Primary Flow Signal's Halmi Parshall Flume Meter Offers Traceable Results Ffor Open Channel Flow Measurement
Accurate measurement for open flow channels
Primary Flow Signal (PFS), the leading designer and manufacturer of innovative, durable, and accurate flow-metering solutions for oil & gas, water/wastewater, and industrial applications, announces that its Halmi Parshall Flume (PFS-HPF) flow meter is providing highly accurate flow measurement for open channel flows in municipal water/wastewater facilities throughout the U.S.
The PFS-HPF meter for open channel flows handles excessive pipe slope or velocity conditions which can cause the traditional Parshall Flume to generate inaccurate measurements. The PFS-HPF design is traceable to the U.S. National Institute of Standards and Technology, and also has a discharge coefficient that significantly reduces environment induced measurement errors. The self-supporting design of the PFS-HPF allows for a wider minimum to maximum flow rate range with the addition of secondary Primary Flow signal devices. With laboratory flow calibration, the PFS-HPF accuracy is +/-1.0% of max rate which is much lower headloss compared to the Parshall flume.
“Accurate measurement of open channel flows is becoming increasingly important, not only from a business and billing perspective, but also for water conservation purposes,” said Bruce Briggs, President of Primary Flow Signal. “Engineers and water management personnel are telling us that only the highest quality and most accurate flow measurement devices, like our Halmi Parshall Flume meter, can be relied upon to deliver reliable, traceable results.”
PFS’s metering solutions are designed and manufactured in the United States by the industry’s largest team of specialized hydraulic engineers, backed by extensive laboratory and field testing, ISO 9008-2008 certification, and efficient vertically-integrated facilities.
