FDT-21W ultrasonic ﬂowmeter is

designed to measure the ﬂuid

velocity of liquid in a full/closed

pipe. It is a measurement system

which is both easy to install and

use. The FDT-21W operates

according to the difference in the

transit time of ﬂight measured, and

determines the ﬂow velocity by

measuring the travel time of a pulse

from one transducer to the next.

Flow in the same direction takes

less time to travel to the second

transducer than does ﬂow in the

opposite direction. Electroacoustic

transducers receive and emit brief

ultrasonic pulses through the liquid

of the pipe. Transducers are

vertically placed at both sides of the

measured pipe. Sensors are placed

FDT-21W shown smaller than actual size.

on the pipe and fastened by means

of a clamp. The display will quickly

show the ﬂow velocity. The FDT-21W

can be used for metallic, plastic and

rubber tubes.
