Installing wafer-style sensors
A wafer-style sensor, which has no flanges or fittings, lets you “clamp” the sensor between process
connections in the pipeline. Model CMF025, CMF050, and CMF100 sensors are available in the wafer style.
A wafer installation kit is shipped with a wafer-style sensor. A wafer kit contains the following pieces:
• 4 flange bolts
• 8 flange nuts
• 2 alignment rings, which help center the sensor between the bolts
To install a wafer-type sensor, refer to Figures 12 and 13 and follow the steps below:
1. Make sure the bolts provided in the wafer installation kit are rated for your process connection.
2. Slip the sensor alignment rings over each end of the sensor wafer, then insert the sensor between the
process connections in the pipeline (Figure 12). Installing gaskets is recommended. (Micro Motion
does not supply gaskets.)
3. Insert the bolts through both process connections, and thread the nuts onto the bolts. Tighten nuts as
tight as you can with your fingers.
4. Rotate the sensor alignment rings in the direction that pushes the bolts outward (Figure 13). Rotate
both rings until the assembly is centered and tight.
5. With a wrench, tighten nuts in an alternating order, to ensure the process connections are evenly
tightened.
