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 2 to be connected easily to a wide range of sensors and meters, including the SonicSens ultrasonic level sensor, SDI12, RS232 and Modbus
Remote 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 2’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 2 is monitoring rising water levels (SonicSens) or when investigating network events.
Innovative Fast Logging
The LX 2’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.
