1.4 Recommendations for hygienic and self-

draining applications

CMFS sensors are certified EHEDG TYPE EL CLASS I for hygienic applications when installed

vertically with the process fitting and gasket combinations listed in the Position Paper of

the EHEDG Test Methods Su/jointfilesconvert/383971/bgroup (available at http://www.ehedg.org). Other process

connections/gasket combinations may be used provided they have been evaluated and

successfully tested for in-place cleanability according to the latest edition of EHEDG

Document 2. Refer to the ELITE Product Data Sheet for further information about fitting

options.

For optimal cleanability and drainability:

• If possible, install the sensor in a vertical pipeline with the process fluid flowing

upward through the sensor.

• If the sensor must be installed in a horizontal pipeline, drainage is accomplished by

air purge evacuation of the pipeline circuit.

• For clean-in-place (CIP) applications, Micro Motion recommends using the

generally-accepted flow velocity of at least 1.5 m/s for cleaning the sensor.

• The gap between the electronics housing and sensor body should be inspected

periodically. Manually clean this gap when necessary.
