Reflex Level Gauge Maintenance Manual

Page view
[Abstract]:
Level gauges must be installed in accordance with the Installation, Operation and Maintenance Manual.
The installation, operation and maintenance should only be carried out by qualified personnel. Ensure that all connecting pieces are tightened on assembly and after carrying out maintenance.

SERVICE MAINTENANCE

After the level gauge is first put into service, or after change of glasses, once the level gauge has reached its normal operating temperature and pressure, carefully compress the glass joints by following up the tightening bolts working at opposite sides alternately. THIS MUST BE REPEATED SEVERAL TIMES WITHIN THE FIRST HOURS, and in case any sign of leaks should appear.

If perfect sealing cannot be obtained in this way, it will be necessary to replace the joints and eventually the glass too.

DISMANTLING

Shut off the cocks and remove the level gauge body from the cocks.

Loosen and take out the tightening bolts and remove all component pieces.

Clean the sealing and cushion surface very carefully, making sure that they are clean of any remnants of joints.

Smear the threads with a thin layer of graphitised grease

REASSEMBLING

Fit in new glasses with new joints (never re-use joints which have already been in service!).

Reassemble all the other components in the right sequence and tighten the bolts thoroughly.

Never grip the level gauge body in a vice during the reassembling, but put it on a plane surface.

Never use adhesive or hermetic mastics. Remember that all surfaces must be perfectly clean.

SPARE PARTS

When ordering spare parts, please state:

type and size of the level gauge

Item number of the spare part, as shown in the above list

construction material

As regards reflex glasses and their joints, remember that each level gauge is fitted with one reflex glasses type “B” (section 34x17 mm) the size of which suits the gauge body.

 

Note: The models shown are typical examples for the maintenance of our level gauges.
