Oval Gear Flow Meter

LC-Series

The TUFM1100-EC Wall Mount Ultrasonic Flow Meter is a transit-time ultrasonic flow measurement system designed for continuous monitoring of liquid flow in pipelines. The meter uses clamp-on ultrasonic transducers mounted externally on the pipe, enabling accurate flow measurement without pipe cutting or process interruption. With wide pipe diameter compatibility, advanced communication options, and optional thermal energy measurement capability, the TUFM1100-EC is ideal for industrial flow monitoring, energy audits, and system performance analysis.

  • Highly accurate flow measurement for industrial liquids
