Paquin is spotlighting our P77 High Turndown Turbine Flow Meter, a compact, rugged 316 stainless turbine flow meter for precision liquid measurement, with configurable sensing and output options for demanding industrial environments.
The P77 is a high‑performance turbine flow meter that converts liquid flow velocity into a standardized electrical signal using a turbine/detector system, offering fast response and configurable outputs to match modern controls and test systems.
Built for industrial realities:
- Broad Measuring Range: 0.01…449 GPM (0.04…1700 L/min), 5800 psi (400 bar) rating, IP67, 0.5% accuracy with ±1% of reading repeatability.
-
Output flexibility: choose analog, pulse, linearized pulse, display-integrated, or Ex proof display configurations.
The Problem The P77 Solves
When applications demand repeatable liquid flow measurement across varying operating points, especially in skid systems, industrial process loops, or validation rigs, teams need a meter that’s accurate, robust, and easy to integrate. The P77 supports multiple sensing and output styles so you can standardize your mechanical footprint while selecting the signal type your PLC/DAQ expects.
