Portable Noncontact Flowmeters

Often used to pinpoint flow issues, these flowmeters clamp onto pipe, so you can spot-check the flow rate at different points without disassembling your system. They measure by tracking the time it takes for ultrasonic waves to pass through your liquid, so they don’t need to come into contact with your liquid. As a result, they can be used with a wider range of liquids than other flowmeters.
