EMO-500
Operation and Programming Manual

Product Description
For use in steady or pulsing streams, the EMO-500’s primary purpose is to monitor the flow rates of two
flow meters, measuring flow rates, comparing totals, and verifying the ratio of flow A to flow B. You can
also wire an alarm to the EMO-500 so it can alert you to fluctuations from normal.
The unit comes from the factory with default values already programmed. However, if programming
parameters require change, you can input data from the front keypad; you can also do this from a
computer.
You can “Quick Program” the EMO-500, or take advantage of the Full Programming option. Program
keys are in red on the unit’s keyboard (some keys have a dual function). You can also program the EMO-
500 through the unit’s serial port. As a security measure, you can block access to programming when in
the Full and Serial Port programming modes.

Principle of Operation
After you connect two flow meters to the unit and power it up, the EMO-500 can begin monitoring flow,
totals, and ratios. Monitor data on-screen; fine tune and adjust programming parameters as needed.
