YW-TW LoRaWAN IoT Gas Meter with 1.6-4 m³/h Flow Range, 3000m Wireless Range & Explosion-Proof Certification
The YW-TW Intelligent Gas Meter is a next-generation centralized reading terminal designed for flow measurement of natural gas, liquefied petroleum gas, artificial gas, and other gases. This IoT-enabled device integrates gas metering, remote reading, and monitoring capabilities with high reliability, accuracy, and low power consumption.
Utilizing LoRaWAN/CAT.1 wireless transmission technology, this meter automatically uploads consumption data to application platforms for remote monitoring. It addresses traditional gas meter challenges including difficult home meter reading, payment processing issues, and supply-demand inaccuracies. Certified with ExibIIBT3 Gb explosion-proof rating, it's suitable for Zone 1 and Zone 2 environments containing IIA-IIB and T1-T3 explosive gas mixtures.
LoRaWAN wireless technology enhances anti-interference capabilities and improves data reception accuracy with barrier-free transmission distances exceeding 3000m.
System-based prepayment with remote valve control via platform commands for efficient management.
Daily timing and key wake-up data transmission reduces battery consumption while maintaining rapid response times.
Automatic LCD fault display, audible alarms, and valve closure during low voltage or abnormal conditions.
Platform access for monitoring gas consumption, battery status, and remote valve control operations.
Pulse signal open circuit self-inspection ensures precise gas measurement and data reliability.
