Dynasonics, of Racine, Wis., presents its Series TFXL Ultrasonic Transit Time Clamp-on flow meter that uses time-of-flight ultrasonic technology to measure almost any liquid containing less than 40 percent TDS or aeration. The non-invasive unit provides easy and low-cost installation by clamping on the outside of existing carbon steel and copper pipes ranging in size from ½” to 2”. It’s designed to replace mechanical flow meters where liquid conditions tend to damage or impede mechanical flow meter operation.
