NB-Fi modem BT-100 is designed to connect to the pulse outputs of utility meters and telemetry interfaces of sensors and gauges, enabling devices and sensors to get online and transmit data via NB-Fi network.

One NB-Fi modem BT-100 with pulse interface has two pairs of dry contacts, so customers can connect up to two water meters to this modem (for example, water meters for cold and hot water in one apartment).

NB-Fi modem BT-100 can be used for various IoT applications – Smart Grids and utilities, environmental monitoring, monitoring and alarm systems, Oil and Gas industry, Smart Agriculture.

Sensors and gauges that are used in manufacturing processes, in agriculture, for tracking of assets etc., as well as traditional utility meters with pulse outputs and RS-232/RS-485 interfaces can be connected to NB-Fi modems that will log the data from these devices and send it to WAVIoT IoT Platform.

While deploying AMI systems using WAVIoT utility meters, the existing water meters or building-level water and gas meters that do not have to be replaced can be connected to WAVIoT MDM system via universal NB-Fi modem BT-100.

NB-Fi modem BT-100 with pulse inputs transmit data every hour. This period may be customized - custom firmware for various IoT/IIoT projects is available on request.

WAVIoT NB-Fi modem BT-100 can be widely implemented in various IoT and IIoT solutions requiring energy-efficient and long-distance data transmission with autonomous operation, easy installation and fast ROI.

WAVIoT offer customized IIoT projects, develop special-purposed NB-Fi modems and adapt the existing IoT solutions to individual requirements.

WAVIoT IoT Platform

WAVIoT IoT Platform for the Internet of Things and the Industrial Internet of Things (IIoT) is a comprehensive solution to process all information from various IoT devices with NB-Fi transceiver that transmit data via the NB-Fi network.

WAVIoT IoT Platform can be used in Advanced Metering Infrastructure (AMI) and Smart Grid systems for power transmission and distribution, utility supply and management, energy services, agriculture, manufacturing, transport and logistics. WAVIoT IoT Platform collects, analyzes and stores data from millions of devices. The energy and utility sector will greatly benefit from the implementation of WAVIoT IoT Platform, as it reduces costs, increases convenience and improves security for the suppliers, customers and consumers.
WAVIoT IoT Platform is a cloud-based software that consists of the NB-Fi server (Head End System or HES) and the Meter Data Management System (MDM system or MDMS). WAVIoT IoT Platform collects and processes primary information from utility meters, sensors, gauges and other IoT devices, and provides tools for data analysis and visualization. Flexible API capabilities ensures integration with other IT systems, expanding the range of possible use cases.

WAVIoT IoT Platform can be installed in a corporate network and integrated with corporate AMI or enterprise system.
