Talk to an expert

The S430 Pitot Tube Flowmeter provides flow and consumption measurement in wet air or high mass flow and velocity applications. Based on the pitot tube principle, the sensor features long term-stability, wide turn-down ratio and good temperature independence. It can be used in compressed air and non-corrosive gases.

Optimum Compressor Efficiency and Performance

The S430 compressed air flowmeter is designed for the use in wet air, therefore it can be used directly at the compressor outlet. With this kind of installation other flowmeters are likely to fail, as they are not able to withstand the wet and hot air. The S430 is able to withstand these conditions, making it the perfect tool for compressed air audits and compressor efficiency measurements.

Various Output Signals

The S430 Pitot Tube Flowmeter is perfectly suited to be integrated into process controls or high-level monitoring systems. Various output options are offered for a seamless integration:

Isolated 4… 20 mA output for actual flow readings
Isolated Pulse output for totalizer
Modbus/RTU to read all values digitally
Modbus/TCP for connections to high level systems
M-Bus for metering networks

Flexible and Easy Installation

The S430 Insertion Type Flowmeter can be installed in tube diameters of 1’’ to 10” through center installation and bigger diameters through a non-center installation. Due to the insertion through a 3/4″ ball valve, the S430 can be installed under pressure and is perfectly suited for installations where shutdowns are not acceptable.

Robust Material

The S430 comes with an IP65 casing, which provides robust protection in harsh industrial environments. All parts which come into contact with the measurement medium are made of 316L stainless steel. This ensures longevity and guarantees a reliable measurement.

Remote Configuration and Live-Data

By connecting the S430 with the free S4C-FS mobile app, the operators are enabled to view online-data as well as configure flow meter settings.

It is all these features that make the S430 Pitot Tube Flowmeter a perfect choice for accurate and reliable compressed air flow monitoring in wet and dirty gases that occur, for example, at the discharge of a compressor.
