Sono-Trak™ Doppler Ultrasonic Flow Meter
Sono-Trak Transit Time Ultrasonic Flow Meters
In the event the flow to be measured does not contain the minimum required particle
size and/or parts per million count, and the transducer will not read, you may want to
consider the Sono-Trak™ Transit Time ultrasonic flow meter for your application.
Contact an EMCO sales representative with your flow meter application questions.
See “EMCO Flow Systems Support” on page 3-11 for contact information.
INSTALLATION PROCEDURES
After you have performed the pre-install check and determined that the Doppler flow
meter will work for your application, follow these steps to install your meter.
To Install the Sono-Trak™ Doppler Ultrasonic Flow Meter:
1. Mount and connect the transducers (see page 2-9)
2. Mount and connect power to the electronics enclosure (see page 2-13)
3. Turn on power to the electronics enclosure using the switch on the display panel
and follow display panel for meter set up (see “Operation” on page 2-15 for more
information on configuring your meter for operation)
Mounting and Connecting the Transducers
The clamp-on transducers are NEMA 6-rated and fully submersible. However, if your
system requires that the transducers and the digitizer be continuously submerged, they
need to be specially encapsulated to prevent corrosion. Contact “EMCO Flow
Systems Support” on page 3-11 for information on configuring your flow meter
components for continuous submersion.
To Mount the Clamp-On Transducers to the Pipe:
1. Ensure the pipe surface is clean. Use sandpaper to remove all paint and scale from
the pipe surface if necessary.
2. Apply sonic gel to the transducer lenses. For best results in most weather
conditions and heat, use Dow Corning
®
High Vacuum Grease or the supplied
Novagard
®
grease G661™.
Attention:
Always apply sonic gel to the transducer lenses before placing on the
pipe. The sonic gel must be used to transmit the energy from the
transducer crystals through the pipe wall and into the flow to be
measured.
