SERIES VFLO VENTURI FLOWMETER WITH MAGNEHELIC® GAGE
±2.5% Accuracy, Dual Scale in SCFM & in w.c.
The Series VFLO Venturi Flowmeter with Magnehelic® Gage is fabricated from aluminum and has a gradual Venturi profile to reduce pressure losses through the meter. Flowmeter can be used in a vertical or horizontal position just by rotating the Magnehelic® gage. The Magnehelic® gage provides a large, clear and accurate display of your differential pressure reading. Each meter is calibrated at standard atmospheric conditions. The dual scale reads in SCFM and in w.c. The meter is supplied with easy to read reference charts for various flow conditions. It is available in line sizes from 1" to 4" and can handle vacuum and pressure applications.
To place an order for the Venturi Flowmeter with Magnehelic® Gage, see the Magnehelic® Configurator.
