The Vantageview PD6720 is a plastic, field-mounted, loop-powered flow rate/totalizer that can display flow rate and total from an analog output (4-20 mA) flowmeter. The fact that this meter is loop-powered means that there is no need to run additional, costly power lines. The display has a five digit upper display for rate, a seven alpha-numeric character lower display for total, and comes standard with a backlight. The PD6720 is built in a NEMA 4X and IP65 rated plastic enclosure which can stand up to even the harshest environmental conditions. Two features that really make it stand out are a wide viewing angle display and SafeTouch® through-window buttons. These buttons allow the PD6720 to be programmed and operated through the cover window, thus eliminating the need to remove the cover in dirty or wet environments.
