Water network efficiency AquaLink technical specification Models AQ3 RTU loT Data Logger GSM / NB-IoT The AquaLink Data Logger with GSM communication offers advanced functionality for monitoring water distribution systems. It features muLtipLe input ports (cabLes) that aLLow connection to 4D/5A inputs, providing versatility for various measurement needs. Additionally, it can be optionally equipped with 2 reLay outputs, which can controL vaLves, pumps, and other devices. The IP65 device is suitabLe for use indoors, such as in water towers or water reservoirs, and must be connected to an eLectricaL power suppLy. The externaL SMA connector enabLes easy antenna replacement, whiLe the option to repLace batteries ensures extended device Lifespan. Designed for ease of maintenance, the device's moduLar design aLLows for the replacement of onLy the upper part of the Logger in case of electronic faiLure, whiLe aLL cabLe connections remain intact in the space. The data is logged and sent to the AQWeb server where it is displayed graphically and allows for more analysis types. • 5x programmable inputs (4x Digital/Analog/4-20mA + 1x Analog/4-20mA) with programmable power output for each input • Dedicated AQPressure input • Switch alarm input • Internal humidity and temperature sensor for detection of water intrusion inside housing Outputs: Optional • 2x solenoid/relay pulse output with programmable voltage output 3,3V-20V, reverse polarity support and up to 20W pulse • Digital (measures pulses from HRI, REED, Cyble, short circuit...) - counter mode • Analog (measures voltage 0-3V) • 0/4-20mA current loop (2,3 and 4 wire type support) Each input can generate a separate power output on a dedicated pin to power the connected sensor power every time a measurement is taken. The voltage generated for each input and the duration of power is configurable for each input, with selectable voltages from 3,3V to 20V and configurable current limits up to 4A in 50mA steps. • Built- in GSM modem (GSM/GPRS/EDGE/UMTS/HSDPA/HSPA+/LTE-TDD/LTE-FDD) or Cat-M/Cat-NB/GPRS/EDGEBuilt- in GSM modem (GSM/GPRS/EDGE/UMTS/HSDPA/HSPA+/LTE-TDD/LTE-FDD) or Cat-M/Cat-NB/GPRS/EDGE • GPRS and SMS communication (configurable) to a AquaWeb server • Accepts normal size SIM cards • Integrated Bluetooth for on site programming (v4.2BR/EDR) • Local connection trough USB cable (for initial configuration and troubleshooting) Mechanical: Housing: Mounting: • 3 holes in the housing for zip ties or wall mounts Operating environment: Temperature range: Reduced battery life outside -20°C and +65°C Power supply: • Extrnal power supply mains 230 VAC with standar EU connector, Output 12V / 5A • Standard battery life up to 6 years (depending on configuration) • Optional mains / solar power supply / rechargable batteries EN AQIII 2 AQ Link GmbH reserves all the rights to changes product specifications at any time without notice.
