Ultrasonic Level Sensor With Continous Ultrasonic Level Measurement
Of Fluids For Medium Range Applications
1. Application:
The series is an integrated two-wire ultrasonic level meter
continuous contactless liquid level measurement of liquids and
solids. It consists of probes and electronic devices, both of which
are leak-proof structure. This series of products can be widely
used in metallurgical industry,
chemical, electricity.

3. Advantages And Disadvantages
There are some advantages of ultrasonic level measurement which are
given below
- The ultrasonic level measurement is suitable for measurement in
liquid and solid.
- It is simple in construction and design.
- It does not require contact with processed material.
- It provides continuous level measurement.
- It has high accuracy.
- The sensitivity is high.
There are some disadvantages of ultrasonic level measurement which
are given below
- The ultrasonic level measurement is comparatively expensive.
- If heavy foam is present on the surface it acts as an absorbent
which creates errors.
4. Mounting Tips
Proper mounting is critical for the successful operation of an
ultrasonic sensor. Mounting mistakes are one of the most common
installation pitfalls with ultrasonics. However, it doesn’t have to
be difficult.
Here are a few practical guidelines that can help ensure trouble
free installation for your ultrasonic level sensors.
- Make sure the face of the sensor is perpendicular to the target
surface. If the sensor is a few degrees off perpendicular the
target may not be detected.
- Mount the sensor in a location that provides an unobstructed column
of air from the sensor to the target. Generally speaking you need a
3-4 foot diameter unobstructed column even at longer ranges.
Stilling wells provide a good solution for liquid level
applications where an unobstructed path to the target is difficult.
- Always mount the sensor above the highest anticipated target level
by at least the minimum blanking distance. The blanking distance is
usually between 4 – 12 inches depending on the model sensor you are
using.
- Mount the sensor away from any fill spouts. Mounting too close to
the spout could result in false readings. White noise can also be a
problem, as it can interrupt the sound wave.
- Avoid mounting the sensor in the direct center of a tank if there
is a domed top. The shape of the top could amplify small undesired
signals inside the tank.
- Mount the sensor away for tank walls especially if the walls are
corrugated or if there will be product buildup on tank walls.
- If the sensor will be mounted outdoors try to shade the sensor from
direct sunlight. This can harm the sensor housing and cause
overcompensation for temperature as the sensor heats up.
