Residential Ultrasonic Gas Meter Module
USM-G2.5M/G4M

Based on ultrasonic gas flow sensor technology, USM-G2.5M/G4M adopts patented L shape gas flow channel, the effective distance between two transducers are long, which facilitates the measurement accuracy, it's also anti-contamination that guarantees high stability . USM-G2.5M/G4M is used for assembling residential natural gas meters.

Features
  • Patented L-shape structure based on ultrasonic technology
  • Stable flow field distribution;
  • High sensitivity and accuracy with intelligent software algorithm for Air,100% CH4 and different natural gases
  • Anti-contamination that ensures long-term accuracy;
  • Low pressure loss due to absence of obstructing objects within flow path;
  • No moving parts, noiseless operation, no mechanical wear;
  • Low power consumption;
  • UART/TTL interface with direct output for connection;
  • Small size which permits compact designs;
  • Mass production capacity;
  • Compliant to OIML R137 and EN14236 class 1.5.
