Over time, level measurement in solids has become increasingly important. This case study discusses how with Endress+Hauser´s RIA15, the FMR56 can continually monitor levels in seven circular compartment silos at one of the building-material manufacturers in Karlsruhe, Germany.

Based out of Karlsruhe, Germany, a building material manufacturer has been continually investing in the development and improvement of products in cement, concrete and other building materials. This investment enables the company to offer customized solutions for the industry.

Problem

The major challenge for this company was measuring level in narrow compartments with different grain sizes (0 to 16 mm). Moreover, it also wanted measurement during a running process with high filling noise levels.

Huge plants have level measurement devices installed on top, where the information can be read directly in the field. However, this makes it difficult to read the measurement value in front of the tank.

Generally, the displays are placed at the top of the tank and there is no display on the ground. Here, the RIA15 loop indicator helps to easily monitor the tank status. In addition, it has the information at the exact place you need it.

Monitoring tanks easily

Endress+Hauser realized these requirements with the comprehensive integration of the Micropilot FMR56. Here, with the help of the RIA15 remote display,  monitoring the tank status becomes easier and effective.

With the Micropilot FMR56, the uniformity is demonstrated in documentation, operation, diagnosis, Ex-instruments, and spare parts as well as many other details.

This leads to a cost reduction in planning, procurement, and operation. It’s also the first uniform two-wire instrument concept for flow and level to increase safety and reduce costs.

How is the problem addressed?

With a product extension by a DN 100 antenna, the economically efficient Micropilot FMR56 basic instrument could handle this measuring task. Here, the DN 100 antenna ensures improved focus of the radar waves (with an 8° emitting angle) as well as very high signal dynamics.

The design of the new FMR56 radar generation provides an additional signal yield of 10 dB. With these properties, Micropilot can measure safely in multiple circular compartment silos during filling with high filling noise levels without any problems.

Also, the new data management of the FMR56 allows the duplication of instrument parameters via the display. This reduces the time period to commission the seven instruments considerably.

Solution components

The FMR56 ensures safe level values even during filling and high filling noises. It has a short commissioning period due to display duplication function. It also has a maintenance-free operation.

The solution components include 7 Micropilot FMR56 level instruments with DN 100 antennas, 7 RMA42 transmitter power supply units and
7 RIA15 process displays on a separate plate and commissioning by Endress+Hauser. 

Conclusion

In the process industry, automation engineering requirements are constantly increasing. The complexity is continually increasing for users due to numerous measuring tasks and the instruments of different manufacturers available in this respect. At the same time, requirements concerning operational safety and availability of facilities are increasing too.
