    Series U44 Instruction Manual Conditions Upstream Straight Run Downstream Straight Run General Conditions Elbow Partially Open Valve Reduced Pipe Expanded Pipe ⚫ On the horizontal pipe, the transducer should be mounted on the 9 o’clock and 3 o’clock positions of the pipe, avoiding the positions of 6 o’clock and 12 o’clock, in case of signal attenuation caused by the pipe, sediment at the bottom, or bubble cavitation on the pipe.

  • Page 13: Method

    Series U44 Instruction Manual 2.3.4 V Method The V method is considered the standard method. It is convenient to use, but still requires proper installation of the transducers, contact on the pipe at the centerline, and equal spacing on either side of the centerline. This is recommended for carbon steel pipes.

  • Page 14: W Method

    Series U44 Instruction Manual 2.3.5 W Method The signal transmitted in a W method may be stronger than with the V method on smaller diameter pipes. This method is recommended for pipes with diameters of 3 inches (75 mm) and below or PVC pipes. Side view Section Top View...

  • Page 15: Z Method

    Series U44 Instruction Manual 2.3.6 Z Method The signal transmitted in a Z method installation has less attenuation than a signal transmitted with the V or W methods. When pipes are too large, there is some suspended solid in the fluid or the scaling and liner are too thick. This is why the Z method utilizes a directly transmitted (rather than reflected) signaling which transverses the liquid only once.

  • Page 18: Method

    Series U44 Instruction Manual 2.4.3 V Method The V method is considered as the standard method. It is convenient to use, but still requires proper installation of the transducers, contact on the pipe at the pipe’s centerline, and equal spacing on either side of the centerline.

  • Page 19: Signal Quality (Q Value)

    Series U44 Instruction Manual Adjust the transducer to the best position and check to ensure that enough sonic coupling compound was applied during installation to obtain the maximum signal strength. The system normally requires a signal strength over 75.0, which is detected from both upstream and downstream directions.
  • Page 20 Series U44 Instruction Manual transducer is mounted at the pipe’s centerline on the same diameter. Pay special attention to pipes formed by steel rolls (pipe with seams), since such pipe is always irregular. If the signal strength is always displayed as 0.00, that means there is no signal detected. Thus, it is necessary to check that the parameters (including all the pipe parameters) have been entered accurately.
