5.5 Sensor Installation

5.5.1 Preliminary Installation Procedures

Reflect and Direct Sensor Mounting Reflect and Direct mounting modes are supported for clamp-on sensors. The flow meter recommends a mounting mode after analyzing your pipe and liquid data entries.

Note

When installing sensors, do not key in the V/M (Version/Modification) label number as the Sensor Size.

full pipe.

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 provideadequate 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 rad

3. Avoid mounting the sensors on a section of pipe with any external scale. Remove allscale, 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 other instrumentation.You can run these cables through a common conduit ONLY if they originate at the sameflow meter.

6. Never mount sensors under water, unless you order submersible units and you installthem in accordance with factory instructions.

7. Avoid mounting sensors on the top or bottom of a horizontal pipe. The best placement on a horizontal pipe is either the ten oclock and two oclock position for Reflect Mode, or one sensor at nine oclock and one sensor at three oclock for Direct Mode. Mounting a vertical pipe is recommended only if flow is in the upward direction. When mounting ona vertical pipe flowing in a downward direction make sure there is sufficient back pressure in the system to maintain a

Preparing the Pipe 1. Pick a mounting location with the longest straight run. You must have easy access to at

least one side of your pipe. The pipe at the mounting location must remain full, even atzero flow.

2. Decide on your mounting mode (Direct or Reflect). Always use Reflect Mode whenever

possible. You may only need to use Direct Mode if your pipe is plastic.

3. After receiving the spacing dimensions from the Installation Menu, prepare the pipesurface. De-grease the surface, if necessary, and remove any grit, corrosion, rust, loosepaint, etc. Use abrasive material provided to provide a clean contact surface for thesensors.

Note Please note that the instructions show vertical mounting for clarity purposes only. Do not install sensors on the top of a pipe.

4. Clean an area 13 mm (1/2-inch) on either side of the sensors. 5. Clean an additional 13 mm (1/2-inch) along the length of the sensors.
