When the above conditions are satisfied, slacken the lock nut by 1-½ to 2 turns, sufficient for the
sensor to be rocked. (If necessary, jolt the meter loose with a blow of the hand to the amplifier
housing.) This will allow the seal between the sensor and the chamber retro-fit kit to be broken. Do
not slacken the lock nut further unless the seal is broken and the sensor is definitely loose in the
fitting.
Note: If the system is still pressurized, the meter may lift and be held against the retaining nut.
Rocking and alternately pushing the sensor in and out of the pocket within the limits allowed by the
slackened nut will break any seal and allow oil under pressure to seep past the lock nut. If this
leakage is excessive, re-tighten the lock nut and take further action to de-pressurize the system.
When the meter can be rocked in the flow chamber and there is no serious or continuous escape of oil,
it is safe to remove the lock nut.
Always keep all parts of your body away from the axis of the sensor (i.e., the direction in which the
sensor will be withdrawn). If the system is under pressure or suddenly comes under pressure (e.g., due
to valve failure or pump start), and the lock nut is not in place, the instrument may be forcibly ejected
from the flow chamber and cause serious injury.
Clean and maintain the meter as directed and then refit it, as described in Section 2.5.
