Page 7: Overview And Preparation For Use
The PermaNet+ product family includes models with an interface for the HWM Hydrophone unit. They are (when the antenna and sensor are attached) of a waterproof construction, being designed to be permanently installed around a water network, listening for leaking pipes. -
Page 8: Cellular Communications And Sim-Card
APTOP COMPUTER The logger includes a serial communications interface. This enables the user to communicate with the logger during installation and make on-site tests. Communication requires the attachment of a HWM communications cable and also the HWM “IDT ” software. -

area have loggers that have produced sound recordings at precisely the same time, the approximate location of the suspect leak can often be found, using a process called Leak Localisation / Correlation. Note: Always use a ground microphone to confirm a leak location prior to commencing repair works. - Page 12 Deploy the loggers to sites without any checks being made (i.e., skip some of the • steps listed as optional). A follow-up team is then sent to selected sites to improve those that have communication problems. Installation consists of several steps… Installation sites must be selected.

Page 16: Displaying Logger Device Information / Logging Status
Note: Please refer to the IDT (PC version) user-guide. The above user-guide is written primarily for a multi-purpose data logger, however many of the IDT functions and settings are common to the PermaNet+ device. Where this is so, they will only be mentioned briefly in this guide. The PermaNet+ operation is not that of a general-purpose data logger but has its own specialised leak determination programs. -
Page 17: Configuring The Permanet+ Logger
ONFIGURING THE ERMA LOGGER 4.1 S ETUP OF REGULAR REPETITIVE ERMA PROGRAM To configure the logger, first select the Setup tab in IDT. The IDT display is adaptive in behaviour and shows information and controls which change depending on previous selections / de-selections. - Page 18 There are 2 panels that determine the primary method the logger uses to send data when it calls into the server. They include a setting for the call-in time and also which days of the week to call in. Any unsent data will be sent at next call-in time.
- Page 19 One section of the Logging Parameters panel is a “Leak Threshold” selection. This determines which threshold is being used as the judgement of a leak / no-leak condition during leak determination. (i.e., it is a sensitivity control). The “send leak sound recording when leak first detected”...

4.2 A DDITIONAL DATA FROM A TIME PROGRAM QUALOGS The “enable aqualogs” control will (when set) cause the PermaNet+ unit to produce Aqualog data. Aqualog production is a temporary addition to the logger’s regular task of leak determination. Enabling Aqualogs causes IDT to show another panel for the Aqualog settings An Aqualog produces data for a histogram of the noise levels that appear on the water network. -

NSTALLATION 5.1 I NSTALL LOGGER Diagrams of typical installations of PermaNet+ with Hydrophone are shown (opposite and below). The PermaNet+ unit must be mounted in a suitable location where the Hydrophone attached can reach its intended installation point. Position the equipment and antenna away from sources of electrical interference such and motors or pumps. -

Then close the fitting again and inspect for cleanliness whilst following any applicable water hygiene guidelines. Silicon grease If using the London Round Thread adaptor, first lightly coat the internal rubber seal with... - Page 24 Fit the London round thread adaptor to the Hydrophone sensor taking care not to damage or cross the threads. (see Tighten the adaptor until the castellations fitted to the top of the adaptor are secured by the quick release interlocking mechanism fitted to the Hydrophone sensor.
- Page 25 Note: Should the hydrant location be flooded, ensure that the lead is connected prior to immersion . The sensor connector is only water proof after connection. Open Hydrant valve fully to allow water into the hydrophone. A fully open hydrant valve will give the best noise transmission to the Hydrophone.

5.4 I NSTALLING THE ANTENNA AND TESTING CELLULAR COMMUNICATIONS Only use HWM-provided antenna for use with your logger, to ensure the radio interface meets approvals requirements (safety, etc). The PermaNet+ unit has a metal “FME” style connector for connection of an antenna. -
Page 27: Antenna Options And Installation Guidelines
NTENNA PTIONS This section describes a variety of the antenna alternatives that can be supplied for use with the PermaNet+ logger. Only use HWM-provided antenna for the logger, to ensure the radio interface meets approvals requirements (i.e., safety). 6.1.1 Monopole For most installations a monopole antenna will give acceptable performance. -

Page 35: Viewing Your Data
Site data is best viewed with the viewing tool (usually a website). An example viewing tool for use with PermaNet+ devices is the HWM PermaNETWeb website. PermaNETWeb can display the status of multiple devices (sites) simultaneously, thus allowing the state of an area of a utility network to be easily visualised. -
Page 36: Interpretation Of Leak Data
NTERPRETATION OF 8.1 L EVEL AND PREAD RESULTS The raw sound level is measured on a scale between 0dB and 99dB. The signal Level (in decibels) is the point on the dB scale where there is a clearly identifiable peak. The Spread is the width (number of dB values) that can be considered to be included within the over-all shape of the biggest peak. - Page 37 Level = 48 Spread = 06 11111111 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 Each test will provide different results depending on the ambient noise conditions at any given deployment. A leak will be indicated by a consistent noise generated at a higher intensity than any random background noise, so the best indication of a leak is a high peak with a very narrow spread, see example on the right below.

8.2 A QUALOG ISTOGRAM RESULTS XAMPLES The following section discusses how to read Histograms. Note: A standard histogram is amongst the data received from the logger once per day. An ‘Aqualog’ is the same as a ‘Histogram’ but is manually triggered and has customisable timings. - Page 39 In the below set of examples the strongest leak indication is No 3 – a narrow spread (5dB) and a strong level (60dB). The others do not offer good indications of leaks: No 1 … Big spread / poorly defined peak, No 2 …...

Contact your HWM representative for more details if required. A battery swap must be accompanied by a reset of power-use counters for the logger to perform normally. Batteries can be returned to HWM for disposal. To arrange the return, complete the • on-line RMA form: https://www.hwmglobal.com/hwm-rma/... - Page 42 All images, text and designs are protected by international and UK copywrite law and remain the property of HWM-Water.
