Venturi flowmeter

Dwyer Instruments has released a Venturi flowmeter with a Magnehelic gauge that is designed to measure the flow of compatible gases while keeping the pressure drop through the meter at a minimum.

The flowmeter is fabricated from aluminium for line sizes up to 100 mm and has a gradual Venturi profile to reduce pressure losses through the meter. Flexible connections enable the meter to be used in vertical or horizontal applications. A Magnehelic gauge provides a large, clear and accurate display of differential pressure readings. Each standard meter is calibrated at standard atmospheric conditions and the gauge reads in inches of water column and SCFM. The Venturis are available in line sizes from 25 to 100 mm and can handle vacuum and pressure applications. The meter is able to handle flows ranging from 20 to 620 SCFM. Applications include soil remediation equipment, process optimisation and channelling/plugging indication.
