Flexible installation (DN50 up to DN900)

The S431 OEM Compressor Flow Meter for Wet Air is developed to measure the compressor performance inside or at the outlet of the compressor. The flow meter provides accurate and long-term stable measurements of the compressed air flow directly at the discharge of the compressor. This is supported by the built-in Auto-Calibration, which removes any temperature or aging drift.

Robust Design for OEM Compressor Applications

Due to the robust design, the S431 OEM Flow Meter can withstand high temperatures and vibrations of any industrial OEM application. At temperatures up to 90 °C, other flow meters are likely to fail due to the hot and wet air.

Pitot-Tube Technology

The S431 OEM works on the principle of the pitot tube. This design allows building up a pressure difference (Δ Pressure) with the sensors probe. This is a direct indicator of the air velocity. The mechanical design makes it resistant to water or other contamination in the air flow.

Various Output Signals

The S431 OEM Pitot Tube Flow Meter is perfectly suited to be integrated into process controls or high-level monitoring systems or compressor controls. Various output options offer great flexibility: Isolated 4… 20 mA & Pulse; as well as Modbus/RTU

Flexible and Easy Installation

It offers an easy and flexible installation while fitting pipe sizes from DN50 up to DN900.

Compressor Efficiency and Performance

The S431 OEM Compressor Flow Meter is the perfect flow meter for quality conscious compressor makers by measuring the air delivery directly inside the compressor or at the compressor discharge.
