Water Pressure & Flow Data Logger
Integral PSTN or SMS/GSM/GPRS Telemetry Options
MultiLog is a highly advanced and versatile multi-channel data logger which can be supplied with up to four inputs for monitoring any combination of digital or analogue signals. Its sophisticated electronics, robust construction and long battery life have been proven to deliver consistent and reliable data in some of the harshest environments on earth.
Innovative "Secondary Channel" Feature
MultiLog is ideal for monitoring flow and/or pressure in a district or zone to assess demand, leakage and conformance. It can perform dynamic flow and pressure analysis of network models, and has an innovative ‘secondary channel’ feature which enables additional fast logging down to one second intervals. This is invaluable when more detailed investigation is required, such as pressure spikes and ‘true’ minimum night flow
Previously, secondary channel logging could only be used as a manual direct download but lower GPRS data transfer rates have enabled HWM to make this a telemetry feature. The standard logging continues alongside the secondary channel logging for general reporting purpose
The Touch Pro from HWM represents a breakthrough in leak detection technology. It features improvements throughout the leak noise processing path to provide improved performance; especially in the most difficult leak detection situations. This enables it to give the best performance in traditionally difficult conditions, such as on plastic and large diameter pipes.EASY TO USE
Touch Pro features a high visibility full colour VGA touch screen to greatly improve data entry and the quality of graphical presentation. The intuitive user interface enables the unit to be operated with minimal key presses and the helpful step by step menu system easily guides the user through the correlation process.HIGH QUALITY PERFORMANCE
The large screen clearly displays correlation results and supportive information, and the innovative high contrast mode enables good visibility even in bright sunshine.
The unique Automated Filtering Intelligence System (AFIS) automatically runs up to 55 different filter combinations on each correlation, checking the quality of the result and optimizing the filters until the best result is obtained. AFIS works with both live and pre-recorded correlation data and makes manual filter setting a thing of the past by effectively building an “expert user” into the unit.
The outstation is compact with an upgraded high quality, long range radio transmission. It also features a magnet to secure onto metallic surfaces.ROBUST FOR LONG-TERM USE
The specially designed robust case not only carries and protects all components, it also allows the base station and outstations to be charged from a single power lead and displays charging status. Units can be stowed with sensors still connected for faster deployment in the field.
Using our extensive experience of correlator design and manufacture, HWM has created an easy to use system that delivers the best all round performance at a highly competitive price.KEY FEATURES
MultiLog LX-2 upgrades the highly versatile battery powered telemetry data logger with remote SMS/GPRS telemetry. Benefiting from the new ‘unilog’ platform and processing capability the LX-2 adds many new features to its market leading predecessor The proven design accommodates very shallow installations like Atplas. The logger is ideal for many applications, including monitoring flow and/or pressure in a district or zone to assess demand, leakage and pressure conformance; logging key customers. The logger utilises the latest advances in GPRS technology to provide rapid transmission at low cost, enabling data to be retrieved more frequently for analysis and response.MULTIPLE INPUT OPTIONS
In addition to digital (flow) and analogue (pressure, 4-20ma, leak noise) inputs, convenient serial input option enables the LX to be connected easily to a wide range of sensors and meters, including the SonicSens ultrasonic level sensor, SDI12, RS232 and ModbusREMOTE DATA VIEWING
Data can be transmitted to HWM’s secure DataGate web based portal from which it can be viewed on any internet enabled device via the HWM Online website. Alternatively, the logger can send data directly to a customer specific server. Data can also be downloaded locally via a convenient Infra-Red interface.REMOTE PROGRAMMING / FIRMWARE UPGRADES
This environmentally friendly option helps reduce the LX’s carbon footprint and TOTEX by removing the need for expensive and time consuming site visits. It also ensures that the logger can always be updated quickly and efficiently.ACCELERATED DIAL IN ON ALARM
When an alarm is triggered, the logger can be programmed to automatically accelerate its scheduled transmission time to improve visibility and assist investigation. This is particularly useful when the LX is monitoring rising water levels (SonicSens) or when investigating network events.INNOVATIVE FAST LOGGING
The LX’s innovative secondary channel feature enables additional fast logging up to 25Hz. This is invaluable when more detailed investigation is required, such as transient pressure spikes and ‘true’ minimum night flow. Previously, fast logging could only be used as a manual direct download but faster GPRS data transfer rates and reduced costs have enabled HWM to make this a telemetry feature. The standard logging continues alongside the fast channel logging for general reporting purposes. Fast logging can be triggered from a time window or alarm threshold.EXTENSIVE BATTERY LIFE
Replaceable internal batteries can power the logger for over five years when data is transmitted every 12 hours. A range of low cost external battery packs are available which maintains the five year battery life when sending data every hour, 30 minutes or 15 minutes.
Tmic is a highly cost effective mini water leak detection unit with visual and audible indication of the leak. The unit fits conveniently into a pocket, making it perfect for any water specialist or plumber for instant, on the spot leak monitoring.
Lightweight and portable, Tmic assists technicians to hear sounds on the water network which would otherwise be inaudible to the human ear. The unit is operated with a simple push button and displays a visual indication of noise levels together with excellent sound reproduction through high quality Bluetooth headphones.
The sensor tip can be connected to a meter long rod or placed directly on the pipe or fittings. Sensitivity levels are far beyond what is possible with mechanical listening sticks.
Tmic’s memory will store a noise level and show it on its LED display. By visually comparing the current and previous noise level the operator can quickly identify where the noise is loudest. The LED also displays the battery level and Bluetooth pairing status. An LED torch is incorporated into the unit for use at night or to investigate dark chambers.
The unit and its accessories are supplied in a case with precision cut foam compartments to protect in transit.Key Features
The PermaNet system from HWM combines Permalog leak noise sensor and our versatile telemetry data
technology to create a fixed network to monitor leakage.
Once installed, leak data calculated using the proven Permalog algorithm, and secondary data, is transmitted via low cost GPRS or SMS telemetry. This removes the requirement for expensive site visits and “drive by” data retrieval.POTENTIAL LEAK AREAS QUICKLY IDENTIFIED
PermaNet+ allows leakage teams to monitor the status of each logger deployed from map based host software any internet enabled device using ALMOS LEAK. The system works in conjunction with Google Maps technology to provide a live on screen tracking, allowing leakage teams to respond quickly to problem areas and bring them under control efficientlySECONDARY VALIDATION
Once the presence of a leak has been identified, secondary measures can be used to check and remove
‘false positives’ and also to localise the leak position.
Correlation – Audio files are used to correlate remotely to localise the leak position for follow up
Aqualog – remotely retrieving the Aqualog detailed noise graphic, clearly indicates the consistent presence of a leak.
Audio – For operators who prefer to ‘hear’ their leaks audio files are transferred to the host.
