SMD ultrasonic flow meter technology exhibits superior time resolution compared to its competitors — bettering the resolution of lower flow rates in medical, life science, laboratory and industrial applications. 0 Portable Transit Time Flow Meter Flow - Ultrasonic Flow Meters Non-Contacting Clamp-on Ultrasonic Transducers Works on Metal and Plastic Pipes Large Backlit Flow Rate Display and Totalizer Isolated 4-20mA Output Built-in 5-Key Calibrator 300,000 point data logger. Attached the picture and below the specs. Case Study. UNDERSTANDING DIAGNOSTIC AND EXPERT SYSTEMS IN ULTRASONIC FLOW METERS page 3 2 DIAGNOSTIC TOOLS OF AN ULTRASONIC FLOW METER 2. In this paper, the ultrasonic propagation in flare gas has been studied, the beam drift due to gas flow has been investigated and improvements from both mechanical and transducer perspectives have been made. The TDC-GP30 ultrasonic flow sensor chip from ams is one of the module's major components.
