    3.3.2 Z-path (transmission) and V-path (reflection) methods With ultrasonic flowmeters, depending on the propagation route of the ultrasonic waves, the measurement methods can be divided into Z-path method (the transmission method) and V-path method (the reflection method) as shown in Fig. 3.3.2-1. Since the above explanation of measurement principles used the transmission method, the reflection method will be explained here.

    3.5 FAQ 3.5.1 Measurement method 1.1 What is ultrasonic? Ultrasonic refers to acoustic waves or vibrations of a frequency beyond the range of human hearing (generally above 20,000 Hz). 1.2 At what frequencies do ultrasonic flowmeters operate? The frequency generally utilized is several 100 kHz up to several MHz. 1.3 Why are such high frequencies used? Frequencies in the normal range (i.e.
  • Page 209 As flow velocity “V” can be determined by measuring ∆t, you can calculate the volume of flow through a pipe or open channel by multiplying ∆t by the cross sectional area of the pipe or open channel. In such calculations, it is necessary to employ a flow volume compensation coefficient with the measured flow velocity “V”...

    3.5.2 Measured fluids 2.1 Measured fluids In principle, any liquid, which allows stable propagation of ultrasonic pulse, can be measured. However in liquids where large amounts of air bubbles or solid particles are present, problems such as mis-measurements or non-measurable conditions may occur. As high temperature and high pressure liquids (oil, etc.) cannot be described categorically, consult Manufacturer when measuring such liquids.

    2.5 Can waste water be measured? From the standpoint of turbidity, there are no problems with measuring waste water inflows or discharges. However pipe conditions in selecting measurement location should be carefully considered as air bubbles are apt to be generated when there are drops or when measuring locations are directly aft of pump discharge outlets.

    3.4 Are there problems with lining detachment from the pipe interior? Centrifugal force is generally used to bond linings to the interior of pipes and during operation and the pressure of the water also acts on the lining, so problems with lining detachments are few. Should such problem occur however, as long as the sensors are not positioned directly at that point, there should be no adverse affect on measurements.

The applicable diameters for the V-path method depends on pipe material but is generally less than DN2000mm. See Chapter 3.3.2 for more detail on the through Z-path method and V-path method.

    3.6.2 Measurement The following is a description of some general problems and remedies relating to measurement. If the steps shown in this section cannot solve a problem, contact with the nearest representative. (1) Pipes which cannot be measured • Asbestos If the pipe surface is sufficiently wet, measurements can be made in some cases, but generally it is difficult with this pipe material.
  • Page 217 (3) Given measurement accuracy cannot be obtained • Incorrect site condition Check pipe specification. • Insufficient straight pipe length Required straight pipe length may vary according to changes in pipe conditions forward and backward of the measurement position (merged or separating flows, presence of valve, etc.). Refer to Chapter “1.2.5 Selection of transducer setup position (p.1-26)”.
