Asair AFD4040 Series Vortex Liquid Flowmeter - PPS & SUS304 Stainless Steel, G/RC/NPT Thread
The Asair AFD4040 Series is a vortex flow sensor designed for precise liquid flow measurement in industrial and commercial systems, compatible with PLCs and DAQ systems via 4-20mA or RS485 Modbus output.
Features
- Operates on the Von Karman vortex principle for stable, drift-free flow measurement.
- Constructed from durable PPS and SUS304 stainless steel for chemical and pressure resistance.
- Offers multiple flow ranges (2-16, 5-40, 10-100 L/min) and thread options (G, RC, NPT).
- Provides 4-20mA analog or RS485 Modbus digital output for flexible system integration.
- Rated for high-pressure environments with a maximum pressure of 16 bar.

The Asair AFD4040 Series Vortex Liquid Flowmeter utilizes the Von Karman vortex street principle. As fluid flows past a bluff body (spoiler column), alternating vortices are shed at a frequency proportional to the flow velocity. An internal piezoelectric or capacitive sensor detects this frequency, which the onboard chip converts into a precise volumetric flow rate signal.
Engineered for demanding liquid process control, the sensor’s PPS polymer and SUS304 stainless steel construction ensures long-term durability against corrosion, scaling, and high-pressure surges up to 16 bar. Its fast response time and immunity to drift make it suitable for continuous monitoring in HVAC, water treatment, chemical dosing, and industrial cooling systems.
