Performance Checks
Any valves or devices controlling the flow of water through a compound meter must always be opened and closed SLOWLY to
prevent shock loads that may damage the meter’s rotor assembly
Complete the following checks to ensure that a compound meter is properly installed and operational:
• Slowly open the upstream valve to apply water pressure to the meter and check to see if there are any leaks Tighten the
flange bolts as required
• Perform a functional test of the meter Slowly open valve on downstream side of the meter to evacuate any air that may
have been trapped in the service line When air has been eliminated, increase demand flow rate by further opening the
downstream valve or valves Observe the register for correct direction of flow Continue to open the demand side valves
to a flow rate sufficient to open the valve assembly in the meter—a procedure which will start water flowing through the
turbo high-side rotor The high flow pointer will now move in the proper direction Now open all applicable service valves
• Check the flow rate to verify that the flow does not exceed the maximum continuous duty specification The rate of flow
can be quickly checked by timing the quantity registered through the meter in one minute
Reading the Recordall Registers (and Encoder)
To determine the total reading for meter, the totals for both low and high flow must be added together
1 Determine the low flow total by reading the register/encoder identified as low flow Read only the moveable
number wheels
2 From the high flow register, read both the number wheels and the sweep hand Read the number wheels first Read
only the moveable number wheels Note the position of the sweep hand, round the number down to the nearest
increment Add the reading from the number wheel and the sweep hand together
3 To determine the complete total flow, add the low flow and high flow totals together
