Maintenance
Periodic Recalibration
If the flowmeter is properly installed, the zero and span calibrations will require limited
attention. However, to maintain the accuracy of your flowmeter’s operation, the zero and
span should be periodically redone. The frequency of recalibration is highly dependent
upon the application in which the flowmeter is being used and the severity of its
operating conditions. Initially frequent recalibrations should be performed (noting the
deviations), then tapering off in frequency as time and experience dictate.
Refer to the
Programming
and
Calibration
sections of the integrator manual.
Checks
If material sticks to the sensing plate, incorporate a program to ensure that the
impingement area remains clean. If sticking of the material persists, contact your
Siemens Milltronics representative.
Check for material bridging across the load cell or sensing plate to the housing which can
restrict the free movement of either component.
Do not strike the flowmeter, its components, or adjacent piping to dislodge material.
Check for wearing of the sensing plate. If wear is excessive contact your Siemens
Milltronics representative.
Spare Parts
The following are the recommended spare parts. As each may be available in more than
one option, consult Siemens Milltronics for assistance in ordering spare parts. In all
correspondence please quote the Milltronics Serial Number of the unit for which the
parts are required.
