Dwyer Instruments Inc. recently released its new Venturi Flow Meter with Magnehelic Gage. It is designed to measure the flow of compatible gases while keeping the pressure drop through the meter at a minimum.
The flow meter is fabricated from aluminum for line sizes up to 4 inches. It 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 gage is said to provide a large, clear and accurate display of differential pressure readings. Each standard meter is calibrated at standard atmospheric conditions and the gage reads in inches of water column and SCFM. The Venturi’s are available in line sizes from 1 inch to 4 inches and can handle vacuum and pressure applications. The meter is able to handle flows ranging from 20 to 620 SCFM.
