History of Primary Flow Signal
Founded in 1995, Primary Flow Signal emerged with a mission to revolutionize venturi-based flow measurement. The company’s founders recognized the need for non-intrusive, low-maintenance flow meters that deliver high accuracy across a wide range of temperatures, pressures, and fluid types. These early innovations quickly earned trust across municipal water treatment plants and industrial process facilities.
Over the years, Primary Flow Signal has expanded its product line to include self-cleaning integrated valves, advanced controllers, and digital communications capability—while maintaining the precision of its core Venturi designs. The company has flourished thanks to its commitment to R&D, regulatory compliance, and customer collaboration. Today, their products are installed in thousands of sites across North America, trusted for demanding flow measurement needs in water, wastewater, chemical, and HVAC applications.

Frequently Asked Questions (FAQs)
What is a Venturi flow meter?
- A flow meter using a converging–throat–diverging venturi tube that measures rate via differential pressure with no moving parts.
Are Venturi meters suitable for sludge or slurry?
- Yes—they tolerate suspended solids, abrasive slurries, and high-viscosity fluids thanks to rugged construction and self-cleaning properties.
Do Venturi meters cause pressure drop?
- Minimal—typically 2–5 psi across the throat, much lower than orifice plates or turbine meters.
Can I get a flow controller with my meter?
- Yes—Primary Flow offers integrated valve-controller combos for real-time flow regulation.
What accuracy do these meters offer?
- High—standard accuracy is ±0.5% full scale with turn-down up to 50:1 under proper calibration.
How do I choose the correct tube material?
- Material depends on fluid chemistry: use PVC/PVDF for corrosives, 316 SS for general use, duplex or Hastelloy for aggressive conditions.
Are there sanitary or Ex-rated models?
- Yes—models are available in sanitary stainless and explosion-proof-certified versions for hazardous environments.
How often is recalibration required?
- Typically every 12–24 months, depending on process chemistry and plant QA procedures.
Is digital telemetry available?
- Yes—meters support 4–20 mA and HART; custom fieldbus options available on request.
How do I select the right size?
- Siewert Equipment’s engineers assess flow range, pipe material, fluid properties, and system pressure to recommend the right meter size.
