In the food industry, precise measurement of tank fill levels is critical to maintaining product quality, production efficiency and process safety. Accurate fill level monitoring helps optimize raw material consumption, minimize losses and avoid overfilling or underfilling tanks, which could lead to contamination or damage to equipment. In this article, we will provide an overview of modern technologies used in measuring fill levels in food tanks. We will discuss different types of measuring sensors, such as capacitive, ultrasonic, radar, hydrostatic, vibration and pressure transducers, and compare their advantages, disadvantages and applications.

Thanks to modern technologies, it is possible to achieve high precision, which translates into better control over raw materials and products. Here are three main aspects that highlight the importance of precise fill level measurement in tanks:
Quality control: Precise level measurement in storage tanks allows for monitoring the quantity of raw materials and products, which helps maintain consistent quality and prevents contamination.
Production efficiency: Optimizing production processes with accurate fill level measurement enables better management of raw materials, minimizing waste and increasing operational efficiency.
Safety: Fill level measurement prevents tank overflows and protects personnel from the dangers of handling overfilled or underfilled tanks, improving working conditions and plant safety.

The food industry uses various technologies to accurately monitor the level of raw materials and products. Let's discuss some of them below
Capacitive level sensors work by measuring changes in electrical capacitance between the probe and the tank wall. They are used for both liquids and bulk materials. Their versatility makes them ideal for a variety of industrial applications, such as overfill and dry-run protection, as well as media detection in separation processes. An example of such a device is the JUMO ZELOS C01 LS capacitive limit level indicator, which identifies the level of liquids and solids, can be used in pressurized tanks, and is resistant to high pressure and temperature.

Hydrostatic probes measure the pressure exerted by a liquid on a sensor located at the bottom of a tank, allowing the level of the liquid to be determined accurately. They are particularly useful in tanks with liquids of constant density, such as drinking water. They are economical and easy to install, making them a popular choice in the food industry. The JUMO MAERA S26 is an example of a PZH-approved hydrostatic probe, ideal for contact with drinking water, that provides precise measurements in applications requiring compliance with hygienic standards.

Pressure transmitters mounted on the bottom of the tank are used to measure the pressure exerted by the liquid, allowing the precise determination of the fill level. These devices are reliable, hygienic and can operate over a wide temperature range, making them ideal for applications in the food and pharmaceutical industries. The JUMO DELOS SI Precision Pressure Transmitter with Display is an excellent example of such a device, which offers an EHEDG-compliant hygienic pressure sensor and a configurable measurement range, making it ideal for CIP and SIP processes.
Each of these technologies offers unique advantages and is applicable in a variety of scenarios, helping to ensure accurate and reliable fill level measurement in the food industry.

What is the future of level measurement technology in the food industry? Integration of measurement technology with IoT (Internet of Things) systems is one of the most important developments. Sensors connected to the network enable remote monitoring of filling levels in real time, allowing for better control and optimization of production processes. With IoT, it is also possible to detect problems early and react quickly to changing conditions, minimizing the risk of failures and losses. An example of such a device is the JUMO ZELOS C01 LS Capacitive Boundary Level Sensor, which not only identifies liquid and solid levels, but also has IoT functionality for real-time monitoring and integration with advanced production management systems.
