Function

Sebalog N-3 is a system for acoustically monitoring pipe systems. It has Log N-3 noise level loggers and the Commander-3 as its basis. The Commander is used for programming the loggers as well as reading out and analysing the recorded measurements.

To monitor a zone, you can attach as many noise level loggers along the pipe as you wish. They then perform regular noise measurements within a certain time window. The user can set the exact measurement time window and other parameters before measuring begins. The level and frequency of the individual measurements are saved in the logger. Even the quietest noise is saved as an audio recording.

After measuring, you can collect the loggers, call up the readings and check for leak noises, and then put them back in a new zone, for example. This allows all the zones in a pipe system to be checked in succession for leaks.

However, the loggers can also be left in the same zone to monitor it permanently. The measurements from the individual loggers are then read out on site. Just approaching the installed loggers with the Commander or another reader will suffice. Wireless data transfer takes place automatically. Ideally, all you have to do is drive by where the loggers are being used.

Features

The Sebalog N-3 system has the following features:

• Loggers can be used temporarily, permanently or in the network

• Wireless communication between all components

• Audio data recorded directly in the logger

• “Commander-3” with colour display, USB port, large memory capacity, and

much more.

• Complete group/logger management without a PC

• History function

• Extended wireless range using repeater

• Logger available as TNC version with external antenna

Important and common terms

2 Important and common terms

User mode

Level and frequency

ESA value

Group mode

The Commander-3 can be operated in two different user modes (see page 23):

• Easy mode

• Professional mode

You can switch between these modes in system settings menu (see page 25).

These two values are identified each time a noise logger performs a measurement:

• “Level”

• “Frequency”

ESA stands for “Extended Spectral Analysis” and means that noise level and frequency are combined in one reading using a mathematical formula. This results in an extended view of the measured data, which makes the leak probability and position visible in relation to other loggers. The dimensionless ESA value can be between 0 and 100. The higher the ESA value, the higher the leak probability and the shorter the distance from the logger to the leak.

In order to analyse the recorded measurements, the noise loggers must be read after measuring, i.e. the data in the loggers is accessed wirelessly with a reading device (Commander/Reader/PC). It is possible to do this in the following ways:

Group mode

… is the noise level (volume) of a measurement

… is the frequency in the measurement’s frequency spectrum with

the greatest deflection

“Lift&Shift” “Patrol” “Network”

The loggers are collected; data is read out wirelessly

in the office

The method must be chosen for reading out the measured data before the measuring work is performed. Before measuring, the mode decided on is permanently assigned to the loggers or logger groups. After that, only loggers that have been configured for reading using “Patrol” can be read with “Patrol”, for example, and not with “Lift&Shift” or “Network”. The same applies to the other group modes.

The loggers remain at the place of use;

data is read out wirelessly while “driving by”

All the installed loggers are networked with each other and connected to a GSM box;

data is read out via mobile radio from the office

Important and common terms

Workgroup

Measuring window

Measuring period

Leak threshold

Leak status

Leak value

Configuration mode

The Commander can only ever interact with a single registered logger group. This group is called the “workgroup”. It is not possible to program or read loggers from another group.

The “measuring window” is the time during which a logger is programmed to carry out measurements, e.g. from 2 a.m. until 4 a.m. in the morning. A measuring window could also be referred to as a “measuring day”.

A measuring period refers to the time span that passes between programming and reading a logger. A measuring period can therefore last 1 to 100 measuring days.

There is a certain basic noise level in each pipe system. This basic noise level is referred to as the “leak threshold”. This level may be known or estimated based on experience. If the lowest measured noise level in a section of pipe is above the leak threshold, there is presumed to be a leak.

If the level of the quietest noise in a measuring window is above the previously found leak threshold (see above), the logger goes into “leak status”. This means, for example, that when this logger is read, a warning appears on the reader indicating that there is an increased probability of a leak close to the logger.

The term “leak value” combines the three measurement results – level, frequency and ESA value – determined for the quietest noise in a measuring period.

If a noise logger has been switched off (i.e. it has stood “on its head” for at least 3 minutes), it is in “configuration mode” after it is switched back on. This means:

• The previous programming has been deleted. The logger is now unprogrammed.

