Measure flow from outside a pipe. This new Portaflow PT500 transit-time flowmeter is designed for clean liquids like water, oils and most chemicals. It is recommended for troubleshooting, spot checks and balancing flow. Clamp-on sensors mount on the outside of plastic or metal pipes, and ultrasonic signals are injected through the pipe between the two sensors. It works on any pipe diameter from 0.51 to 78 in. OD.
