General description The Meter Interface Unit (MIU) is an endpoint device for use in an Advanced Water Metering Infrastructure that enables utilities to optimize operations through data collection and analytics. The MIU device is an ultra-low power, two-way communication device for collecting water meters readings and designed to operate in LoRa network. The LoRa system is based on LoRaWAN for smart water meter management system. The MIU device connects either to the Mobile Data Collector or to the nearest gateway when it is in Fixed Mode network configuration. The device fits both Pit or Wall mounted Basement installation. The MIU is wired to the meter interface and collects the meter data every configured intervals (e.g. every 15 minutes, hourly, daily, etc.), stores readings records on a non-volatile memory and transmits hourly data several times a day. Key Features Two way network for sensor monitoring and remote control Built-in antenna Integrated non-rechargeable Lithium Battery 3.6V/19Ah Interfaces with meters Encoders or Pulser sensors Ultra low power consumption - Battery life time > 15 years (typical operation 4 daily reads) Data logging capacity: 30 days records at 15 minutes intervals End-to-end information security including authentication, integrity protection, replay attack and encrypted messages Comply with FCC part 15 non-license 3 ST Engineering Telematics Wireless Ltd 2. Installing the MIU The MIU is mounted either in a pit or in a basement. Pit mounted is depicted in the figure below. 3. Sensor Wire Interface The MIU has the following Interfaces:
Water meter reading interface. Valve control interface. The wired encoder is equipped with NICOR connector or bare wire. 4.

Regulation Information FCC Part 15 Regulation Class B digital device notice The digital circuit of this device has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
-Reorient or relocate the receiving antenna.
-Increase the separation between the equipment and receiver.
-Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
-Consult the dealer or an experienced radio/TV technician for help. 5 ST Engineering Telematics Wireless Ltd CAN ICES-3 (B)/NMB-3(B) This Class B digital apparatus complies with Canadian ICES-003. Cet appareil numerique de la classe B est conforme a la norme NMB-003 du Canada. FCC interference Notice This device complies with part 15 of the FCC rules. Operation is subject to the following two conditions:

To comply with FCC and IC RF exposure compliance requirements, the device should be located at a distance of at least 20 cm from all persons during normal operation. The antennas used for this product must not be co-located or operated in conjunction with any other antenna or transmitter. Le dispositif doit tre plac une distance d'au moins 20 cm partir de toutes les personnes au cours de son fonctionnement normal. Les antennes utilises pour ce produit ne doivent pas tre situs ou exploits conjointement avec une autre antenne ou transmetteur. The device meets the exemption from the routine evaluation limits in section 2.5 of RSS-102 and compliance with RSS-102 RF exposure, users can obtain Canadian information on RF exposure and compliance. WARNING! Changes or modifications to this equipment not expressly approved by the party responsible for compliance (ST Engineering Telematics Wireless Ltd.) could void the users authority to operate the equipment. 7
