Figure 13: Fixed Output Source
This option allows the user to select a constant mA value the MX 9000 will output regardless of any
changing values. A constant mA signal could be used as an external indicator showing if the MX 9000 is
on. Allowable values are from 2mA to 20mA.

Figure 14: Rate A or B Source
RATE source allows the user to configure the mA output to represent the flow rate value. The analog
output span can be scaled for either zero to max flow or a non-zero flow to max flow. If the flow rate
goes above the programmed maximum flow rate, the analog output will continue to increase, up to a
maximum of 22mA. This is useful for system fault detection.
Min Flow Rate
Enter the minimum user flow rate. This can be a non-zero value, such as the lowest application flow
rate if the equipment monitoring the mA signal can be programmed as such. It can also be entered as
zero, but in this case it will affect the accuracy of the mA reading vs flow accuracy. If a non-zero value is
entered, the user will also be asked to enter a mA value to represent zero flow.
Min Flow mA
Enter the mA to represent the above entered minimum flow rate. Value must be equal to or greater
than 2mA.
Max Flow Rate
Enter the maximum flow rate to monitor.
Max Flow mA
Enter the mA value to represent the above entered maximum flow rate value. 20mA is the maximum
allowable value.
Zero Flow mA
This screen only shows if the Min Flow Rate was programmed as a non-zero value. Enter the mA value
to represent zero flow. Lowest value allowable is 2mA (cannot be greater than the Min Flow mA value).
