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 Subgroup (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.
