The Sentinel LNG is an ultrasonic custody transfer flow meter for liquefied natural gas and cryogenic liquids, featuring a fully welded, full-bore design with no moving parts and transducers protected by a bundle waveguide that isolates them from cryogenic temperatures. It uses active temperature compensation and pulse echo to measure dead time in real time for high accuracy. Electronics support HART and Modbus RTU, with options for remote mounting up to 91 m (300 ft). Flowspools are available in sizes from 4" to 36", with ASME B16.5 or B16.47 flanges, 150 or 300 lb pressure ratings, and ASTM A182 304/304L or 316/316L stainless steel construction. Certification includes ASME B31.3, PED, and explosion-proof ratings for Class 1, Div 1 (Groups B, C, D) and II 2G Ex d / Ex de IIC.
The Sentinel LNG ultrasonic custody transfer liquid flow meter extends cryogenic applications to -200 C. Like other Sentinel meters it is reliable, robust and cost effective. With no moving parts, a robust path configuration and bundled waveguide technology, the signals can enter the process while protecting the transducers from cryogenic temperatures.
