The Precision Digital VantageView+ loop-powered flow rate/totalizer provides clear and accurate display of any 4-20 mA signals. Its dual-line display showcases flow rate on the top display and flow totals, grand totals or tags on the bottom display. The display uses 12-segment characters on the top and 14-segment characters on the bottom for clear viewing. The display also features a 20-segment bargraph for a visual representation of flow data.
This device is user-friendly with its CapTouch through-window buttons, which allow for operation without removing the cover. The buttons have two modes of operation and can be disabled for security. The device also features two open collector outputs for alarm indication or pulse output and a digital input for remote reset and other functions. Some models come equipped with two solid-state relays and an isolated 4-20 mA analog output.
Setting up and programming the device is made easy with the included PC-based MeterView XL software, which connects via a micro USB cable. This software simplifies the programming process and saves configuration files for future use. The USB connection also powers the device during programming.

Except where noted all specifications apply to operation at +25°C.
