Level sensors are quite important in various industries as they have a wide range of applications. They’re commonly used in oil manufacturing plants, beverage and food manufacturing companies, and water treatment plants. They provide accuracy and precision, helping companies measure the exact amount of solid and liquid. The following blog discusses the importance of point-level sensors in more detail.

What Exactly Are Level Sensors?

Level sensors consist of any device that can be used to measure the level of a product in a particular vessel, tank, pipe or tubing. The sensors, like the non-invasive point liquid sensor, help distributors and manufacturers identify quantity of product that goes into each storage container. Point-level sensors also utilize different technologies, ranging from traditional means to gamma rays.

Importance of Level Sensors

There are many uses for point-level sensors like non-invasive point-liquid-level detectors. The primary function is to provide information regarding tank levels as a way to streamline the manufacturing processes. Companies should know how much material is in a silo or a tank to identify the amount of material needed, thereby cutting waste and getting the exact materials needed.

The robotics industry also uses point-level sensors to keep track of fluid levels. If fluid levels drop down to a certain threshold, the robotics systems can identify errors and stop operations. In the same manner, automated systems across industries rely on operations of hydraulics to identify the exact levels of oil reservoirs for maintenance and safety purposes.

Moreover, if there’s any leak in the system, the level sensor would help detect of such an issue. In this way, operations can stop before equipment fails or someone is injured. Hence, level sensors play a vital role when managing industrial operations.

Types of Level Sensors

Capacitance Level Sensors

These sensors basically use the dielectric constant (relative permittivity) in accordance with the type of the fluid. These sensors need a transmitter attached to the insulated or non-insulated rod to accurately measure the capacitance of the total material in the tank.

Pressure Sensors

As the name suggests, pressure sensors use a pressure gauge in order to measure the output of the pressure applied by a liquid in the tank. The pressure can be used to measure the column’s height above the sensor.

Laser, Ultrasonic, and Radar Sensors

These sensors have a sending and receiving unit, which can be transformed into a waveform. The wave travels through the fluid and measures the amount of time between sending and receiving. The detail over the time increment can then be used to measure the level of the product in the tank.


Point-level sensors have broad applications in various industries. They help manufacturers and distributors monitor the amount of product filled in each storage container. The correct type of level can significantly streamline many processes.

Importance Of Bubble Sensors to Prevent an Air Embolism

People love to play with bubbles, especially in bathtubs and plastic fills, but bubbles can become a threat in many instances & applications. For example, they can cause severe quality failures in semiconductor process equipment and 3D printing infusion. They can also be life-threatening in medical circumstances that require infusion pumps, blood flow monitoring, and hemodialysis. Thankfully, special sensors, also called bubble sensors, can detect bubbles using ultrasonic energy.

What Are Bubble Sensors?

Bubble sensors are devices used to detect bubbles in almost all tubing and fluid material used in medical devices. They detect bubbles in infusion lines, transfusion lines, and dialysis machines effectively. These air bubble detectors help prevent air embolism problems and maintain a steady flow.

What Is Air Embolism?

Air embolism occurs when a gas bubble enters the artery or vein. When this happens, gas bubbles restrict the movement of blood. It can cause a stroke, heart attacks, and several other health issues. Although the effect of air embolism is not discussed as much as it should, it is life-threatening.

Based on this, ultrasonic bubble detectors have become pretty helpful in the medical sector. They are used to prevent potentially fatal health issues like heart attacks and stroke. In medicine, bubble sensors are used primarily during blood transfusion, hemodialysis, and other operations that require the flow of liquid.

Types Of Bubble Sensors

There are two main types of bubble detector sensors used in the medical sector when treating patients. These sensors are photoelectric bubble sensors and ultrasonic bubble sensors. Although both sensors perform the same function, they are sometimes used for different operations.

Photoelectric Bubble Sensors

Photoelectric bubble sensors or optical bubble sensors are used for the non-invasive detection of air pockets and fluids in the tube. They can be effective for bubble detection for several types of liquids. However, there are known disadvantages in using optical technology such as susceptibility to environmental effects such as light and dust that interfere with long term sensor accuracy & reliability.

Ultrasonic Bubble Sensors

The ultrasonic bubble detector is a much better technology for detecting bubbles. It uses ultrasonic waves for bubble detection; however, the transmission of the ultrasonic waves differs between liquids and bubbles. Ultrasonic waves won’t be transmitted unless there is liquid in the tube. Ultrasonic bubble detectors are entirely non-invasive but have a significant advantage over photoelectric sensors. Unlike the photoelectric sensors, they don’t need further calibration during usage in the field and are not typically affected by most environmental conditions.

We are a leading manufacturer of all types of non-invasive fluid detection devices. We have been in the industry since 1981 and remain committed to providing safe and reliable products.

Use of Non-Contact Sensors for the Medical Industry

Countless processes and treatments of the modern medical industry require careful monitoring with the help of highly technological devices. For such devices, whether handling bodily fluids or external medications, levels of these substances must be sensed and measured accurately. To this end, a special sensor can accommodate many device sizes while taking accurate notes of the levels of substances like blood, insulin, and IV fluids. As the name indicates, a non-contact level sensor never touches the substances being monitored in a vessel or tube, nor does the ultrasonic signal affect the given fluid, maintaining hygiene and quality.

