Introduction
Based on ultrasonic gas flow sensor technology, USM-MN/MP-G1.6/G2.5/G4 & USM-MN/MP-L-G1.6/G2.5/G4 adopts patented V 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-MN/MP-G1.6/G2.5/G4 & USM-MN/MP-L-G1.6/G2.5/G4 is used for assembling residential natural gas meters.
Features
1. Stable flow field distribution
2. High sensitivity and accuracy with intelligent software algorithm for air, different natural gases, natural gas+up to 23%H2, and LPG
3. Low pressure loss due to absence of obstructing objects within flow path
4. Low power consumption
5. Comes with integrated temperature compensation as standard, with optional pressure compensation available
6. UART/TTL interface with direct output for connection
7. Small footprint which permit compact designs
8. Compliant to OIML R137 and EN14236 class 1.5
