IOTAFLOW FI-108 Series Remote Display Data Loggers provide local indication and long-term data storage for flow meters installed in industrial pipelines. Available in 1/2/3/4/8-channel configurations, the FI-108 accepts universal input signals and logs up to 180 days of data at one-minute intervals, making it suitable for utilities, oil lines, water networks, and process plants requiring dependable historical records.
Equipped with a 3-inch LCD display, onboard RTC (real-time clock), and USB 2.0 data export, the unit simplifies reporting for CGWA/CPCB submissions and operational audits. Powered by 220 VAC, it includes low and high relay outputs for alarm conditions.
Sized at 160 mm × 80 mm, the FI-108 Series is a compact, panel-mounted accessory that enhances visibility, provides accurate local monitoring, and strengthens digital compliance in Indian industrial flow-metering systems.
Telemetry Systems - 4G RTU IOT Gateways
IOTAFLOW Telemetry Systems combine 4G RTU Gateways and RTU-IOT4G NIC-compliant units to deliver fully automated, real-time data transfer for industrial water, oil, and groundwater monitoring applications. Built with integrated RTU, power supply, SIM tray, and 4G GSM/GPRS modem, these gateways support Modbus inputs from 1, 2, or 4 flow meters, allowing multiple meters to report through a single device. Powered by 220 VAC/ 24 VDC, each unit ensures continuous, interruption-free transmission of flow data to either the IOTAFLOW Cloud (iotaflow.in) or directly to NIC servers, depending on regulatory requirements.
Designed for India’s regulatory landscape, the system meets CGWA, CPCB, SPCB, and State Groundwater authority compliance by enabling automatic hourly data transfer, tamper-proof logging, and authenticated online reporting. Ideal for Woltmann, electromagnetic, ultrasonic, turbine, RPD, and industrial utility meters, these gateways eliminate manual data collection, ensure accurate flow monitoring, and support Industry 4.0-ready remote telemetry systems widely adopted across Indian industrial infrastructure.
