Paquin is spotlighting our P79 Vortex Flow Meter for liquids, gases, and steam, with minimal pressure loss, high temperature service, no moving parts, and industrial connectivity.
Built for: steam & energy monitoring, HVAC/process air, utilities/water, chemical, food & beverage, pharma, power, and pulp & paper
Delivers: ±0.75% (liquid) and ±1.5% (gas/steam) accuracy, LCD indication, and outputs including 4–20 mA + pulse, HART + pulse, or RS 485/Modbus
Integrates via: ANSI B16.5 flanges (Class 150/300/600) to 12″, EN 1092 1 flanges to DN300, wafer, NPT/BSPP threads
The Problem The P79 Solves
Plants need one meter that handles steam, compressed gases, and liquids without adding differential pressure or the maintenance burden of moving parts. P79’s vortex shedding principle provides a clean, obstruction free path that preserves pressure, while high temperature capability (up to 662 °F) supports demanding steam services.
What’s New / Why It’s Different
-
Media flexibility: one platform for liquid, gas, and steam
-
High temp design: medium −40…662 °F (−40…350 °C) option
-
Industrial grade I/O: 4–20 mA + pulse, HART + pulse, or RS 485/Modbus with on device LCD
-
Process ready connections: ANSI/EN flanges, wafer, and threaded ends
- Ruggedization & safety: IP65 protection and Exd II BT5 Gb option for hazardous areas
