Mounting Supplies
The following items will be needed to mount the sensors:
● Mounting Frames or Mounting tracks
● Tape, chalk and a ruler or measuring tape
● Spacer Bar
● Mounting Guide (for Direct Mount)
● Ultrasonic coupling compound and/or coupling pads
● Sensors (matched set)
Selecting a location for the sensors
1. Locate the sensors downstream from the center of the longest available straight run. A
2. Do not, if possible, install the sensors downstream from a throttling valve, a mixing tank,
3. Avoid mounting the sensors on a section of pipe with any external scale. Remove all scale,
4. Do not mount the sensors on a surface aberration (pipe seam, etc.)
5. Do not mount sensors from different ultrasonic flow meters on the same pipe. Also, do not
