3. HARDWARE INSTALLATION GUIDE
3.1 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 impor-
tant preliminary work must be done which consists of:
• Selecting a mounting option for your application
• Selecting a location on the pipe
• 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.
3.1.1 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:
3.1.2 SELECTING A LOCATION FOR CLAMP-ON TRANSDUCERS
• 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.
• 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 distur-
bances, vibration, sources of heat, noise, or radiated energy.
