4. Operating instructions
After installing the RIM20 rotor insertion flowmeter, you are ready to begin operation.
The sections in this Section explain the display/keypad commands, meter start-up and
programming.
The meter is ready to operate at start up without any special programming.
To enter parameters and system settings unique to your operation, see the following pages
for instructions on using the setup menus.
4.1 Flowmeter display/keypad
The flowmeter’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 programming.
The six push-buttons can be operated with the enclosure cover removed. Or, the explosion-
proof cover can remain in place and the keypad operated with a hand-held magnet positioned
at the side of the enclosure as shown in Figure 47.
