108 Configuring the Configurable Flowmeter Module

Sample Configuration for

Totalizer Mode

Filler Function

In the Totalizer Mode Filler function, the CFM module interfaces to a prover
and counts pulses using a Flowmeter or positive displacement meter. The
module then scales pulse count to engineering units. The CFM module also
interpolates the K-Factors between frequencies 1-12.

When using totalizer mode (with prover or fill function), you may apply a
K-factor as a function of frequency, as shown below.

This section offers a sample configuration to configure your CFM module for
totalizer mode prover function. In this configuration, channel 0 is configured
and channel 1 is left unused. For a detailed explanation of the features available
in this mode, see

page 50

.

Follow the steps below to configure your CFM module for totalizer mode filler
function.

1. Create a new module, see

page 80

.

2. Set all communications options, including:

 name
 communication format
 slot number
 minor revision
 electronic keying
 RPI - For this application, the minimum RPI = 5 ms
