AMCO Water Metering Systems For Potable Cold Water Meters

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)

2. Encoder Electronic Meter Read (EMR)

3. InsideR™

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.
