Flow Metering that Outperforms in the Most Demanding Environments
 
HHR FlowPak  •  A technological advancement in differential pressure flow metering.
Designed from the innovative velocity profiling technology of the FTI Translineal Flow Plate and the field proven performance of the HHR Flow Tube, the HHR FlowPak consistently outperforms other flow measurement technologies in the most demanding flow environments.
•  Highest Accuracy
•  Energy Efficient
•  Installation Versatility
•  No Upstream and Downstream Piping Requirements
•  Broad Range of Applications
HIGHEST ACCURACY / PROVEN PERFORMANCE  •  The HHR FlowPak delivers proven performance based on extensive laboratory and field testing.
Empirical data from Alden Research Laboratory show the coefficient of discharge of the HHR FlowPak to be constant, independent of Reynolds Number, and within + 0.5%  of the predicted value, even when installed directly after two elbows out of plane. This eliminates the need for calibration testing to characterize the coefficient and accuracy of each individual meter. When a higher degree of accuracy is desired, the HHR FlowPak can be calibrated at a laboratory whose data is NIST certifiable to an accuracy of + 0.25%. Documentation is available.

ENERGY EFFICIENCY  •  The HHR FlowPak provides superior energy efficiency.
Low permanent pressure loss (PPL) equates to energy efficiency and reduced operating cost. The HHR FlowPak has a lower permanent pressure loss than the orifice plate, Annular Orifice, flow nozzle or wedge meter. In an orifice plate the flow impacts with an abrupt surface and typically results in a PPL of 2 psig. The HHR FlowPak has a smooth, contoured, obstruction free entrance with a pressure recovery cone for enhanced pressure recovery. In many cases the recurring operating cost savings offered by the HHR FlowPak in such applications as high pressure, high temperature steam can actually pay for itself in a very short period of time.

INSTALLATION VERSATILITY  •  The HHR FlowPak provides installation versatility in challenging situations.
The unique design ensures that a flow velocity profile is well developed and properly defined prior to measurement. Fluidic Techniques has conducted extensive performance testing on the HHR FlowPak at Alden Research Laboratory utilizing two close coupled 90 degree elbows out of plane immediately before and after the meter. Test results show  high accuracy and performance with NO ADDITIONAL UPSTREAM AND DOWNSTREAM PIPING, even in disturbed flow applications. This key feature assures installation versatility in tight piping systems whether new construction or retrofit. This can result in significant cost savings in larger, more expensive line sizes.
 
INSTALLATION VERSATILITY

NO UPSTREAM PIPING REQUIREMENTS
The HHR FlowPak adapts to the tightest piping systems without compromising performance. When governing codes increase upstream piping requirements, Fluidic Techniques designed the solution.
RANGE OF APPLICATIONS  •  The HHR FlowPak is virtually unlimited in scope.
There are essentially no limitations to flow measuring applications for the HHR FlowPak. They can be used in natural gas, most chemicals, gasoline, oil, hydrogen, oxygen, LNG, etc... The HHR FlowPak meets the toughest flow measurement challenges such as high temperature, high pressure main stream, and high pressure boiler feedwater, petrochemical, power plants and offshore platforms.
