The Malema VF4000 Vortex Flow Sensor is a karman vortex type flowmeter, sensing the flow by ultrasonic sensor from outside of the pipe.
Vortex Detection with Ultrasonic Sensors:
This flow meter has no liquid pocket and all wetting parts are high quality PFA, specially designed to meet the demands of the semiconductor production lines, where the utmost cleanliness and chemical resistivity is required. The choice for the measurement of ultra-pure water, DI Water, chemical liquids (low viscosity).
Minimum Flow Rate of 3 L/min.
Accuracy: ±3% F.S. (Optional 1%) Repeatability: ±0.2% of Reading (>8L/min)
Fluid Temperature: -20 to 100°C. (no freezing or boiling)
Model VF40X3: for 3 to 70 L/min / 3/4"
(Available with PFA Tube end, Flare Fitting, Pillar Super Type Fitting, etc.)
