AMCO Water Metering Systems For Potable Cold Water Meters
Installation/Start-up Instructions
INTRODUCTION
All AMCO water meters have been manufactured with current technology in
accordance with applicable AWWA standards. Water passes through a measuring
chamber driving an oscillating piston or rotor, the movements of which are transferred
by appropriate gearing and magnetic drive to a standard direct reading sealed register.
If the meter has been ordered with visual remote (RMR), electronic remote (EMR) or
InsideR™ transmitter, refer to the following documents for additional instructions:
1. Remote Meter Read (RMR) RMR-INS-022
2. Encoder Electronic Meter Read (EMR) EMR-INS-026
3. InsideR™ INS-INSIDE-RF
TESTING FOR METER ACCURACY
All AMCO water meters have been flow tested before shipment. Should further
accuracy tests be necessary, the requirements of Table 5-3 of the AWWA Manual M-6
should be followed. Before testing, thoroughly flush the meter to eliminate all air from
the test bench system. In the case of turbine and compound meters, water should
pass through as much straight pipe as possible before entering the meter, or install a
turbulence canceling strainer ahead of the meter. Turbines and compound meters
tested in series must have straight pipe between meters for absolute accuracy testing.
GENERAL INSTALLATION INSTRUCTIONS FOR ALL AMCO WATER METERS
(1) Install meters in a service line which has been flushed free of foreign
material.
(2) Install meters in horizontal or inclined pipe work.
(3) Install meters with the flow direction arrow pointing downstream, i.e. towards
the utility customer’s facility being served by the meter.
(4) Thoroughly tighten all meter couplings or companion flange bolts.
POSITIVE DISPLACEMENT AND TURBINE METER START-UP
A meter’s measuring device can be damaged if subjected to full flow conditions prior to
expelling all the air from the pipeline.
(5) With all valves closed, open a downstream faucet or other fixture that will
demand water from the water main.
