Level sensors in industrial containers and tanks
Level sensors are used to measure liquid levels in industrial tanks and containers. By recording the level of the liquid, they enable monitoring of filling, emptying and various process sequences in, for example, stainless steel and acid-resistant tanks.
The choice of level sensor and measurement technology depends on several factors, such as the characteristics of the liquid, temperature, pressure and accuracy requirements. Different solutions are used depending on whether it is a smaller tank or larger tanks in the process industry.
Process surplus offers tanks in stainless steel 304 and acid-proof 316/316L in various designs and sizes. Some tanks can be equipped with level sensors or be prepared for installation depending on the design and previous use.
For pressurized tanks, specific requirements apply according to applicable regulations, such as the PED Directive. Any inspection is carried out by an accredited inspection body and documentation is included where available.
Function and structure
Level sensors usually consist of:
- Sensor or float that detects liquid level
- Signal cable or wireless transmission to control system
- Mounting fixture for fixed installation in tank
- Any amplifiers or converters for signal processing
- Protection against overpressure, vacuum and corrosion
Materials and construction
Stainless steel 304 and acid-proof 316/316L tanks and vessels are widely used in industry due to their good corrosion resistance and suitability for hygienic applications, such as food and chemical.
Level transmitters, sensors and floats are selected based on the chemical properties of the liquid, temperature and other process conditions, making it possible to customize the level measurement to the application at hand.
Processöverskott offers tanks in stainless steel and acid-proof design in different sizes and constructions. Some tanks can be equipped with level sensors or be prepared for installation depending on previous use and design.
For pressurized tanks, specific requirements apply according to applicable regulations, such as the PED Directive. Any inspection is carried out by an accredited inspection body, and documentation is included where available.
Pressurized and atmospheric solutions
Level sensors can be installed in both pressurized and atmospheric tanks. Pressurized tanks require reinforced mounting points and seals that can withstand working and design pressures.
Applications in industry
- Food industry – level control of syrups, oils and liquids
- Chemical industry – safe level measurements of corrosive chemicals
- Pharmaceutical production – precise level monitoring in sterile processes
- Water treatment – continuous measurement of chemicals and water level
Technical options and equipment
- Continuous or point level sensors
- Analogue and digital signals
- External displays and alarm connections
- Float sensors for viscous or foaming liquids
- Integration with PLC and SCADA systems
Volumes and capacity
Level sensors are used in tanks from 100 liters up to 250 000 liters. The location and type of sensor is selected according to the height of the tank, the density of the liquid and process requirements to ensure accurate measurement.
Advantages of level sensors
- Automatic and safe level control
- Reduces the risk of overfilling or idling
- Reduces the need for manual monitoring
- Available in new and used tanks
- CE marking and PED compliance

Processöverskott offers both new and used stainless steel tanks in stock for different types of industrial needs. The tanks are available in several volumes and designs depending on the area of use and previous application.
Some tanks may be equipped with level sensors or prepared for installation. Documentation and CE marking may be included where available.
Many tanks are available for immediate delivery and are sold as is, with the possibility of further control or inspection if necessary.
Choosing the right level sensor
The choice of level sensor depends on several factors, such as the volume of the tank, the viscosity of the liquid, the chemical properties and the pressure class, if any. Different applications may require different types of sensors and measurement techniques to achieve reliable level measurement.
Process surpluses can contribute information about the tank’s design and conditions as a basis for choosing a suitable solution. The choice of sensor, location and possible integration with control systems is usually done in consultation with the supplier or technical specialist. For pressurized applications, special requirements apply under current regulations, such as the PED Directive.

Frequently asked questions about level sensors in industrial containers
How do level sensors work in industrial containers?
Level sensors detect liquid levels in tanks through sensors or floats and send signals to control systems. This enables the monitoring of filling, emptying and level control in different types of processes.
Process Surplus offers tanks in stainless steel 304 and acid-proof 316/316L in various designs. Some tanks can be equipped with point or continuous level sensors depending on the design and previous use.
For pressurized tanks, specific requirements apply according to applicable regulations, such as the PED Directive. Documentation and CE marking may be included where available.
What types of level sensors are available?
Point level sensors give alarms at a certain level, while continuous ones give the exact level curve. Analog and digital signals can be connected to PLC or SCADA. The choice depends on tank volume, fluid viscosity and process requirements.
Can level sensors be used in pressurized tanks?
Yes, level sensors can be installed in pressurized and atmospheric tanks. Pressurized solutions require reinforced mounting points and seals that can withstand working and design pressures.
What materials are used?
Stainless steels, such as stainless 304 and acid-proof 316/316L, are widely used in level sensors and mounting fixtures due to their good corrosion resistance and suitability for hygienic applications.
Floats and sensors are customized according to the chemical properties of the liquid and the temperature requirements, making it possible to choose the right solution for different types of industrial processes.
Can used tanks be equipped with level sensors?
Yes, used tanks can in many cases be equipped with level sensors depending on the design, size and application of the tank. The possibility to install level sensors varies depending on the previous design and the adaptations required.
The choice of level sensor is influenced by, among other things, the characteristics of the liquid, temperature and possible pressure in the tank. Installation and customization is usually done in conjunction with customer needs and may require complementary solutions.
For some tanks, e.g. from specific manufacturers or with specific equipment, CIP may also be possible. However, this depends on the design and previous use of the tank.
