Chapter 3 Operating Instructions

After installing the Innova-Mass Vortex Flow Meter, you are ready to begin operation. The sections in this chapter explain the display/keypad commands, meter start-up and programming. The meter is ready to operate at start up without any special pro- gramming. To enter parameters and system settings unique to your operation, see the following pages for instructions on using the setup menus.

Flow Meter Display/Keypad

The flow meter’s digital electronics allow you to set, adjust and monitor system parameters and performance. A full range of commands are available through the display/keypad. The LCD display gives 2 x 16 characters for flow monitoring and pro- gramming. The six push-buttons can be operated with the enclo- sure cover removed. Or, the explosion-proof cover can remain in place and the keypad operated with a hand-held magnet posi- tioned at the side of the enclosure as shown in the illustration at the left.
