PHYSICAL WATER LEAK DETECTION DEVICES

MAIN CAUSES OF PHYSICAL WATER LEAK:

* High Water Pressure

* Poor quality of pipe material

* Small pipe diameter

* Poor workmanship on fittings

* Rotting of the pipe by aging

* Soil features and collapses

* Heavy traffic load

* Water quality

* Various repair activities

* Carelessly made meter and service connections

* Abandoned links.

WORKING PRINCIPLE:

Physical water leaks in the world are generally made by using acoustic listening method by listening to the vibrations and vibrations on the pipe with sensitive microphones. Technological developments have provided convenience in water leak detection as in many sectors.

WHERE TO USE:

After testing in all city networks with water at a certain pressure, indoor installations, heating installations, natural gas and oil lines, if there is a leak, it can be listened to by giving pressurized water into the line.

WHY USED:

When there is a water leak, it is not possible to find where the leak is. It is necessary to dig every suspected spot, but even this method is not always and everywhere possible and takes a lot of time. It is not an effective method either. Here, physical water loss detection devices come into play and lead us to the leak without any excavation, allowing us to find its exact point.

RULES TO BE CONSIDERED WHEN USING ON THE FIELD:

One of the most important things we need to pay attention to is whether there is an external sound that will affect the device where we hear excessive noise and we suspect that the settings / values of the device are correct.

TIPS OF WATER LEAK DETECTION:

We need to concentrate fully on the device and we should stop working in situations that will damage our ears.

We should use different microphone feet according to the characteristics of the ground. (For example, using soil stakes on soft soils)

We cannot listen properly in noisy environments. By making the most efficient listening during the night hours when the pressure in the networks is the highest and the external noises are the least, we can reach the result with better quality and faster.

EXAMPLES:

It is one of the examples experienced today that the water escaping from the pipes hollows the ground and causes collapses, seeps into the foundations of the buildings, rots the foundations and causes the buildings to collapse.

BASIC PRINCIPLE

SEWERIN has a long tradition of manufacturing systems for the detection of damages in pipe networks through correlation SeCorr® 300 is a system of unmatched quality to complement the current product range.

The all-digital signal processor and ample sending eliminates interference that so often causes problems with traditional adapters.

It eliminates the notorious whistling in digital radio transmission routes. Even with the narrow bandwidths of analog modules there will be no more restrictions. The noises recorded from the leak are already digitized in the microphone, thus eliminating their feedback via cables. This provides distinct advantages, especially in plastic pipes, where the noise emitted from the leak, as a rule, is transmitted very little as a rule and is therefore rather quiet.

The result improves leak coverage in non-metallic piping increasingly used in water pipe networks today Can be used to analyze measurements such as laptop and desktop PCs, Tablet PCs or field laptops for example specially designed for use in adverse conditions USB Thanks to its standard, the system can be easily connected to computers.

Provided the computer is a work of art, the SeCorr® 300 system offers the user every possibility to produce optimal results even under the harsh conditions that traditional correlators would reach their limits.

TRANSMITTER UNIT

To accommodate the radio transmitter RT 300, it is mounted on a tripod, so it can achieve a transmission range of up to 1000 meters. If the range of the radio transmitter is not sufficient for successful connection, the noise is stored in the transmitter's memory for 40 minutes. It is then transmitted to the receiver as soon as the radio link is established.

Thanks to the microphone holder on the tripod, the transmitter unit can be easily transported to the field in one piece.

The user can listen to the existing noise through headphones, which allow him not only to access the level of the noise, but also to filter it. With the use of the filter it is easy to predict in which frequency range the noise is highest. The instruments are marked with a highly visible bright band that makes them easy to spot. LEDs right around the cladding ensure safety when taking connection measurements at night.

The supplied rechargeable batteries provide such a large capacity that systematic correlations well above the normal working day are not a problem.

As soon as the measurement is completed, the entire transmission unit can be transported in the vehicle.

Alternatively, the transmitter unit can be disassembled, folded down on the tripod and all parts can be put inside the bag.

RADIO RECEIVER

The RX 300 receives signals from the receiver transmitter and routes them to the PC via a USB cable. The cable can be connected to any computer with a USB port.

VIEW OF BASIC FUNCTIONS


> Database-based software, no more cumbersome searching through folders for filenames, all measurements at a glance

> Correlation on time axis with free choice of correlation segment, slope mode of synchronized data; noisy areas and noisy areas can therefore be reliably identified and hidden (e.g. consumption noisy times)

> Original noises can be saved; there is an option to create a noise archive for comparison


> Filters up to 10 bands, up to 5 filter groups;

the results of various, selective filter settings can be compared.

> Input up to 3 freely definable additives and 5 different pipe cuts; Optimal flexibility as opposed to fixed standards for correlation professionals

> Easy drawing of damage drawings to support measurement reports; optimal certification for service companies.