The Function

A medical sensor manufacturer designs its products to send out constant ultrasonic waves of vibration. Waves then bounce off the surface of a given substance and bounce back to the originating sensor. Medical establishments are able to use this in measuring and monitoring liquids by interacting with the results of the sensor. The sensor uses time measurements during the “trip” of one wave from the sensor and back. These results recorded in the non-contact level sensor are then compared to the speed of sound in order to determine what level a fluid has reached.

Sensor Types

There are stainless steel metal devices offered by sensor manufacturing companies. These are able to record moisture and temperature of their associated liquids, in addition to their level. As such, these innovations can be applied to a large variety of ends, spanning more industries than medical matters. In addition, industrial and medical customers can opt for plastic sensors. These are made from nylon or polypropylene, both known for their durability. Along these lines, the plastic versions are also especially resistant to the effects due to chemicals. Like their metal counterparts, these can also be used across a wide range of industries, apart from medical applications.

Additional Benefits

The range of measurement in his specialized sensors is significant. This typically allows for use in medical containers and devices from as small as 15mm to 300mm. However, it is possible to have devices specially designed and utilized for both smaller and larger sizes. These devices are also very easy to put in place, requiring only a strap to be attached to the outer container. Furthermore, these innovations can be used for both the continuous level sensors used in the medical field and the point level sensors essential to measuring the contents of tanks and farm silos.

Introtek is able to accommodate all non-contact sensor needs for a medical establishment with our ultrasonic technology. Call us today for information on how to incorporate our products for greater comfort, success, and safety in the workplace.

How Ultrasonic Sensors Work for Different Industries

Ultrasonic sensors are sensors that measure the distance between the target and the sensor. The technology is based on the principles of ultrasonic sound waves, which are not audible to humans. The sensor works by sending out sound waves, which bounce off the target and return to the sensor. The time it takes for the sound waves to return to the sensor is measured. An ultrasonic fluid level sensor can also be used to measure depth, temperature, velocity, pressure, acceleration, etc., by emitting waves that are sensed by an appropriate sensor.

Ultrasonic level sensors are commonly used for various industrial applications, because of their small size and power consumption. These sensors are mainly used in machinery, medical, aerospace, agriculture, security, automotive industries, and more.

How exactly are ultrasonic sensors used in specific industries?

The Smart Factory

Ultrasonic sensors are necessary to the automation process on a factory floor. The sensor is used to locate the position of an object by sending ultrasonic waves to detect objects within a detection zone. Ultrasonic sensors are positioned at various points to ensure that there are no blind spots. They are also used for item sorting, high-speed counting, robotic machine sensing, and liquid level controls.

Supply Chain and Warehousing Industry

The demand for efficient and accurate tracking of materials and items continues to grow. The supply chain and warehousing industry uses ultrasonic sensors for counting, item sorting, high-speed counting, robotic machine sensing, and liquid level controls. Ultrasonic sensors count the number of pieces per second as they pass down a conveyor line or through a port. Those ultrasonic sensors can be used for sorting and classifying objects, as well as monitoring the flow rate of a conveyor line. Ultrasonic level sensors are used to monitor levels in storage tanks or bins. With an array sensor, multiple ultrasonic sensors provide automatic control of bin levels without opening the top or doors of a bin.

Waste Management

Ultrasonic level sensors are used in waste management as well as recycling programs. In waste, they can monitor levels in dumpsters, compactors, and trash trucks to ensure that the proper amount is being disposed of. Ultrasonic sensors are particularly effective for compressed garbage because a user does not have to open the truck or bin to determine whether it’s full.

Energy Sector, Beverage, and Pharmaceutical Industry

Ultrasonic liquid level sensors measure liquid levels in storage tanks or silos, usually mounted on the outside. The ultrasonic device will send a sound wave into the liquid and then time how long it takes for the echo to return. This time is used to determine the liquid level. The Ultrasonic Liquid Level Meter provides users with reliable leak detection solutions by using these devices as leak detectors.

Critical Sensors for Hemodialysis

The kidneys are responsible for filtering and removing waste products from the blood. Hemodialysis is used for those with severe kidney disease to aid their filtering process. Blood is pumped out of the body and into the machine, where it passes through a network of small filtering tubes that simulate a human kidney.

A number of critical sensors are required for hemodialysis to be effective, including the blood leak detector. Different sensors are required for accurate monitoring of liquid flow, pressure, and temperature in both the patient’s blood and the circulating dialysate. They also allow for rapid detection of air bubbles present in either of the fluids.

Principles of Hemodialysis: Mechanical and Safety Monitors

The non-invasive blood leak detector is a key component of many modern-day hemodialysis machines. It functions to detect minute amounts of blood in clear fluids on plastic tubing to identify any blood leaks in the dialasyste line.

This mini blood component detector uses a light source with an optimum wavelength. If the blood traveling through the tubing of the dialysis machine exceeds this threshold, an alarm is triggered. This optical-based system is important to identify unwanted elements in the blood or dialysate to ensure maximum safety during hemodialysis.

Waste materials and fluid are able to pass through the membranes of the tubing into the dialysate, a clear fluid that flows in the opposite direction on the outside of the tubes. The filtered blood then travels back into the body.

Although complications with dialysis are rare, the blood leak detector is a major safety mechanism that every dialyzer machine requires. When small fractures of blood are present in the dialysate, it indicates a small membrane rupture in one of the tubes. This can be life-threatening to the patient, as a contaminated fluid may come into contact with the circulating blood.

The safety of dialyzers can be attributed to the incredible critical sensors and detectors that ensure the blood and dialysate are kept apart at all times. Contact Introtek to learn more.
