The New digital display flow meter is a 2 wire loop powered 4-20mA DC indicator that displays a flow rate and total. On-screen engineering units are easily configured. Password protection and 16 bit A/D resolution. A New built in wet/wet differential pressure sensor is protected by an isolated stainless steel diaphragm and provides a 4-20mA DC signal to the display. The enclosure is IP67 / NEMA 4X rated which further enhances this models capability. Available in threaded or flanged connection and bronze or stainless steel construction.
