WAFS – 103

DIFFERENTIAL PRESSURE PITOT TUBE FLOW METER

The WAFS 103 Differential Pressure Pitot Tube flow meter is based on the pitot tube principle to measure the flow in your compressed air system. The sensor can measure in wet and dirty gases. It can be installed under pressure and measures flow, pressure, temperature, and total flow simultaneously.

The sensor features long term stability, wide turn-down ratio and good temperature stability. It can be used in compressed air and non-corrosive gases. Through a 1/2” G-type ball valve the sensor can be inserted into the pipe under pressure and Various output signals allow the sensor to be connected to the Energy Management System (EMS) or Building Management System (BMS).

Frequently Asked Questions

What is a pitot tube flow sensor?

A pitot tube flow sensor measures compressed air flow velocity by detecting the difference between static and dynamic pressure in a pipe. The WAFS 103 converts this pressure differential into an accurate flow reading.

How accurate is the WAFS 103 flow sensor?

The WAFS 103 pitot tube flow sensor provides measurement accuracy of +/-2% of reading, suitable for compressed air monitoring, energy audits, and leak detection applications.

What pipe sizes does the WAFS 103 support?

The WAFS 103 supports a wide range of pipe diameters through insertion-type installation, making it versatile for various industrial compressed air systems.
