Steps to Install the Transducers:
1)
Determine an optimal location. The straight pipe at both sides of the transducers needs to be of
sufficient length
(See Section §3.1, #1). The pipes are required to be in
favorable condition
–
newer pipes with no rust are recommended (See Section §3.1, #4). Horizontal pipes typically
have gas bubbles inside, especially on the pipe ceiling. There also may be sediment on the pipe
base. As a result, it is recommended that the transducers are installed on the side of, rather than
the top or bottom of, a horizontal pipe. See Appendix §9.2 for more details.
2)
Make sure the chosen location is safe for and compatible with the operation of the flow meter.
The RH40 is not designed for contact with hazardous materials.
3)
Clean any dust and/or rust off the spot where the transducers are to be installed. For better results,
polishing the pipe’s outer surface with a sander is strongly recommended.
4)
Extra care should be taken to avoid any sand or dust particles left between the pipe surface and
the transducer surface. We recommend wiping the surface thoroughly with a damp towel or
sponge. Once the surface is completely clean, dry it with a towel for best results.
5)
Apply adequate ultrasonic couplant (grease, gel, or Vaseline®)*.
Couplant should be spread
over the entire transmitting surface on the transducer and the entire installation surface on
the pipe.
Make sure there is no gap between the transducer transmitting surface and the pipe
surface. However, be careful not to apply too much couplant, especially for small pipes. See
