TIENet® Model 310 Ex
Ultrasonic Level Sensor
Section 1 Introduction
The Signature® Flow Meter uses the TIENet 310 Ex Device to
provide non-contact liquid level measurement. The flow meter
has built-in level-to-flow conversions that cover the majority of
open channel flow measurement situations.
1.1 Description The ultrasonic sensor is mounted over the flow stream. The flow
meter measures the time interval between transmission of a
sound pulse from the sensor, and receiving its echo off the surface
of the liquid, to determine the level of the stream.

Section 1 Introduction

This non-contact measurement method reduces the frequency of
maintenance, and is ideal for applications where the flow may
contain chemicals, grease, silt, or suspended solids.
1.2 310 Ex Sensor Design The ultrasonic level sensor consists of a housing with a single
transducer that is both pulse transmitter and echo receiver. A
temperature sensor within the housing measures the ambient
temperature, and a microprocessor automatically compensates
for speed-of-sound changes due to any changes in air temper-
ature.
The 310 Ex is available with a 10m, 23m, and special order to
150m or less cable lengths with or without connectors. 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 1-2 310 Ex Ultrasonic TIENet Sensor with
unterminated leads (l) or TIENet plug (r)
1.3 Operation The sensor emits multiple ultrasonic pulses per second. Between
pulses, the transducer switches from transmitter to receiver.
When the transducer receives the echo from the water’s surface,
the sound energy is converted into an electrical signal. The
signal is then amplified and processed by the Signature flow
meter into an “echo-received” signal. The time between the trans-
mitted pulse and the echo-received signal is proportional to the
distance between the transducer and the liquid surface. This dis-
tance in turn determines the liquid level used to calculate flow.

1.5 Accessories Accessories used in sensor installation are briefly described
below. Refer to the next section for ordering information.
Note
Only the Wall Mount Bracket is approved for use in classified
hazardous locations. Other accessories must undergo a haz-
ardous location evaluation in order to fulfill safe installation
requirements.
Spreader Bar – The Spreader Bar is an expandable pipe for
suspending equipment inside a manhole. Outward spring
pressure secures it against the manhole walls, like a shower
curtain rod. Depending on your application, you can then
suspend the 310 Ex TIENet Device, or the Signature Flow Meter
itself, from the bar.
Cable Straightener – The cable straightener is designed for
use in installations where the transducer is suspended by its
cable only, such as from the Spreader Bar. The straightener helps
hold the transducer vertically plumb, thereby stabilizing
alignment.
Cable Clamp – The cable clamp is used with the Spreader Bar
to secure the mounting of the sensor.
Wall Mount Bracket – This device lets you install the ultra-
sonic level sensor on a convenient nearby wall over a flow
stream, such as the side of a bridge, or other structure.
Floor Mount – The Ultrasonic Floor Mount is a collapsible
metal stand attached to the floor, for extending the sensor out
over a flow stream.
Ultrasonic Calibration Target – This option is designed to
make calibration of the level sensor more accurate during the
installation process by letting you calibrate the level sensor from
outside the manhole.
Sunshade – The ultrasonic sunshade is a white plastic cap that
fits over the top of the ultrasonic transducer. Its purpose is to
keep sunlight from heating the body of the level transducer and
introducing temperature errors to the internal temperature com-
pensation.

TIENet® Model 310 Ex Ultrasonic
Level Sensor
Section 2 Installation and Setup for Signature
The Signature Flow Meter does not have to be mounted near the
flow stream. You can install the flow meter itself at a convenient,
protected location and route the sensor cable to the measurement
point. Proper installation of the 310 Ex sensor is critical for
accurate measurement.
2.1 Sensor Installation
Considerations
Measurement accuracy can be affected by a number of site
factors that should be taken into consideration when selecting
the location for the sensor. If the sensor cannot obtain a valid
reading, an asterisk (*) will appear next to the displayed level,
indicating there is an error.
2.1.1 Beam Angle The 310 Ex sensor has a 10° beam angle, forming a cone whose
apex is the ultrasonic transducer. The sensor can only detect sur-
faces within this cone. Narrow channels can result in false echoes
and incorrect level readings off the walls and sides of the
channel. For preventive measures, see Section 2.5.2 Mea-
surement Setup, and the programming steps in Figure 2-14.
The beam becomes narrower at shorter distances, which can
increase difficulty in detecting the return echo. If the beam is too
wide, the sensor may pick up signals from unwanted surfaces,
such as the walls of the channel.
Sensor elevation is highly specific to the particular site.
2.1.2 Humidity Conditions of extremely high or low humidity can cause detection
to occur either earlier or later than under normal conditions. A
drop in water level, normally compensated for by the sensor’s
interval-based amplifier, may produce errors in echo detection.
Additionally, water droplet condensation on the bottom surface of
the sensor can cause measurement errors.
2.1.3 Surface Solids, foam, oil, and turbulence can all absorb or weaken the
ultrasonic pulses, causing errors in detection. Foam or oil on the
surface of the stream can produce false level readings.
2.1.4 Temperature Changes in ambient temperature significantly affect the velocity
of sound. If ambient temperature changes rapidly, there may be a
delay before the 310 Ex’s temperature sensor can activate tem-
perature compensation.
If the sensor will be installed outdoors in direct sunlight, use a
sunshade to prevent heating of the sensor housing.

