Bubble level sensors come in various types, each designed to meet specific application requirements. Understanding these types can help users select the most suitable sensor for their needs.
These sensors detect liquid levels in two different points within a container. This allows for more accurate level measurement. They create a difference between the two levels that can be compared. This means the bubble's position can indicate whether the liquid level has reached a specified height or not.
These sensors utilize the capacitance change caused by the bubble's presence or absence in a liquid. It distinguishes between gas and liquid. When the bubble appears in the liquid, it changes the capacitance.
On the other hand, the change is not present when the sensor is submerged fully in the liquid. This means capacitive sensors are suitable for measuring liquid levels that can erase errors.
They use visual indicators to show the sensor's level. This is good for hard-to-reach areas where it would be difficult to access the level directly. A remote bubble level sensor can be connected by wires. Or, it can communicate with a network wirelessly.
Indeed, this makes them more flexible than other types of sensors. People might use remote sensors in structures such as aqueducts to monitor water levels.
These sensors measure the tilt angle of an object or surface. They contain a liquid-filled tube with a bubble inside. The tube is sealed with a transparent material, usually a plastic lens. When the bubble moves to the top of the tube, it indicates the surface is level.
On the other hand, if the bubble is centered in the tube, it means the surface is tilted. Also, tilt sensors are often used in construction, surveying, and machinery to ensure proper leveling.
Bubble level sensors have many uses in industries that deal with liquids or need to know how much of something is inside a container. Here are some common industrial applications:
In water treatment plants, bubble level sensors monitor water and chemical levels in tanks and pipelines. This ensures processes like filtration, disinfection, and chemical dosing run smoothly.

Bubble level sensors are highly durable. This allows them to handle harsh conditions with ease. For instance, extreme temperatures, high pressures, and corrosive substances.
Proper installation of a bubble level sensor is crucial for accurate performance. This is since errors during installation can lead to incorrect readings and affect the entire system. Here are some steps on how to install bubble level sensors accurately:
Pick the right location for the sensor. This is done by identifying the point where the level needs to be measured. Here, try to avoid spots with high turbulence or near inlets and outlets. This is to prevent inaccurate readings caused by rapid liquid movement.
Before putting the sensor in place, ensure all the materials and equipment needed are available. Usually, the main tools needed are mounting brackets, screws, and a sealing compound. The sensors come with user manuals. It is advisable to follow the manufacturers' guidelines during the installation process.
Next, mount the sensor securely in the chosen location. Make sure it is in the right position and the bubble aligns with the marked reference line. This helps the sensor read the correct measurement.
The sensor should be installed onto pipelines or vessels using clamps or brackets.
For sensors that need to be submerged in liquids, install them horizontally above the liquid surface. This is to prevent them from getting fully submerged. On the other hand, if the sensor can dip into the liquid, install it vertically.
After securely mounting the sensor, connect it to the power source and control system. Most bubble level sensors have simple wiring systems. However, it is important to check the manufacturer's manual for guidelines on how the sensor is connected.
If the sensor uses wireless communication, ensure it is within the range of the receiving unit. Then, power the sensor on and check whether it is functioning and communicating properly. Finally, run a test and observe the sensor's readings while monitoring the liquid level in the process.
Maintenance of bubble level sensors is essential to preserve their accuracy and lifespan. Most importantly, maintenance should be done according to manufacturers' recommendations. Normally, maintenance involves inspection, cleaning, and calibration of the sensors as outlined below:
Regularly inspect the sensor for signs of wear, damage, or buildup. Users can do this by visually inspecting the sensor body and bubble chamber. This is to check for cracks, corrosion, or any other physical damage. Also, check for any residue or buildup that could interfere with the sensor's operation.
Residue buildup can affect sensor accuracy. Clean the sensor regularly to prevent this. Start by disconnecting the sensor from the power supply. Then, gently clean the sensor using appropriate materials. For example, use a soft cloth for general cleaning.
After cleaning, verify the sensor's calibration. Refer to the manufacturer's guidelines on how to calibrate the sensor. Normally, sensors may need periodic recalibration to maintain accuracy, especially after prolonged use or exposure to harsh conditions.
Keep an eye on sensor performance by checking its readings regularly. If the readings are inconsistent or drift over time, it may need recalibration or replacement. Also, record the sensor's performance data to help identify trends in functionality or accuracy over time.
