Operation start

ARD 4XXX: security instructions "Mounting of the meter into the pipeline, pressure check" to be followed observed.
Put installation into operation, open valves slowly, fill pipeline network gradually
• Vent the installation well.
• Pressure shocks must be avoided in order not to damage the meter.
Inclusions of air cause measuring errors in all types of meter and in operation they may damage them.

Proceed to a check of the tightness of the connections of the unit.

Check the flow of the installation

Metering of the flow rate with the roller counter for 30...60 sec.
Establish the flowrate per hour with the formula:
Totalised volume in liters x 3600
= Liters per hour
Measuring time in seconds
Should the established value lie over and above the specification of the meter (Q ), either a flow control choke (throttle) must be inserted
max
behind the measuring unit or a bigger measuring unit must be used.

Electrical equipment and ancillaries

Check proper functioning.

In operation

Use in ships
After loading heavy oil, the flowmeter must be cleaned with light oil. Prior to blowing out the pipes, the isolating valves at each side of the
flowmeter must be closed.