TIENet® Model 310 Ex Ultrasonic Level Sensor
Section 2 Installation and Setup for Signature
2-2
2.1.5 Waves Waves on the surface of the flow stream can deflect the ultrasonic
signal, causing erroneous readings or total loss of signal. The
Signature Flow Meter software is able to reject occasional
readings that deviate substantially from normal.
2.1.6 Wind Strong winds can significantly reduce the strength of the return
echo. Narrow beams can result in the sound being blown away;
likewise, greater distances to the flow stream surface are more
subject to distortion in strong winds.
2.1.7 Hazardous Locations Installation in classified hazardous locations must meet specific
conditions in order to fulfill safety requirements. Installation
must be performed only by trained, qualified personnel. Refer to
Section 2.4 Installation in Hazardous Locations for complete
information.
2.2 Connecting the Cable External TIENet devices such as the 310 Ex are all connected to
the Signature flow meter in the same manner. These connections
usually use conduit or cord-grip cable fittings for permanent
mounted meter or with TIENet receptacle for portable meters.
Multiple external TIENet devices can be connected simultane-
ously.
Refer to your Signature flow meter manual for instructions on
accessing the instrument’s interior components.
Note
The steps that follow include instructions for installing cord-grip
fittings. Some applications will require cables to be routed
through user-supplied conduit. Conduit with a minimum 3/4"ID
is suggested for unterminated sensor cables and conduit with
minimum 1-1/2” ID is suggested for straight runs for sensor
cables with connectors.
2.2.1 Permanent Meters
Note
Before proceeding, ensure that the flow meter has been dis-
connected from mains power.

The SHIELD wire is the bare drain emerging from the foil
shield around the YELLOW and BROWN wires. The
BRAID-DRAIN wire is the bare drain emerging from the sur-
rounding braided shield inside the cable jacket. It is not neces-
sary to prevent the two braids from coming into contact with
each other.The drain wires need to be kept very short.

6. Gently tug the cable downward, to remove any slack within
the enclosure, taking care not to put any stress on the con-
nection.
7. Tighten the cord grip sealing nut.
CAUTION
If you are using conduit instead of the cord-grip fitting, the con-
duit must be sealed to prevent harmful gases and moisture
from entering the Signature enclosure. Failure to seal conduit
could reduce equipment life.
8. Close the front panel and fasten it shut with the two Phil-
lips screws.

2.2.2 Connecting to
Signature Portable via
a TIENet Receptacle
The optional external TIENet devices compatible with the Sig-
nature Portable (and Signature) all scan into the hardware in the
same manner. A scan is required anytime a new TIENet device is
added.
Multiple TIENet devices can be connected simultaneously to the
same Signature Portable Flow Meter. The following TIENet
devices will attach to the TIENet receptacle:
• Ultrasonic Level Sensor

TIENet® Model 310 Ex Ultrasonic Level Sensor
Section 2 Installation and Setup for Signature
2-6
• Area Velocity Sensor
• 301 pH Interface
• LaserFlow
• 306 Sampler Interface
Connecting a TIENet plug
to the Signature Portable
To connect the TIENet plug from the sensor to the TIENet Recep-
tacle:
1. Align the connectors and push together (Figure 2-6).
2. After the physical connection is made, a scan must be per-
formed for the device to be recognized.
For additional TIENet connections, use the TIENet Y-cable or
alternately an Expansion Box.
O-Ring and Lubrication
for the TIENet receptacle
1. Coat the O-ring’s sealing surface with a silicone lubricant.
CAUTION
Do not use petroleum-based lubricants. Petroleum-based
lubricants will cause the O-ring to swell and eventually deterio-
rate. Aerosol silicone lubricant sprays often use petro-
leum-based propellents. If you are using an aerosol spray,
allow a few minutes for the propellent to evaporate before pro-
ceeding.
2. Align and insert the connector. The sensor release will
“click” when the sensor connector is fully seated.
3. Connect the two caps together.
Figure 2-6 How to connect a TIENet plug to the Signature
Portable
2.3 Sensor Installation The mounting location of the ultrasonic level sensor depends on
the type of primary measuring device (such as a weir or flume),
and on the method of level-to-flow conversion used. Refer to the
Isco Open Channel Flow Measurement Handbook included with
your Signature flow meter, or to instructions provided by the
manufacturer of the primary device, for detailed information
about locating the measuring point.
