. Flow Calibration can be performed to increase the accuracy to +/- ¼% if desired.

The HHR Flow Tube can be manufactured in sizes from 1½" up to 48 inch in line size. Pipe wall thickness dictates design.

The HHR Flow Tube is available in Carbon Steel with 304 or 316 throats as standard and can also be furnished in all stainless steel, chrome-moly steel or other exotic materials upon request.
