™
"PT" Meters are fitted with flange protectors to seal off the inside diameter. All
meters are carefully boxed or crated for protection during delivery. In some cases, meters
can be bolted into the tubes on request, but this method is not recommended. There is an
extra charge for export crating
4.2 Service and storage
Periodic servicing of the “PT” Meter is desirable to maintain optimum measurement
performance.
1.
Keep meter clean and free from foreign matter externally and internally.
2. Check freedom of motor rotation.
3. Rotor should be free to move laterally along the shaft from thrust washer to thrust
washer.
4. Keep pickup coil and cable connections dry, clean and in good condition.
It is not necessary to disassemble meter for cleaning during normal service conditions
unless it is suspected of malfunction or if operational service is discontinued for an
extended period of time. The method of cleaning depends on the fluid being measured. It
is at the discretion of the operator to adopt the most suitable cleaning operation, with
consideration given to the materials of which the meter and its parts are made.
Steam must not be used , nor should a higher flow rate than that stipulated for the meter be
applied during in-line cleaning processes.
To store the meter, stand it on one end flange with both end flanges and pickup coil
covered to protect against foreign matter and temperature extremes. In damp storage
areas, damp-proof packaging with silica gel desiccants is recommended.
