Dwyer Instruments has launched a new, advanced DigiMag digital differential pressure gauge for filter applications. The airflow gauge can be used to replace the standard analog mechanical pressure gauges.
Differential pressure-air flow gauge
The DM-1200 digital gauge can be field-programmed to choose the air velocity, flow or pressure operations. The gauge includes a specific feature for filter applications where set points can be entered. The gauge’s display blinks when the filter becomes unclean and warns the user to clean the filter.
The DM-1200 series can be easily programmed with a menu key. Users can use the menu key to access four simplified menus. The menus offer access to engineering units, K-factor, security level, rectangular or circular duct size, filter set point, valley and peak process readings, digital damping and display update. The K-factor can be used with flow sensors and Pitot tubes.
The digital gauge provides power versatility by operating with 9-24 VDC power supply, and has an accuracy of 1% on 2" w.c range and 2% accuracy on 1" to 0.25" w.c range.
