It is battery operated, watertight OP 681 and easy to install. When combined with the - also battery driven - WATERFLUX 3070, it forms a perfect solution for monitoring water distribution networks. Applications: • remote meter reading • leakage detection • district metering • warning messages in case of calamities Competitively priced, the KGA 42 ensures a rapid return on investment by contributing efficiently to improving network yield. 10/2011 -4001696801 -TD KGA 42 R01 en www.krohne.com 3 p PRODUCT FEATURES Highlights Datalogging • capacity in GSM mode 2000 records; in GPRS mode 6000 records • no data loss in case of power failure (empty battery) GSM/GPRS communication • built-in GSM /GPRS modem for data transmission • SMS alarm messages • built-in high performance antenna designed for the installation in manholes (low reception Levels, disturbances caused by the concrete structure and manhole cover, etc.) Visual LED-based diagnostics • LED-based operator dialog • start-up and maintance assistance (power on/off, connection to GSM network, reception Level, etc.) Bluetooth communication • wireless connection with PC or pocket PC • ability to work outside a manhole • configuration read/write • full diagnostics and data viewing Water tightness • sealing concept that guarantees water tightness (IP 68) • military grade connections Autonomous power supply • long-life lithium battery • very low power consumption guarantees an autonomy of years • sensor power feeding (suitable for passive output) • permanent power consumption metering 4 www.krohne.com 10/2011 -4001696801 -TD KGA 42 R01 en PRODUCT FEATURES 0 1 .2 Features Meterings and flows When connected to flowmeters positioned at strategic points in a water network, the KGA 42 provides information concerning the behaviour of each monitored zone. Metering index recording and flow rate are calculated at a user-defined frequency. Measurements In addition to metering and flow monitoring, network sectoring may require pressure monitoring. The KGA 42 offers 2 analog inputs (AI) to connect 4-20 mA sensors that are directly powered by the KGA 42. Measurements are acquired and saved at a user-defined frequency. Calculations and archiving Average flow rates, daily volumes and night time flow rates (MNF) are automatically calculated by the KGA 42. The values are archived according to data types: • meterings (indices and average flow rates) • analog inputs (pressure measurements, etc.) • daily reports (night time flow rates (MNF), indices, volumes, min. /max. flow rates) Archives and reports are sent to internet each day. Through a dedicated web site (WEB KGA) the data can be viewed or exported for further analysis. Signalling and warnings Inputs (DI) can be assigned to switches to notify specific events (manhole cover open, flow meter fault, etc.). A change in signalling status can trigger the transmission of status or warning SMS messages to a mobile phone. A timer can be configured to filter out undesirable status changes. Ease of operation Each KGA 42 is supplied with a CD-ROM, containing Softools software. Softools is a configuration and diagnostic tool. It combines ease of use and an intuitive graphical environment: • Configuration: the configuration wizard guides users through the steps involved configuring a KGA 42. The successive screens are used to rapidly and easily set the main operating parameters. Configuration read and write operations are performed over a bluetooth link. • Diagnostics: Softools facilitates KGA 42 installation and can be used for various operating tests: input (DI and AI)tests, best GSM/GPRS operator test, reception level test to determine optimal location of the KGA 42, etc. • Viewing: during manual activation, the metering, measurements and flow rates can be viewed. It is also possible to accurately determine the power consumed by the KGA 42, along with the battery's remaining lifetime. LED diagnostics Different coloured LED's on the KGA 42 provide diagnostic information (power on/off, SIM card present, network connection, reception level) 10/2011 -4001696801 -TD KGA 42 R01 en www.krohne.com 5 TECHNICAL DATA 2.1 Technical data • The following list is just an excerpt of the most important technical data.
