Model 350 Area Velocity Sensor
Section 1 Introduction
The Teledyne ISCO TIENet 350 Area Velocity Sensor measures
flow stream average area velocity and liquid level. The Sig-
nature
®
Flow Meter uses this information to calculate the flow
rate and total flow of the stream. To operate with the 350 sensor,
the Signature requires software version 1.18 or later.
1.1 Description
The 350 sensor is mounted in the flow stream, normally at the
bottom of the channel. It measures average velocity using con-
tinuous ultrasonic sound waves to produce a Doppler effect, in
which the frequency of a wave (such as sound) passed between
two bodies is relative to the motion of each. As they move nearer
to each other, the frequency increases; as they move apart, the
frequency decreases.
The 350 sensor measures liquid level using an internal differ-
ential pressure transducer.
