OPERATION
General Operating Instructions
REGARDLESS OF THE OPERATING PROCEDURE USED, THE VALVES OR DEVICES CONTROLLING THE FLOW OF LIQUID
THROUGH THE TURBO METER MUST ALWAYS BE OPENED AND CLOSED SLOWLY OR IN STAGES TO PREVENT SHOCK
LOADS THAT MAY DAMAGE THE METER'S ROTOR ASSEMBLY.
Manual Operation
These procedures are intended for use in simple metering applications where the flow of liquid through the meter is
controlled by hand-operated valves located in the facility piping upstream and downstream of the meter.
1. Slowly open the upstream valve; apply liquid to meter.
2. Slowly open the downstream valve to initiate metering.
3. Adjust the downstream valve so that the rate of ow does not exceed the maximum continuous ow rate specication of
the meter.
4. To stop metering, slowly close the downstream valve, then close the upstream valve.
Accessory Controlled Operation
The step-by-step operating procedures used in accessory controlled metering applications are dependent on the specific
function of the meter-accessory employed and its electrical or pneumatic interconnection with the flow control device or
devices. Refer to the IOM manuals covering the applicable accessories for specific operating instructions.
Shutdown Instructions
If the turbo meter is to be shutdown for an extended period of time, it is recommended that the measuring chamber be
thoroughly flushed to prevent the settling out of undissolved solids or the accumulation of corrosive deposits.
