Continuous level measurement

Unlike point level sensors, which can only detect a media level at a predefined point, level sensors detect the exact level of a medium in real time. The user is thus informed at all times about the current, percentage content of the container, which optimizes inventory management and reduces costs.

There are different technologies for continuous level measurement such as capacitive and radar sensors as well as electromechanical plumb bob systems, all have advantages but also disadvantages depending on the application. For the selection, numerous process conditions have to be considered, which have to be mastered for the sensor technology. In addition, the requirements for bulk solids sensors differ from those for liquid sensors. For this reason, UWT offers a broad portfolio of different technologies. This allows us to individually address their requirements to always provide them with the best possible solution.

Typical challenges:

• Media type (e.g. bulk, powder, liquid, paste, etc.)
• Media properties (e.g. bulk density, conductivity, viscosity, etc.)
• Input conditions (e.g. tank material, tank geometry, installation position, installations within the tank, etc.)
• Process conditions (e.g. pressure, temperature, ambient conditions, explosion protection, hygiene requirements, etc.)

FAQs

What is the difference between limit level and fill level?

In contrast to point level sensors, which only provide information on whether a certain level value has been exceeded or fallen below, continuous level sensors provide the current value of the level in the tank, i.e. from 0 % to 100 %.

How do you measure the fill level??

Level measurement is used to determine the fill level of media in industrial containers, such as process and storage tanks, silos or open channels. For this purpose, measured values are transferred into electronic signals. The output signal is integrated into the control loop of the process control system..

What conditions influence the choice of level measurement technology??

Liquid or solid, temperature, continuous measurement or limit level measurement, noise, dielectric constant, pressure, chemicals, material resistance, tank size, bulk material, density, agitators, measuring accuracy, price, shocks, vibration, container shape, calibration, response time, programming, size of the device, build-up..

How can fill levels be visualised?

Fill levels can be displayed in various ways. From the simplest indicator lights, digital display devices or touch panels to web server-based solutions. It is then possible to display the fill levels on PCs, laptops, tablets and smartphones. Locations are networked with each other and interfaces to ERP systems are created. Old and new systems can be flexibly connected and analysed.