Check all electrical connections to ensure they are secure and free from corrosion. This helps to prevent signal loss and inaccurate readings. Also, inspect wiring for signs of wear or damage, as faulty wires can affect sensor performance.
During maintenance, make sure to test the system's overall performance with other level measuring devices.
When dealing with bubble level sensors, ensuring their quality and safety is vital. So, here are some considerations that can help with this:
Manufacturers usually make bubble level sensors from stainless steel. This is because the material is highly resistant to corrosion. Corrosion resistance is an important factor since many liquids can cause corrosion. That will damage the sensors.
Many bubble level sensors work under high temperature and pressure conditions. Therefore, high-quality sensors should withstand extreme conditions without losing accuracy or functionality. This means that the sensors' components must be manufactured with thermal and pressure resistance.
To properly work during the installation process, keep an eye on the sensor's precision and repeatability. They are two critical factors to consider when selecting a sensor. The sensors should also have a fast response time to provide real-time level monitoring.
People frequently use bubble level sensors in hazardous environments while handling toxic or flammable substances. Ensure that the sensors meet industry-specific safety standards and certifications, such as ATEX, IECEx, or UL/CSA for explosive environments.
Good-quality sensors are durable enough to resist shock, vibration, and other mechanical stresses. These factors can affect sensor performance and even lead to failure. The sensors should also be able to operate in a wide range of temperatures, from extreme heat to freezing conditions.
Some sensors are non-invasive. They reduce the risk of contamination, especially in industries like food and beverages, pharmaceuticals, and chemicals. This makes them safer options for handling sensitive materials.
As mentioned earlier, sensors that contain hazardous liquids must comply with strict safety and reliability standards. These standards include explosion proof ratings.
Regular maintenance and inspection of bubble level sensors are essential to ensure accurate performance and prevent failures. When a sensor fails, it can cause dangerous situations such as overflows, spills, or even explosions.
People should always replace worn-out or damaged sensors immediately to prevent accidents. During replacement, ensure that the new sensor meets quality standards and the manufacturer's specifications.
Ans: Buyers should consider several factors when buying bubble level sensors. These factors will ensure the customers get the right sensor for their specific use cases. First, consider the sensor's application. Different industries have different requirements. So, knowledge of the application helps narrow the decision, especially when the purpose is industrial use.
Second, consider the mounting options available. This is because the mounting will determine where the sensor is installed, how flexible, and how easy it is to install. Third, consider the sensor's housing material. Materials like stainless steel and plastics come with varying levels of durability, corrosion, and chemical resistance. So, choose the one that will work best in the customer's environment.
Ans: Many users make errors when installing the sensors, affecting their performance. One of these errors is installing the sensors in locations with much liquid turbulence. Doing so will affect the sensor's ability to detect bubbles, leading to inaccurate readings. Moreover, failing to secure the sensor properly may cause it to move over time. This affects its ability to give correct results all the time.
Others forget to power the browser systems during installation. A powered-down system means new installs will not be detected. Moreover, not following the manufacturer's installation guidelines also has many negative effects. Users should also ensure that the sensor is compatible with the liquid in the system. Using an incompatible sensor will lead to corrosion, inaccurate readings, or total failure.
Ans: Regular maintenance helps the sensors stick around for a longer time. Moreover, it improves their accuracy throughout their lifespan. The sensors have tough exteriors that ensure they survive hard working conditions. Their interiors are also designed to tackle a wide range of bubbles. A good example is the ultrasound liquid level sensor. It is tough but still needs regular maintenance to keep working efficiently.
Ans: Usually, most bubble level sensors last around 3 to 5 years. This is especially when users take good care of them and do regular maintenance when needed. Some sensors can last up to a decade, though. The sensor's environment, the material it is made from, and the stress it goes through all influence how long it will last.
Ans: The sensor comes with an explosion-proof designation. This means it can withstand internal explosions without causing an external one. One of these features is an internal flame barrier. It is a barrier that cools the flame to a point where it cannot reignite outside the device.
Manufacturers also make these sensors with heavy-duty metal covers. The materials include things like cast aluminum, stainless steel, or steel with rated glass. This cover will help contain any explosion that may occur within the sensor. In the end, these sensors are tested in explosive environments such as mines and inside refineries.
