Operating Procedure
The eFlo system is equipped with a flow rate alarm (high and low), flow rate totalizer, and
integrated valve control. The unit can be operated in either manual or automatic mode for flow
rate control. This section of the manual provides an explanation of how the unit is operated:
valve control modes, flow limit control, flow alarming, flow totalizing, and programming of the
unit.
IMPORTANT!
For best long term results, it is recommended that pressure be maintained on the flow meter at
all times. Pressure can be maintained when the shut off solenoid/valve is downstream from the
outlet of the meter. This will ensure long term calibration and accuracy.
Figure 3 shows the layout of the flow control panel on the eFlo unit. An explanation of the
panel’s components is provided as well. The panel layout will be referenced further in this
section.
