Installation & Operation Manual

e . Tighten the meter connections . Note the instructions on packaging from connection assembly when tightening .

f . To relieve any possible strain on the facility piping that might be caused by the weight of any of the large size

meters, consider incorporating a meter support under the housing of the meter .

To ensure that the meter has been properly installed and is operational:

1 . Slowly open the upstream valve to apply fluid pressure to the meter . Check the connections for any possible leakage .

Retighten the connections as required .

2 . Perform a functional test of the meter following

"Calibration Check and Adjustment" on page 8

.

GENERAL OPERATING INSTRUCTIONS

In general, the operation of a Model RCDL disc meter is either manually controlled or accessory controlled . Manual operation

applies to the applications employing hand-operated valves or other manually activated, flow-regulating devices that are not

functionally controlled by a meter accessory . Accessory controlled operation applies to applications when a meter accessory

provides a signal output to activate and/or deactivate a valve or other flow control device .

VALVES CONTROLLING THE FLUID FLOW THROUGH THE METER SHOULD BE OPENED AND CLOSED SLOWLY TO PRE-

VENT SHOCK LOADS THAT MAY DAMAGE THE METER MEASURING ELEMENT.

Manual Operation

The following procedures are for use in simple metering applications where the flow of fluid is controlled by hand-operated

valves located upstream and downstream of the meter .

1 . Slowly open the upstream valve to apply fluid to the meter .
2 . Slowly open the downstream valve to initiate the metering operation .
3 . Adjust the downstream valve so the flow rate of the fluid does not exceed the maximum continuous flow rate

specification of the meter .

NOTE:

N

On meters with an accessory device providing a totalizing indicator, the flow rate of the fluid can be checked by

timing the number of gallons registered in one minute .

4 . To stop metering, slowly close the downstream valve; then close the upstream valve .

Accessory Controlled Operation

Operating procedures for accessory controlled applications are dependent on the specific function of that accessory

employed and its electrical interconnection with a flow control device or devices . Refer to the bulletin or bulletins covering

the applicable accessories for specific operating instructions (included as a supplement to this manual when required .)

Shutdown Instructions

If the meter is to be shut down for an extended period of time, first flush out the measuring chamber of the meter to prevent

the settling out of undissolved solids or the accumulation of corrosive deposits .
