Portable Clamp On Ultrasonic Flow Meter
I. Introduction
II. Working Principle
The external clamp type or pipe section type ultrasonic flow meter
is based on the principle of "velocity difference method" to
measure the liquid flow in the pipe. It adopts advanced multi pulse
technology, digital signal processing technology and error
correction technology, so that the flow meter can adapt to the
environment of industrial field, and the measurement is more
convenient, economical and accurate. The products have reached the
advanced level at home and abroad, and can be widely used in the
fields of petroleum, chemical industry, metallurgy, electric power,
water supply and drainage, etc.
