Pump alternation control
Relay Reset: User selectable via front panel buttons or PC
Automatic reset only (non-latching)
Automatic plus manual reset at any time (non-latching)

MeterView® for Trident
MeterView software allows remote programming and data acquisition of the Trident series. The remote programming allows for all available meter settings to be programmed from a personal computer through an easy user-friendly interface. The data acquisition allows the user to gather readings from up to 100 meters at user-selected intervals and generate charts using common tools like Microsoft® Excel.
Digital Panel Meters make a great front end to a PC-based data acquisition system. They are easy to set up, can be used for a wide range of inputs, will power the transmitter, and best of all provide a local display of the process. Precision Digital has the perfect package with its Trident Digital Panel Meters, a wide selection of serial adapters and converters and free MeterView software. Data is displayed on the PC and written to a file that could then be imported into a spreadsheet or other application.
Data Logging up to 100 Trident Meters
Sample File Generated by MeterView®
Great for tank level monitoring!
