TIENet®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.

The 350 AV sensor is available with a 10m, 23m cable. For
greater distances, external connection via conduit, and con-
nection of additional TIENet devices, the TIENet Expansion Box
is available. Bulk TIENet cable may also be used for greater dis-
tances.
Figure 1-2 TIENet Model 350 Area Velocity Sensor
1.1.1 350 Velocity Operation The 350 area velocity sensor contains a pair of ultrasonic trans-
ducers. One transducer transmits the ultrasonic sound wave. As
the transmitted wave travels through the stream, particles and
bubbles carried by the stream reflect the sound wave back at the
sensor. The second transducer receives the reflected wave.
The sensor determines the frequency shift between the trans-
mitted and received waves. An increase or decrease in the fre-
quency of the reflected wave indicates forward or reverse flow.
The degree of change is proportional to the velocity of the flow
stream.
1.1.2 350 Level Operation The 350 sensor’s internal differential pressure transducer mea-
sures the liquid level. The transducer is a small piezo-resistive
chip that detects the difference of the pressures felt on the inner
and outer face.
The stainless steel outer diaphragm is exposed to the flow stream
through the ports under the sensor. The pressure felt on the
outer diaphragm is transferred to the outer face of the trans-
ducer. The inner face of the transducer is referenced to the atmo-
sphere through the internal vent tube that runs the full length of
the sensor cable.
The difference between the pressures exerted on the transducer
is the hydrostatic pressure, which is proportional to the level of
the stream above the transducer. The analog representation of
the hydrostatic pressure is digitized and sent to the Signature as
an RS-485 half-duplex signal.
