1、 Product Overview

DAQ-GP-FS4G 4G wireless pipeline wind speed and air volume Sensor is a high-precision monitoring device designed specifically for industrial IoT scenarios, integrating advanced technologyPitot static pressure tubeMeasurement technology and 4G/wifi/Ethernet full network wireless transmission module can Real-time collect wind speed and volume data of gas in the pipeline and remotely upload it to the cloud platform. The product adopts a solid-state structure design, with no movable parts, strong anti-interference, easy installation, long-term stability and other characteristics. It is suitable for gas flow rate and flow monitoring in various scenarios such as ventilation ducts, smoke exhaust ducts, industrial ventilation systems, etc. It can achieve remote data monitoring in remote areas or complex environments without wiring.

2、 Core functional features

1. 4G wireless high-speed transmission: Supports LTE-TDD/FDD full frequency band and 2G/3G network fallback, with a maximum downlink speed of 150Mbps and uplink speed of 50Mbps, using TCP/IPMQTTWaiting for multiple Protocol communications, automatic disconnection and reconnection, and heartbeat mechanism ensure stable and reliable data transmission.

2. High precision measurement performance: Based on the weighing principle and full range secondary calibration technology, the wind speed measurement resolution reaches 0.1m/s, the air volume calculation is accurate, and the long-term stability is ≤ 0.1m/s/year, meeting the needs of industrial level monitoring.

3. Multiple anti-interference design: Built in EMC anti-interference device, equipped with reverse protection and current limiting protection circuit, can resist electromagnetic interference in industrial environment, the positive and negative poles are reversed without damaging the equipment, and automatic current limiting protection is provided in case of abnormalities.

4. Multiple outputs and display options: Supports 4-20mA current output, 0-5V/0-10V voltage output, and RS485（Modbus-RTUProtocol）Wired output, optional OLED screen Real-time to display measurement data, parameters can be flexibly configured through software.

5. Convenient installation and maintenance: Adopting flange or bracket installation, equipped with high-quality silicone sealing rings, with small air leakage; Screw free terminal design, wiring can be completed without tools, and maintenance is simple in the later stage.

6. Data security protection: AES encryption andSSL/TLSProtocolProtect data transmission, ensure information integrity through CRC verification, support cloud remote configuration, FOTA and device status monitoring.
