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
location ten pipe diameters or greater downstream from the nearest bend will provide the
best flow profile conditions.
2. Do not, if possible, install the sensors downstream from a throttling valve, a mixing tank,
the discharge of a positive displacement pump or any other equipment that could possibly
aerate the liquid. The best location will be as free as possible from flow disturbances,
vibration, sources of heat, noise, or radiated energy.
3. Avoid mounting the sensors on a section of pipe with any external scale. Remove all scale,
rust, loose paint, etc., from the location.
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
run the sensor cables in common bundles with cables from communication equipment,
other Siemens systems, or any type of ultrasonic equipment. You can run these cables
through a common conduit ONLY if they originate at the same flowmeter.
