SeCorr 300 -Digital leak locating correlator

The SeCorr® 300 is Sewerin's new fully digital correlator offering unprecedented performance in finding water leaks even on plastic pipes and trunk mains. The fully digital signal processing and data transmission largely eliminate the limitations experienced with conventional analogue correlators. The digital radio eradicates the notorious hissing in transmission paths. The narrow bandwidth of analogue radio transmission no longer poses a restriction on transmitting water leak noise information. The noises recorded from the water leak are digitised at source, in the microphone, thus eliminating interfering feedback via the cables. This offers significant advantages, particularly when used to find water leaks on plastic pipes, where the water leak noise is, as a rule, very poorly transmitted and thus very quiet. The result is improved water leak detection in non metallic pipes, which are increasingly being used in water networks. Notebooks, Toughbooks and desktop PCs can be used to analyse the measurements. USB connections ensure the system can be easily connected to all these computers. The SeCorr® 300 system offers you the best chance of finding those difficult to locate water leaks, even under the most difficult of conditions where other conventional correlators have reached the end of their detection limits.

The Digital radio transmitter unit

The radio transmitter RT 300 is mounted on a tripod during correlation offering optimum radio performance. If the radio transmitter is out of transmission range of the base station the water leak noise is stored in the transmitter's memory and transmitted to the receiver as soon as the radio connection is re-established.

The Radio Receiver

The RX 300 receiver receives signals from the transmitter and relays them to the PC via a USB cable. The cable can be connected to any computer with a USB port. The receiver is attached to a mounting clip on the notebook's carrying strap for mobile use. The RX 300 also features a rubberised magnet for use with a measuring vehicle. This holds the receiver on the roof of the vehicle without damaging the paintwork - no need for the installation of a roof antenna. An LED control lamp continually indicates the status of the RX 300.

The Software

Overview of basic functions Database-based software, no more cumbersome searching through folders for file names, test can be seen at a glance Can also be run on 64-bit operating systems thanks to .net 2.0, future-proof Mode of curve of correlatable, synchronous data on a time axis with free selection of correlation section; loud areas and areas with interference can thus be reliably identified and hidden (e.g. times with noises of consumption) Original noises can be recorded; there is the option of creating a noise archive for comparison purposes or to allow other users work with the stored leak noises post correlation Filters of up to 10 tapes in up to 5 filter groups; the results of various, arbitrary filter settings can be compared Input up to 5 different pipe sections and up to 3 freely definable extra materials; optimal flexibility as opposed to fixed standards for correlation professionals Easy drawing of damage sketches to supplement measurement reports; optimal documentation for service companies
