MAWS100 is a compact system for hydro-meteorological monitoring when a small number of sensors and limited number of telemetry options are required. It is especially designed for unmanned operations at remote sites requiring high reliability and low power consumption. MAWS100 uses a field-proven and highly accurate Vaisala data logger technology with advanced software. MAWS100 is well suited for the Vaisala Weather Transmitter WXT520, and for cellular telemetry.
The system architecture is designed to support a broad range of analog and serial sensors. Sensor measurements, statistical calculations, data logging on a compact flash card and versatile data transmissions are performed according to a user-configured setup made with the user-friendly Vaisala Setup Software Lizard. Vaisala Realtime Display Software YourVIEW is included for viewing real-time data as required.
Field-proven reliability of MAWS100 enclosures feature IP66 (NEMA4X) protection. In MAWS100 all sensors and telemetry devices are connected to the system using high quality polyurethane cables with IP68 connectors allowing quick and trouble-free installation.
MAWS100 has a low power consumption, e.g., the average power consumption is only 10 mA when measuring with five basic sensors. In many cases a solar panel with a backup battery of 5 Ah is enough for powering a MAWS100 system. A mains (AC) power supply is optional to power extended systems with frequently sending (powered) telemetry devices.
The system provides interfaces with almost any type of telemetry, terminal, displays as well as smart sensors. With optional plug-in modules the number of serial ports can be enhanced from 2 up to 8 ports, enabling multiple RS-232, RS-485 and SDI-12 connections. MAWS100 can be connected directly to a LAN network using Ethernet Communication Module DSE101 offering a 10/100Base-T Ethernet. Other options for telemetry include GSM/GPRS, PSTN, and serial connections.
MAWS100 is expandable with Digital I/O Unit QMI118 which adds 8 digital outputs and 8 digital inputs for sensor interfacing, power optimizing, and unmanned control functions based on user-defined requirements.
MAWS100 can be equipped with innovative installation aids that significantly lower installation and maintenance costs. A single maintenance person can easily and safely tilt the Vaisala Tiltable Masts.
