Lora Wireless Magnetic Flap Level Meter
wireless magnetic flap level gauge is an innovative product that integrates an industrial wireless Internet of Things module (LoRaWAN/NB-IoT) on the basis of the traditional magnetic flap level gauge. It drives the dual-color flip column to display the liquid level through the magnetic coupling principle, and simultaneously wirelessly transmits real-time data to the cloud platform, achieving dual-redundant monitoring of mechanical indication and digital remote transmission. It perfectly resolves the risks of manual meter reading for high-risk storage tanks and the challenges of night inspections, providing a “what you see is what you get” intelligent liquid level safety solution for the process industry.
Description
Product advantages
1. Dual-channel trusted monitoring: On-site visual mechanical column flipping + 4-20mA/HART wireless remote transmission with dual backup, safety level increased by 200%
2. Zero power supply renovation: Battery-powered (with a lifespan of 5-8 years), directly install the existing magnetic flap, and the renovation shutdown time is less than 1 hour
3. Extreme working conditions adaptability: Pressure resistance 4.0MPa, temperature range -196 to 450°C, strong vibration/corrosion resistance (Hastelloy float is optional)
4. Intelligent alarm management: Dual wechat/sound and light alarms for high and low liquid levels, historical data traceability, and prediction of foam/false liquid level phenomena
5. Seamless integration: Compatible with Modbus RTU over LoRa, directly connected to DCS/SCADA, and supporting OPC UA data to the cloud
Core application fields
✅ high-risk chemical storage tanks: contactless monitoring of toxic/flammable media (benzene, liquid chlorine) (conforming to SIL2 safety grade)
✅ Energy and refining: explosion-proof liquid level monitoring for LNG storage tanks, high-temperature oil tanks, and reaction vessels
✅ Pharmaceuticals and food: Sanitary remote management of fermentation tanks and ingredient tanks in GMP clean workshops
✅ high-altitude/closed storage tanks: unmanned monitoring of large vertical tanks, spherical tanks, and underground sewage ponds
✅ multi-tank farm safety system: distributed storage tank liquid level centralized alarm, linked emergency shut-off valve
Put an end to the three major chronic problems in operation and maintenance: the risk of falling from manual climbing, difficulty in reading at night or in harsh environments, and lagging response to abnormal conditions
