Loop-Powered Meters with Advanced Display Features and Control Options VantageView+ loop-powered meters are designed to operate in harsh environments and display 4-20 mA signals with ease. They feature a dual-line display, typically used to show the process variable on the 5-character top line and units or a tag on the 8-character bottom line. Certain models feature a level display in feet and inches on the top line, while the bottom line displays a custom message or tag. The meters also have a 20-segment bargraph for added display enhancement.
The meters are equipped with four CapTouch buttons for operation without removing the cover. These buttons have normal and delayed modes and can be disabled for security using a switch on the display module.
Both open collector outputs and digital input are included in all models, with options for two solid-state relays and isolated 4-20 mA analog output. The open collector outputs can be used for alarm indication, while the digital input can perform functions such as acknowledging relays and controlling timers and stopwatches. The relays can be programmed for alarm indication, on/off control, or pump alternation.
Users can access free MeterView XL software via a micro USB cable for programming and setting up the meters. This software simplifies programming and allows for saved configuration files. The meter can be powered through the USB connection during programming, eliminating the need for additional power.
