Certification
Canadian Radio Interference-Causing Equipment Regulation, IECS-003, Class A:
Supporting test records reside with the manufacturer.
This Class A digital apparatus meets all requirements of the Canadian Interference-Causing
Equipment Regulations.
Cet appareil numérique de classe A répond à toutes les exigences de la réglementation canadienne
sur les équipements provoquant des interférences.
FCC Part 15, Class "A" Limits
4 English
Supporting test records reside with the manufacturer. The device complies with Part 15 of the FCC
Rules. Operation is subject to the following conditions:
1. The equipment may not cause harmful interference.
2. The equipment must accept any interference received, including interference that may cause
undesired operation.
Changes or modifications to this equipment not expressly approved by the party responsible for
compliance could void the user's authority to operate the equipment. This equipment has been tested
and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC rules.
These limits are designed to provide reasonable protection against harmful interference when the
equipment is operated in a commercial environment. This equipment generates, uses and can
radiate radio frequency energy and, if not installed and used in accordance with the instruction
manual, may cause harmful interference to radio communications. Operation of this equipment in a
residential area is likely to cause harmful interference, in which case the user will be required to
correct the interference at their expense. The following techniques can be used to reduce
interference problems:
1. Disconnect the equipment from its power source to verify that it is or is not the source of the
interference.
2. If the equipment is connected to the same outlet as the device experiencing interference, connect
the equipment to a different outlet.
3. Move the equipment away from the device receiving the interference.
4. Reposition the receiving antenna for the device receiving the interference.
5. Try combinations of the above.
Product overview
The ultrasonic level sensors measure the flow level and calculate the flow rate in open channels. The
flow rate is calculated based on the flow level and the primary device or the flow level and the
velocity supplied by a velocity sensor.
Status indicator light
When the sensor is connected to a flow logger and taking a reading, the status indicator light of the
sensor is on. Refer to Figure 1 on page 6 and Figure 2 on page 6. Refer to Table 1 for the light
color descriptions.
Table 1 Status indicator definitions
Light color Description
Red No echo is found (echo loss).
Green Echo is found.
Flashing green The measurement target is too near the sensor (within 6.35 mm (0.25 in.) of the sensor
minimum distance).
Theory of operation
The flow level is measured by the ultrasonic sensor. The ultrasonic sensor makes a pulsed
ultrasound wave which is sent towards the water surface. The ultrasound wave reflects off of the
water surface and the echo is received back by the sensor. The distance is the measured time it
takes for the ultrasound wave pulse to go from the water surface to the sensor. The measured time is
multiplied by the speed of sound at the ambient temperature of the air below the sensor. The sensor
measures the ambient temperature for accuracy.
Product components
Make sure that all components have been received. Refer to Figure 1 and Figure 2. If any items are
missing or damaged, contact the manufacturer or a sales representative immediately.

Multiple hazards. Only qualified personnel must conduct the tasks described in this section of the
document.
Site installation guidelines
For the best sensor performance, obey the site installation guidelines in Table 2.

Table 2 Site installation guidelines
Guideline Details
Do not hang the sensor by the sensor cable. The sensor cable may stretch and cause measurement
errors.
Prevent the sun from shining directly on the sensor. Intense, direct sunlight on the sensor will increase the
temperature of the sensor housing higher than the ambient
air temperature. This can cause inaccurate measurements.
For the US9001 (downlooking) sensor, make sure
that the lowest mounting nut is more than 6.4 mm
(0.25 in.) from the sensor face. Refer to Figure 3.
If the mounting nut is near the sensor face, level spikes
can occur at extreme temperatures.
Hand tighten the hex nut, then tighten ½ turn. Do not
overtighten the hex nut or the isolation gasket will not
decrease vibrations.
Prevent strong winds and air currents from blowing
directly under the sensor.
The strength of the ultrasonic signal is decreased by the
wind.
Install the sensor so that the ultrasonic signal does
not hit the sides of a small pipe or narrow
flumes/channels.
The ultrasonic signal emits a half beam angle of 6 °. Refer
to Figure 4 and Figure 5. Set the minimum and maximum
distance for the measurement target to prevent false
echoes and incorrect level measurements. Refer to the
FSDATA Desktop documentation to change the application
settings.
Install the sensor sufficiently high above the surface
of the water so that it does not go under the water
when the level increases.
The speed of sound in water is much faster than in air. A
sensor that is under the water will give unusual values.

Installation setup
From the bottom of the sensor, the ultrasonic signal expands as it moves away from the sensor.
Install the sensor so that the ultrasonic signal does not hit the walls of the pipe or the top of the
channel.
8 English
When the installation is above a narrow channel, do not install the sensor too high because the beam
may be wider than the channel. This can cause false echoes from the tops of the channel walls
rather than from the water surface. To prevent false echoes, find the applicable sensor height so that
the entire beam falls within the channel and does not hit any obstructions.
Select the applicable sensor height:
1. Take the measurements. Refer to Figure 6.
2. Calculate the angle from the axis, Θ = arc tan × (D2/D1) ≈ 80.5 × (D2/D1).
3. To avoid interference from outside obstructions, make sure that the calculated angle from the axis
is less than the half beam angle (6 ° typical) of the sensor.
Figure 6 Sensor height selection
Install the sensor
Install the ultrasonic sensor so that it is over the center of the flow stream and the sensor face is
parallel with the flow. The sensor face should be parallel with the flow, so that the signal is
perpendicular to the flow and the signal echo does not bounce off the channel walls. The signal
bouncing off the wall may cause erratic readings or a complete echo loss.
The ultrasonic sensor has several mounting hardware options. Refer to Figure 7 and Figure 8. Refer
to the instructions supplied with the mounting hardware for installation information.

Figure 7 Mounting hardware options – US9001
Figure 8 Mounting hardware options – US9003
Connect to a flow logger or sampler
Connect the cable to a flow logger or sampler. Refer to the flow logger or sampler documentation for
instructions.
Install the sensor with a primary device
A primary device is a hydraulic structure, such as a flume or weir, that has a known level-to-flow
relationship. The ultrasonic sensor measures the level of liquid in a channel that contributes to flow
(referred to as the "head") and the flow logger calculates the flow rate based on the head-to-flow
relationship of the primary device.
Note: As an alternative, the flow logger can calculate the flow rate based on the level of liquid in the channel and
the area velocity supplied by a velocity sensor. The flow rate calculation method is selected in the Flow Method
field.
