Keypad Operating Procedure
|
IMPORTANT!
See Appendix 3 for recommended startup procedures involving Zero Tare, Max Tare, and Altitude Adjustment. Following these procedures will provide optimal accuracy and control.
|
The eFlo system is equipped with a pressure and 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 the basic menu navigation through the keypad as well as how the unit is operates including: 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.
