• Remove deposit from bonnet stopper, if any,
• Remove deposit from torque arm pin or lower face on torque arm pin (contact
face), if any,
~Note If accumulation of deposit makes the distance between bonnet stopper
and lower surface of torque arm (contact surface) too short, they may
contact before liquid level becomes zero, resulting in unsatisfactory
accuracy (linearity).
Float
• Remove deposit from the surface of float, if any.
~Note
If weight or dimension of float changes, measured accuracy (zero, span)
will be affected.
• If float is corroded, its replacement is recommended.
Chamber
• Remove sedimentation from the bottom of chamber, if any,
• Steam clean or chemically cleanse inside of chamber if there is any deposit on the
side of chamber.
~Note If accumulation of deposit makes distance between chamber and float too
short, they may contact during operation, resulting in reduced accuracy
(zero, span or linearity)
