BRINGING ULTRASONIC FLOW MEASUREMENT TO THE EXTREMES
iSonic 8L-XT-Liquid Flow Measurement for Extreme Temperatures
XTC-Cryogenic Temperatures
XTH-Power Plant Feedwater Temperatures
The iSonic 8L-XT is our new addition to the iSonic family. The iSonic 8L-XTH and iSonic 4L-XTCare state-of-the-art multi-path flowmeters designed to measure fluids over a wide range of temperatures.
The iSonic 8L/4L-XT are ultrasonic flow meters of forged steel bodies with up to 16 high-precision non-wetted transducers, high-speed electronics, and lightning-fast signal processing resulting in the most innovative, accurate and reliable ultrasonic flow meter in the industry.
