1. 3 4 Noise detection at metallic fittings The testrod point detects leak noise at a fitting water meter valve hydrant etc Depending on the pipeline material for example plastic or metal the frequencies picked up differ significantly Therefore the frequency band for this method is wider than the frequency band for the above surface noise pick up method RD545 Operation Manual 9 Section 4 Searching for leaks You need a systematic approach when locating a leakage in a water pipeline Before attempting to locate the leak it s advised that you first trace the path of the pipeline Then you must locate the general area of the pipe where the leak is located Finally you must pinpoint the leak s location With a systematic approach the complete length of the pipeline must be checked until the leakage is detected 4 1 Locating the leakage area testrod Use the testrod to check any accessible contact points along the pipe The operator must ensure that the noises received are the result of a leakage muffled sound rather than the result of stopper neckings high sound Both sounds are useful when determining the general area of a leakage Note that flow noises can also be generated by regular discharges Figure 5 shows how the leakage area can be narrowed by accessing the measurement data of the contact spot of the particular pipeline The example below shows the highest figures between the measurement points 3 and 42.

Therefore the leakage must be located between these two contact spots When narrowing a leakage the operator has to make sure that no measurement data exceeds the scale range so that the maximum value can be identified If a measurement point shows a full scale reflection re adjust the display with the control knob 3 or the adjusting knob 1 e g up to 50 so that an increase in reflection is visible In the case of a reduced reflection the pipeline section concerned has to be checked again in order to identify the actual increase and decrease of the volume and thus to identify the two maximum values The measurement data memory has proved to be an enormous advantage as the last data is at the user s disposal until the next measurement procedure starts The pipeline section with the highest noise intensity can be determined if the adjustments of the RD545 are not changed The following above surface leakage detection procedure then has to be carried out on the particular pipeline section 10 RD545 Operation Manual Leckort x Pkt 2 xX aa gt gt bd be Pkt x Pkt 3 Leckort leakage spot Figure 5 Locating leaks with the testrod RD545 Operation Manual 11 4 2 Pinpointing leaks If the testrod has located a leak noise you can apply the ground microphone to pinpoint the leak When moving the ground microphone equipment the operator must ensure that the sounding points are sufficiently close to each other otherwise the operat
