Rosemount™ TGU 53 Tank Radar Gauge for LNG
Your profitability and reputation as an LNG operator demands buyer-seller agreement accuracy.
The Rosemount TGU 53 Tank Radar Gauge is built for the task. The radar transmission is guided through a full length still pipe measuring the surface of the product and the patented array attenuator ensures accurate readings from the very bottom of the tank. Using the accurate and reliable TGU 53 you can perform your cargo transfer with complete trust. With dual channel technology primary and secondary level measurements are enabled by two independent radars, yet in one housing and a single still pipe installation. Single tank penetration makes for affordable new and retrofit installation.
