Paddle Wheel Flow + Temperature Meter P75 with Dual 4–20 mA, Pulse, and Switch Outputs

Paddle Wheel Flow + Temperature Meter P75 with Dual 4–20 mA, Pulse, and Switch Outputs

Paquin is spotlighting our P75 Paddle Wheel Flow Meter and Temperature Meter, a durable, high-performance solution for industrial flow and temperature measurement with versatile installation options and multiple output formats for seamless controls integration.

View the P75 datasheet (PDF)


Built for: Water & wastewater, hydraulic/lube systems, industrial cooling loops, braking fluid measurement, oil & gas monitoring, and more

Delivers: ±2% of full span accuracy across ¾″...6″ pipe sizes

Integrates via: 4...20 mA (flow) + 4...20 mA (temperature), pulse, and two switching outputs (PNP or NPN)

 

The Problem The P75 Solves

Many industrial utility systems need more than “just flow”. They need flow + temperature for control, alarms, and equipment protection. P75 combines both measurements with flexible outputs (analog, pulse, and switching) while maintaining serviceability through removable wetted sensor components.

 

What’s New / Why It’s Different

  • Versatile installation: Available with weldable insert, ANSI Class 150 flanges, or NPT threaded options to match existing piping

  • Multi-signal flexibility:Two 4...20 mA channels (flow + temp), pulse output for flow, and 2 programmable switching outputs (PNP or NPN)

  • Industrial durability: Stainless body, aluminum housing, PVDF rotor, and high-pressure resistance up to 435 psi (30 bar)

  • Local visibility: Integrated LCD display

 

Applications

  • Water & wastewater treatment

  • Hydraulic oil and lubricating systems

  • Cooling systems for industrial equipment

  • Braking fluid measurement

  • Oil & gas flow monitoring

  • Machine manufacturing / process control
