Sentinel LNG Ultrasonic Custody Transfer Liquid Flow Meter

Sentinel LNG extends the use of ultrasonic technology into cryogenic applications.

Like other Sentinel ultrasonic custody transfer meters, it has no moving parts, to make it reliable, robust and cost effective. It uses BHGE's four-path Robust Path Configuration and Bundle Waveguide Technology to direct greater tranducer signals into the process while protecting the transducers from cryogenic temperatures.
