INTRODUCTION
Overview
The digital owmeter has a 4-digit LED display with daylight bright digits 0.56
inch high. The meter electronics are self-contained and all program features are accessed
via pushbutton switches on the front of the display module.
The owmeter communicates with other display modules over a datalink. This
technology allows for remote displays, the display of ow rate through multiple discharges
(summing), and the totalization of ow for multiple discharges (accumulation). Flow
rate information is provided by a paddlewheel type ow sensor mounted in the discharge.
This information is processed and shown on the digital display.
There are two operator-selectable modes; display module identication and program
access. In the display module identication mode, the digital display shows the module
serial number, manufactured date, software revision, module function, and ID number.
In the program access mode the display shows program options and operator input
selections. Operator-selected modes are accessed and selections are made using two
pushbutton switches on the front of the display module.
All controls and indicators are located on the front of the display module. Controls
are simple pushbuttons.
