3.3 PREPARING TO MOUNT THE TRANSDUCERS
Installing the transducers is fairly straightforward. However, careful planning will avoid any snags that
may delay the installation. Previously, based on the input you fed into the meter’s computer, it had
recommended the transducers size, mounting option and spacing. With the transducers at hand, we are
now ready to mount them. But first, some very important preliminary work must be done which consists
of:
z
Selecting a mounting option for your application
z
Selecting a location on the pipe
z
Preparing the pipe to accept the transducers
NOTE: When installing transducers, do not key in the V/M (Version/Modification) label number
as the Transducer Size.
3.3.1 HOW TO IDENTIFY 1011 TRANSDUCERS AND MOUNTING HARDWARE
1011 series of universal transducers and mounting frames have the following color-codes for easy
identification:
GOLD ....................... SIZE ‘A’ GREEN…………………SIZE ‘D’
BLUE ........................ SIZE ‘B’ BLACK…………………SIZE ‘E’
RED .......................... SIZE ‘C’
The transducer part number located on the front face provides a more detailed identification.
For example, the Part Number: 1011PPS-C2 means:
3.3.2 SELECTING A LOCATION FOR CLAMP- ON TRANSDUCERS
z
Locate the transducers 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.
z
Do not (if possible) install the transducers 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.
z
Avoid mounting the transducers on a section of pipe with any external scale. Remove all scale, rust,
loose paint, etc., from the location.
