• Understanding Ultrasonics
Ultrasonic sensors use a transducer to transmit bursts of ultrasonic sound
waves. Each burst contains a series of pulsed sound waves that emit in the
shape of a cone, reect o the target, and are detected by the sensor. The me
required for the sound waves to travel to and from the target is converted into
a distance measurement by the sensor. Ultrasonic sensing is aected by several
factors including the target surface, distance, size, and angle. The following
consideraons will help ensure the best possible target condions.
Surface
The ideal target surface is hard and smooth. This type of surface will reect a
greater amount of signal than a so or uneven surface. Sound wave absorbent
materials, such as granules and powders, will reduce the operang range of the
sensor and decrease measurement accuracy.
Distance
Sound wave aenuaon increases as the distance traveled increases.
Therefore, targets at longer ranges require beer reecve characteriscs than
targets that are closer to the sensor.
Size
A large object will have a greater surface area to reect the signal than a
smaller one. Therefore, a large target will be detected at a greater distance than
a small target. The surface area recognized as the target will generally be the
poron closest to the sensor.

Angle
The inclinaon of the object’s surface in relaon to the sensor face will aect
the strength of the reected sound waves. Surfaces perpendicular to the sensor
will reect more signal directly back to the sensor. If a surface is more than a
few degrees o perpendicular, enough of the signal will be reected away from
the sensor that the target will not be detected. Generally speaking, a target
angle greater than 5 degrees o perpendicular will not be detected. The target
angle becomes increasingly crical as the distance to the target increases.
Environmental Condions
Temperature, humidity, vapors, dust, and pressure can aect the sensor’s
performance. APG ultrasonic sensors are designed to compensate for many of
these condions. However, if the condions are extreme, sensor performance
can be degraded enough to require the use of a longer-range sensor than
normal condions would require. Ultrasonic sensors may not be suitable for
applicaons with heavy chemical vapors (such as solvents or gasoline), heavy
dust or when signicant surface foam is present.

NOTE: Slling pipes are an excellent soluon for liquid level
applicaons where an unobstructed path to the target is not feasible
(see slling pipe mounng on page 9 for details).
• When mounng outdoors, it’s best to shade the sensor from direct
sunlight. Direct sunlight can warm the sensor housing above the ambient
temperature causing false temperature readings and overcompensaon by
the sensor.
• Installaon
Proper sensor mounng is crical for successful operaon of an ultrasonic
sensor. Using the following guidelines can help ensure trouble free installaon
and operaon:
• Ensure that the sensor face is perpendicular to the target surface. If the
target is more than a few degrees o perpendicular, it may not be
detected. Targets at greater distances will require more precise sensor
alignment.
• Mount the sensor in a locaon that provides an unobstructed column
of air from the sensor to the target. The required width of the air
column depends on several factors, including the angle and reecve
characteriscs of any potenal targets on the edge of the column, the
sensivity seng of the sensor, the maximum distance to the target, and
the reecve characteriscs of the target itself. Generally speaking a 3 to 4
foot diameter unobstructed column is sucient even at longer ranges.

• Always mount above the highest ancipated target level by at least the
published minimum blanking distance. If a target enters into the blanking
area, error in the detecon will occur. It is always advisable to allow for
sucient headroom to ensure that the target does not enter the blanking
area.
• Generally it is advisable to mount the sensor away from any vessel ll
spouts. However, if heavy foam is expected, it is oen helpful to mount the
Sensor near a ll spout where the foam is being dispersed.
• Avoid mounng the sensor in the direct center of a tank with a signicantly
domed top. A domed top can act as parabolic dish, amplifying small
undesired signals that may be present inside the tank.
• Avoid mounng the sensor in close proximity to tank walls, especially on
tanks with corrugated walls or in applicaons where product buildup on
the tank walls may occur.

Stand Pipe Mounng
Stand pipes are used to provide headroom at
the top of a tank when the target is expected
to come closer to the sensor than the
minimum blanking distance. It’s very crical
that the stand pipe be installed perpendicular
to the target. This is especially important
on longer range applicaons. The pipe must
have smooth walls (no joints) and no burs or
obstrucons. If possible, cut the end of the
pipe at a 10°-45° angle (see drawing). Use
the largest diameter pipe and shortest length
possible. As a general rule, the diameter of
the pipe should be 1/2 the length. The pipe
ID must remain the same through it’s enre
length.
Slling Pipe Mounng
Slling pipes provide access to dicult areas
and help eliminate problems with foam.
The pipe must have smooth walls (no burs
or joints). Because the sound waves will
concentrate and propagate down the inside
walls of the tube, any irregularies on the
tube walls may produce echo returns and
cause false readings. Slling pipes are limited
to liquid targets that will not leave heavy
deposits on the tube walls. Because the
sound waves are conned inside the pipe,
it is usually necessary to greatly reduce the
sensors sensivity and pulses sengs. A vent
hole must be provided at the top of the pipe.
Be sure to keep the vent hole inside of the
blanking area.
