SITRANS FUG1010 clamp-on non-intrusive ultrasonic flowmeter is ideal for numerous natural and process gas applications. It uses  an internal AGA-8 table for fixed gas composition to compute standard volume and is in compliance with AGA-10 speed of sound measurement practices.

The meter is available in single, dual and optional four channel/path configurations. There are two enclosures to choose from: wall mount and wall mount explosionproof.

Application examples include check metering, flow survey verification, lost and unaccounted for (LAUF) gas analysis, and production and  storage.  

Pair the SITRANS FUG1010 interface detector with the SITRANS F US Thickness Gauge to ensure precise flow measurement.