• Switching off has not deleted the previously saved measurement results. They are

still in the logger’s memory and can be accessed by a reading device, but only by single interrogation (see page 54).

• The logger is ready for wireless operation and waiting to be contacted by the Commander or PC.

The logger remains in configuration mode until it is reprogrammed.

Identification number

Each device in the Sebalog N-3 series has a unique serial number (SN). You will find it on the type plate of the device.

All loggers, repeaters and GSM boxes also have an identification number (ID) which can be used by the Commander or the SebaDataView software to manage them. You will also find the ID on the type plate, or on a separate plate on the device. The identification number is identical to the last six digits of the serial number.

When inputting an ID, the preceding zero digits can be omitted. Thus, if the ID is “000815”, you need only enter “815”.

The loggers

3 The loggers

3.1 Function

The noise loggers are installed along a section of pipe directly on the pipe, or directly on fittings on the pipe.

Within the configured measuring window, they perform regular noise measurements, each 3 seconds in length. The volume level and frequency of each measurement are saved in the logger. While the noise level alone only records the general existence of a leak, together with the frequency it also provides information on the approximate distance in relation to other loggers.

The measurement results gathered by the logger can be queried later using a reading device (Commander/Reader/PC).

The quietest noise of the last measuring window is saved as an audio file. After reading out the data, you can actually listen to the assumed leak noise and immediately decide if it is a leak noise or background noise.

The “Real time measurement” function can be used to observe a logger “live” as it measures (see page 58).

With the “Direct recording” function can be used to listen to a noise in a pipe (see page

63).

Communication with the loggers is performed with short range radio only.

The loggers

3.2 Design

Introduction

Standard version

All noise loggers have a highly sensitive microphone with a large dynamic range, a data memory and a lithium battery inside. The standard loggers also have an internal radio antenna.

The loggers have the following external characteristics:

“Head” of the logger

“Foot” of the logger

TNC version

Element Description

Hole (M5 thread)

For fitting the supplied ring, which can be used for carrying the logger and pulling it out of the shaft.

Label with identification number (ID) Each logger has its own six-digit identification number.

Type plate The last six digits of the serial number (SN) on the type plate of the device are identical to the ID.

Marking Must always face upwards when the logger is fitted horizontally.

Magnetic foot Can be unscrewed and replaced by an adapter, or similar, from the assembly accessories.

The special TNC version of loggers have no internal antenna. Instead of the hole for the assembly ring they have an antenna socket for connecting an external antenna.

The loggers

3.3 Switching on and off

The noise loggers have an internal tilt switch and are switched on and off simply by turning them over.

Loggers standing on their foot are

switched on.

Each time a logger is switched on, its configuration data is reset to the default values. The time internally is also lost. Therefore, whenever the logger is switched back on, it must be reprogrammed (see page 50).

3.4 Memory

A logger’s internal memory allows a maximum of 100 pairs of values (the level and frequency of a measurement) to be recorded.

Furthermore, the quietest recording of the last measuring window is saved as an audio file (3 seconds in length).

Circular buffering is used, with the oldest stored measuring window being deleted after 100 measurements.

3.5 Power supply

Loggers standing on their head for longer

than 3 minutes are switched off.

Each logger has an internal lithium battery.

The actual battery lifetime depends on the intensity of use.

If a logger is always operated using the default configuration data, factory-set in the Commander, a battery lifetime of up to 5 years is possible.

Longer measuring periods and increased wireless activity/availability shorten the life of the logger battery. Severe fluctuations in climatic conditions also have a negative impact.

Flat batteries cannot be recharged. They must be replaced.

SebaKMT or an authorised service partner must change the batteries. Otherwise, water- and dirt-resistance of the logger cannot be guaranteed.

The Commander

4 The Commander

4.1 Function

The Sebalog Commander 3 is the mobile programming and reading device for noise loggers in the Sebalog N-3 series. The Commander is used to program the noise loggers before measuring. After measuring, the recorded data in the loggers can be queried with the Commander. Both current and older data can be displayed on the device’s screen and analysed in greater detail. Furthermore, a real time measurement can be performed (see page 58).

After connecting the supplied headphones, you can play back audio files of leak noises. It is also possible to listen to the current noise in a pipe (see page 63).
