Modern industrial plants cannot operate without precise monitoring of liquid levels in tanks, pipelines, and other technological systems. At Onninen, as market leaders in installation, we understand how crucial this issue is for the safety of production processes and the economic efficiency of enterprises. Our years of collaboration with industrial plants show that modern liquid level sensors are not just monitoring tools, but a fundamental element of resource management and process optimization.
From our experts' experience, about 60% of failures in industrial plants related to fluid systems can be predicted and avoided with properly installed level control systems. We offer comprehensive solutions - from basic F&F liquid level control relays to advanced WILO level sensors for the most demanding applications.

How level sensors revolutionize industrial safety
Safety in industrial plants is a priority that does not tolerate compromises. In our assortment, you will find liquid level control relays designed specifically to detect the presence of electrically conductive fluids. These devices act as the first line of defense against catastrophic failures.
Preventing leaks and environmental damage
Modern level control systems represent environmental responsibility in practice. Our sensors immediately detect abnormal filling states in tanks, allowing for a rapid 
response from service teams. In chemical and petrochemical installations, where the risk of environmental contamination is particularly high, these devices are a key element of safety systems.
Protecting expensive equipment from damage
Protecting pumps from dry running is one of the most important aspects of operating pumping systems. From our experience, the cost of replacing a damaged pump can be up to 50 times higher than the investment in a professional level control system. The solutions we recommend automatically shut down devices when the liquid level falls below a safe minimum.
Which sensor technologies work best in industry
The diversity of industrial applications requires varied technological solutions. Our offer includes all major types of sensors, each with unique advantages tailored to specific applications.
Hydrostatic sensors - precision in all conditions
Hydrostatic sensors use hydrostatic pressure measurement to determine liquid levels. They are particularly valued in industry for their high accuracy and resistance to changing environmental conditions. They are ideal for monitoring levels in tanks with aggressive chemicals, where other technologies may fail.
Float systems - reliability proven over the years
Float level sensors are a solution with proven reliability that we have been using in installations for decades. Their mechanical construction based on the principles of physics makes them less susceptible to electromagnetic interference and operate reliably even in harsh industrial conditions.
| Technology | Main advantages | Typical applications | Measurement range |
|---|---|---|---|
| Hydrostatic | High precision, resistance to conditions | Chemical tanks, refineries | 0.1 - 25 m |
| Float | Simplicity, mechanical reliability | Wastewater treatment plants, pumping stations | 0.2 - 15 m |
| Ultrasonic | Non-contact measurement, easy installation | Open tanks, wells | 0.3 - 50 m |
| Capacitive | Compactness, accuracy | Small tanks, OEM applications | 0.05 - 3 m |
Specific economic benefits from implementing control systems
Investing in professional level control systems is a decision with measurable economic benefits. Our client case analyses show average savings of 15-30% in operational costs in the first year of use.
Optimization of raw material and media consumption
Precise level monitoring enables accurate dosing of raw materials and technological media. In the chemical or food industry, where product quality depends on precise ingredient proportions, every percentage improvement in accuracy directly translates into increased profitability.
Reduction of service and failure costs
- Predictive maintenance - early detection of anomalies allows for service planning
- Minimization of downtime - automatic alarms enable quick operator response
- Extended equipment lifespan - proper working conditions mean fewer mechanical failures
- Savings on insurance - monitoring systems often lower premiums
Practical implementation in various industrial sectors
Each industrial sector has its specific requirements for monitoring liquid levels. At Onninen, we tailor solutions to specific needs, leveraging our experience across various sectors.
Chemical and petrochemical industry
In chemical plants, it is crucial to use sensors resistant to aggressive chemical environments. We recommend solutions made of acid-resistant steel or specialized materials that ensure long-lasting reliability even in contact with acids, bases, and organic solvents. Our industrial solutions include a full range of devices certified for operation in explosion hazard zones.
Food and pharmaceutical industry
The food and pharmaceutical industries require the highest hygiene standards. The sensors we offer meet strict sanitary standards, are easy to clean, and do not affect product quality. Surfaces in contact with media are made of materials approved for food contact.
Energy and power plants
In power plants, monitoring the levels of cooling liquids is a matter of national energy security. Our systems provide continuous monitoring with measurement redundancy, eliminating the risk of failure due to incorrect readings from a single sensor. We offer solutions adapted for operation at high temperatures - up to 100°C.
Integration with industrial automation systems
Modern level sensors are not just measuring devices, but integral elements of industrial automation systems. In our offer, you will find solutions compatible with the most popular 
communication protocols and control systems.
Communication and remote management
Modern industrial plants require remote access to measurement data. The systems we offer enable data transmission over industrial networks, the internet, and wireless systems. Operators can monitor level states from anywhere in the world, which is particularly useful in managing multi-branch enterprises.
Predictive algorithms and artificial intelligence
The latest solutions in our assortment utilize advanced analytical algorithms. These systems not only measure the current level but also predict trends in changes, optimize dosing processes, and automatically adjust operating parameters to changing conditions. This is the future of industry 4.0, which can already be implemented in your plant today.
