Product Details

Description:

Based on ultrasonic gas flow sensor technology, USM-MN/MP-L-G1.6 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-L-G1.6 is used for assembling residential natural gas meters.

Features:

Stable flow field distribution
High sensitivity and accuracy with intelligent software algorithm for air, different natural gases, natural gas+up to 23%H2, and LPG
Low pressure loss due to absence of obstructing objects within flow path
Low power consumption
Comes with integrated temperature compensation as standard, with optional pressure compensation available
UART/TTL interface with direct output for connection
Small footprint which permit compact designs
Compliant to OIML R137 and EN14236 class 1.5
