Primary Flow Signal, Inc. is a leader in the design and manufacture of Venturi differential flow meters. Field-proven in
hundreds of thousands of installations worldwide, differential metering ensures the most accurate and reliable metering available anywhere. Through innovation in design and manufacturing, coupled with peerless engineering and technical expertise, PFS delivers customers versatile, ultra-long lasting liquid and gas metering solutions for a variety of applications and industries.
The HBX-1 Halmi-Briggs Venturi primary flow element delivers metering accuracy, performance, and reliability over a wide flow range for a broad array of application requirements.
With repeatable +/- 0.25% lab calibrated accuracy and a stable linear coefficient of discharge, the HBX-1 Halmi-Briggs Venturi exceeds competing products.This design is ideal for full pipe flow of gas, liquid, and steam for applications, such as water, wastewater,oil and gas, industrial, commercial, and others. Coupledwith our state-of-the-art secondary instrumentation,PFS’s differential metering delivers industry-leading reliability and accuracy. It can also cut costs by mitigating requirements for linearization software, computers, or other secondary signal conditioning.
All PFS products are proudly made in the U.S.A.
