Models AQ3 loT Meter Logger Cat-M/NB-IoT AquaLink Water network efficiency The AquaLink Meter Logger, designed specifically for water meter reading, utilizes NB-IoT communication for efficient data transmission. Equipped with multiple input ports (cables), it can accommodate up to 4 digital inputs, providing flexibility for various monitoring requirements. Additionally, it offers the option to connect an AQ pressure and temperature sensor, enhancing its functionality. With an IP68 waterproof rating, the logger is resistant to water ingress, ensuring reliable operation in diverse environmental conditions. The external SMA connector allows for antenna replacement, while the option to replace batteries ensures extended device lifespan. Furthermore, the built-in humidity and temperature sensor continuously monitors environmental conditions, ensuring that the device remains properly sealed and moisture-free. Featuring a modular design, the logger's upper part can be easily replaced in case of electronic failure, while all cable connections remain intact in the well. Bluetooth connectivity enables seamless communication, with configuration options available through an Android app. • 4x Digital programmable inputs • Dedicated AQ Flow and Pressure input • Switch alarm input • Internal humidity and temperature sensor for detection of water intrusion inside housing Input types (each configurable in software): • Digital (measures pulses from HRI, REED, Cyble, short circuit...) - counter mode • Built- in Cat-M/Cat-NB/GPRS/EDGE modem (optional other) • LTE RF Power Class (Class 5 (Typ. 21dbm)) • 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) Weight: 700g (without cables) Mounting: • 3 holes in the housing for zip ties or wall mounts Operating environment: Temperature range: Reduced battery life outside -20°C and +60°C Power supply: • Up to 3x 3,6V Li-SOCI2 internal batteries • Standard battery life up to 10 years (depending on configuration) • Batteries easily replaceable • Optional mains / solar power supply / rechargable batteries Uploading data: • Standard to AquaLink Cloud • Optionally via ODBC API to SCADA module • Optionally HTTP open protocol Firmware features Configuration: • 2 way communication with AquaWeb server • Automatic Firmware update over internet or USB cable • All parameters can be configured remotely via internet EN AQIII 2 AQ Link GmbH reserves all the rights to changes product specifications at any time without notice.
