GSM/GPRS Data Loggers LS/LT Range- Brochure

The SOFREL LS and LT data loggers communicate via GSM or GPRS links. They have been specifically designed to remotely monitor water networks including but not limited to metering manholes, storm overflows and sewers etc. Completely watertight (IP 68), battery-powered with an autonomy of up to 10 years, they include a GSM/GPRS modem and high-performance antenna.Innovative, robust, simple to fit, SOFREL LS and LT provide an effective and economical answer to:? monitoring of water District Metering Areas (DMA),? leak detection,? detection of overflows into storm overflow sewers,? remote meter reading,? control of remote sites, etc.SOFREL LS/LT RANGEG S M / G P R S d a t a l o g g e r sinnovation and erformanceBluetooth communication- Wireless connection with PC- Ability to communicate outside of the manhole- Configuration read / write- Full diagnostics - Data transmissionGSM/GPRS Communication- Built-in GSM/GPRS modem- SMS or GPRS mode communication- Built-in high-performance antenna adapted to the constraints of manhole installation (low signal reception level, disturbances caused by the concrete structure and cover, etc.).Visual LED-based diagnostics- LED-based operator dialog- Implementation and maintenance assistance (start-up/shutdown, GSM network connection, reception level, etc.)Watertightness- Closing concept guaranteeing reinforced watertightness (IP68)- «Military» grade connectionsUser opening- Inserting a SIM card- Replacing the battery- Lock ring and tool guarantee watertightness.Battery powered- Long-life lithium battery- Very low-power consumption guarantees an autonomy up to 10 years- Sensor power feeding- Permanent consumption metering and monitoringS O F R E L L S / L T : GSM/GPRS data loggers for water network monitoringMain a licationsMonitoring of water DMAsSOFREL LS was specifically designed for monitoring water District Metered Areas and leak detection. Connected to flow meters or district metering meters, it records pulses, calculates average flow, daily volumes and night flows for monitored zone. It regularly checks the pressure in the pipes and generates an alert in the event of threshold overrun. It provides an additional solution for reducing Non Revenue Water.Storm overflow sewer monitoringSOFREL LT possesses archiving functions able to meet the self-monitoring and diagnostic requirements of waste and rain water networks. Connected to a sensor, SOFREL LT records switches to overflow and determines the number and duration of these overflows. It can also power an ultrasonic sensor (4-20 mA) to monitor water levels in the drain.Control of remote sitesThanks to their wireless GSM/GPRS communication and battery-powered operation, the LS and LT data loggers allow the remote surveillance and monitoring of the most isolated facilities. They regularly record data (levels, pressures, etc.) and send SMS alerts in the event of status change or threshold overrun (overflow, excess pressure, etc.). They represent the ideal solution for monitoring reservoirs without electrical power supply, remote industrial facilities, water tables, rivers, irrigation canals, etc.Remote meter readingThe SOFREL LS and LT can be used for remote water or energy consumption readings in buildings or for major consumers (industrial plants, hospitals, hotels, etc.). The metering data is stored at user-definable periods in order to allow close monitoring of consumption and to generate periodical reports that are then regularly transmitted to the SCADA central station. The system rapidly detects any drifts and guides the maintenance teams in their interventions.www.ls-leak-detection.comFor more information:S O F R E L L S / L T : GSM/GPRS data loggers for water network monitoring? Fitting the SIM card:Though completely watertight (reinforced IP68 protection), the LS and LT data loggers can easily be opened on-site by the user to access the SIM card or battery. The lock ring and locking system ensure that the products remain completely watertight.? Configuration: Graphical and user-friendly, the SOFTOOLS configuration software guides the user step by step through the creation of a new LS or LT. The main operating parameters can be accessed and modified from a central view. To facilitate on-site work, the connection between the configuration PC and the data logger is established via a Bluetooth link enabling the operator work safety and easily outside the manhole.? Diagnostics: Equipped with color LEDs, the SOFREL data loggers offer a first level of visual diagnostic (active status, network connection, GSM reception level, etc.). More in-depth operating tests (input checks, best GSM operator test, signal reception test, remaining battery power, etc.) can be conducted via the Bluetooth link using a PC. Operators can also run a product test or check the statuses from their mobile phone, via a simple SMS message.Easy to fit and useS O F R E L L S / L T : GSM/GPRS data loggers for water network monitoring? Communication with centralized systems:On a regular basis, LS and LT transmit their recorded data (meter readings, status changes, DI and AI inputs, reports, calculations, etc.) to the SCADA central stations or supervisory control software systems. A SOFREL OPC communication server is also available.Data processing? Communication with mobile phone: SOFREL LS or LT data loggers can send their data to a mobile phone by SMS message. Digital Inputs (DI) can be assigned to contacts to notify alarms, intrusions, faults, etc. A status change or threshold overrun can trigger the transmission of an alert SMS message to a mobile phone.?

This solution does not require the purchase of a software license and avoids the constraints associated with managing a SCADA central station. The view screens and curves are fully customizable. The data, that can be transferred to Excel, are perfectly secure and completely confidential.Main features SOFREL LS SOFREL LTPresentation LS10 LS42 LS42EA LT42 LT42EAIP68 watertightness (certi?ed for immersion under 1 m of water for 100 days) ? ? ? ? ?LED-based operator dialog ? ? ? ? ?Connection cable with "military" grade connectors (2 m) ? ? ? ? ?Dimensions: H261 x W155 x D176 mmPower supplyUser-changeable lithium battery ? ? ? ? ?Standard battery life (depending on conditions of use): 5 years 5 years 5 years 5 years 5 yearsHigh-capacity battery life (depending on conditions of use): 10 years 10 years 10 years 10 years 10 yearsCommunicationBuilt-in dual band antenna ? ? ?Watertight external dual-band antenna with cable (4m) ? ?Built-in GSM/GPRS modem ? ? ? ? ?Communication with 2 different PCs ? ? ? ? ?Transmission of alert SMS messages to a mobile phone ? ? ? ? ?On-site connection to logger via Bluetooth ? ? ? ? ?Data acquisitionDigital Inputs (DI) 1 4 4 4 4DI can be assigned to "in/out" meters ? ?Number of alert DI to mobile phone 1 4 4 4 4Optional Analog Inputs (4-20 mA AI remotely powered by the LS/LT) 0 2 2 2 2Threshold overrun alarms 4 4 4 4 4Con?gurable DI positioning logic (NO/NC) ? ?Data archivingOn DI and threshold status change ? ?Variable archiving period on detection of DI status change ? ?Daily report of the number of status changes (DI or threshold) ? ?Daily active status time report (DI or threshold) ? ?The SOFREL LS/LT data loggers are based on an in-depth knowledge of water networks and on more than 35 years of experience. These innovative industrial products perfectly meet the specific features required for drinking water district metering, waste and rain water network management and the constraints of remote sites.Based on common electronic and mechanical components, the products in the range are distinguished by their software, by the number of inputs and by their options.Te c h n i c a l f e a t u re s o f t h e L S / L T ra n eBluetooth communication- Wireless connection with PC- Ability to communicate outside of the manhole- Configuration read / write- Full diagnostics - Data transmissionWatertightness- Closing concept guaranteeing reinforced watertightness (IP68)- «Military» grade connectionsDC30-SOFREL LS/LT range-En-2011-06 - Note: non-contractual document.
