Continuous Level Measurement – Precise Monitoring of Liquids with Reed Level Sensors
How Does a Reed Level Sensor Work?
Level measurement plays a crucial role in numerous applications. It enables the continuous monitoring of liquids and chemicals, ensuring the smooth operation of systems and facilities. Accurate detection of fill levels helps prevent failures by providing early warnings of critical conditions—whether the level is too low or too high.
Moreover, level measurement contributes to increased process efficiency. Refill times can be precisely calculated, avoiding unnecessary downtime. By automating such processes, both costs are reduced, and operational safety is enhanced. Continuous monitoring ensures that both small containers and large-volume tanks are always optimally utilized.
Reed sensors continuously measure the exact fill level. Our sensors are used in a wide range of sectors where quality, reliability and continuity are all in demand.

Technologies and Methods of Level Measurement
Level measurement can be broadly divided into two categories: continuous level measurement and limit level detection. While continuous measurement precisely determines the fill level across an entire range, limit level detection is used to identify specific conditions such as “empty” or “full.” Both methods have their justification and are applied depending on the specific use case.
Various technologies are used in sensors for continuous level measurement:
- Reed Measuring Transmitters: These sensors provide continuous and precise level detection and can be used in chemically demanding media as well as in space-saving designs. They deliver reliable data that can be utilized for real-time analysis and automation.
- Hall Technology: This technology utilizes the Hall effect to measure fill levels accurately. Hall sensors rely on thin, doped semiconductor layers that generate a voltage proportional to the magnetic flux density when exposed to a magnetic field.
The choice of the specific method and technology depends on the medium, environment, and application.
Reed Electronics AG Level Probes: Precision and Reliability
Our level probes enable precise detection of fill levels from 0 to 100% and convert the measured fill height into electronic signals that can be used for a wide range of applications.
A key advantage of our sensors is their flexibility. They can be individually adapted to different container sizes, making them a reliable solution for a variety of applications—whether for small containers in laboratory technology or larger tanks in the chemical industry.
The data obtained from the measuring transmitter provides valuable information that can be used, for example, to control pumps or similar equipment, ensuring that an emptying tank is refilled in time.
Versatile Level Measurement Thanks to Special Features
Sensors from Reed Electronics AG are specifically designed to operate reliably even in aggressive media such as 30% hydrochloric acid, chlorine, or other chemical substances. This resistance makes them an ideal choice for demanding applications in the chemical and laboratory sectors.
Additionally, our sensors feature a compact design, enabling their use even in confined spaces. This is particularly beneficial in fields like medical technology or analytical devices, where space for measuring instruments is often limited.
High-quality materials and robust construction ensure that Reed sensors have a long lifespan and remain durable even under continuous operation. Their reliability is backed by years of testing in aggressive environments.
One of our long-standing customers has been using our sensor in 30% hydrochloric acid in his laboratory for more than seven years, without interruption. He told us that all of the other material in the acid has since dissolved – everything except our sensor, which is still working flawlessly and consistently.

Examples of fill-level monitoring applications
The sensors are designed to save space and can be customised to fit the size of the container in question. This, coupled with their resistant construction, makes them a reliable option for use in confined spaces and in abrasive media, such as in the areas of medical or laboratory diagnostics.
Data determined by the sensors provide information on when the next refill is to be expected and, if needed, can reorder the necessary fluids as part of a fully automated process.
Additional Application Areas for Level Sensors
Chemical Industry & ATEX (Explosion Protection)
In the chemical industry, the requirements for level sensors are particularly high. They must not only operate with precision but also function reliably in demanding media. Our level sensors meet these requirements thanks to a wide range of materials that allow adaptation to specific application areas. Additionally, we offer sensors for ATEX environments, including a conformity declaration for explosion protection.
Biotechnology & Laboratory Technology
The biotechnology and laboratory sectors impose strict demands on precision and durability, especially in level measurement of chemicals and liquids. Level measurement is used here to continuously monitor critical values and ensure that all process steps run smoothly.
By accurately measuring the remaining liquid quantities, faulty analyses due to liquid shortages can be avoided. This not only increases the efficiency of the devices but also prevents costly failures.
Medical Technology
Precision in level measurement is crucial in medical technology, as incorrect measurements can directly impact patient safety and analysis results. Compact sensors are ideal for devices with limited space, such as infusion pumps or analytical instruments.
Mechanical Engineering
In mechanical engineering, robust and flexible level sensors are required to ensure precise monitoring even under harsh environmental conditions. Typical applications include monitoring coolant, lubricants, and hydraulic fluids. Thanks to their durable design and high reliability, our sensors help reduce downtime and increase machine efficiency.
