PART 2 - TRANSDUCER INSTALLATION
6. Place the upstream transducer in position and secure with a
stainless steel strap or other. Straps should be placed in the
arched groove on the end of the transducer. A screw is provided
to help hold the transducer onto the strap. Verify that the
transducer is true to the pipe—adjust as necessary. Tighten
transducer strap securely. Larger pipes may require more than
one strap to reach the circumference of the pipe.
7. Place the downstream transducer on the pipe at the calculated
transducer spacing. See Figure 2.13 . Using firm hand pressure,
slowly move the transducer both towards and away from the
upstream transducer while observing Signal Strength. Clamp the
transducer at the position where the highest Signal Strength is
observed. Signal Strength of between 7 and 100 is acceptable.
On certain pipes, a slight twist to the transducer may cause
signal strength to rise to acceptable levels.
8. Certain pipe and liquid characteristics may cause Signal
Strength to rise to greater than 100. The problem with operating
a TFXL with very high Signal Strength is that the signals may
saturate the input amplifiers and cause erratic readings. To
decrease the Signal Strength one transducer can be offset
radially, as illustrated in
Figure 2.4 on page 2.10, or a V-Mount
transducer mounting method may be chosen.
9. Secure the transducer with a stainless steel strap or other.
