Technical Reference

When the dust settles (and the echo is regained) the reported level advances toward the actual level. When the reported level reaches 25.55 m (5% of Span less than the high high alarm trip point), the high high alarm goes off, restarting the infeed and filling the vessel to 27.00 m.

Material Volume

To perform a volume conversion for the preceding example, we'll assume:

•the vessel is cylindrically shaped with a flat bottom.

•the vessel volume for Empty to 29.01 m (Span) is 1457 m3.

P050

Tank Shape

Enter "1" for vertical cylinder with flat bottom.

P051

Max Volume

Enter "1457" for 1457 m3.

Now in the RUN mode the Reading represents material volume in m3.

Example 2 - Space Measurement

This mode of operation is commonly used when remaining vessel capacity is of more importance to the installation than the actual material level.

Space

For this example we'll assume the following:

•the vessel is a 3 ft diameter by 15 ft long cylinder (including the parabolic ends of 1.5 ft each).

•the maximum vessel filling rate is 1 ft per minute (slower at mid level).

•a mA output scaled from 4 mA at Full to 20 mA at Empty is required for PLC operation.

•in the event of a measurement difficulty, failsafe operation is to be activated in 6 seconds.

•if the difficulty doesn't subside, the mA output must immediately assume 22.00 mA.

•an XCT-8 transducer is mounted in a standpipe so that the face is 18 in. above the vessel top.

•a TS-3 temperature sensor is mounted in the vessel to monitor liquid temperature.

LU01 specifications

The Siemens LU01 is a state-of-the-art train control and signaling system designed to enhance the safety and efficiency of rail networks. This sophisticated system leverages advanced technologies and innovative features to ensure seamless train operations, lower maintenance costs, and improved overall performance.

One of the main features of the Siemens LU01 is its implementation of the European Train Control System (ETCS). ETCS is a vital component in modernizing rail infrastructure across Europe, aiming to standardize various train control systems for enhanced interoperability among different national networks. The LU01 facilitates the integration of ETCS Level 1 and Level 2, allowing for both trackside equipment and onboard systems to work in harmony to manage train movements effectively.

Additionally, the LU01 employs a decentralized architecture that enhances system reliability and minimizes downtime. This design means that it can operate even in the case of individual component failures, ensuring that train operations remain uninterrupted. Furthermore, the LU01 utilizes advanced diagnostic tools and predictive maintenance technologies to monitor system performance continuously. This proactive approach allows for early identification of potential issues and timely maintenance, which contributes to reducing operational costs.

Another critical characteristic of the Siemens LU01 is its capability for real-time data transmission. The system integrates wireless communication technologies, enabling constant connectivity between trains and control centers. This feature allows for real-time updates on train positions, speeds, and other critical operational data, thereby enhancing situational awareness for train operators and maintaining optimal schedules.

Moreover, the LU01 is designed to be compatible with existing rail infrastructure, ensuring a smooth transition for railway operators looking to upgrade their signaling systems without extensive overhauls. This adaptability makes it an appealing choice for both new projects and retrofitting existing rail networks.

In summary, the Siemens LU01 stands out for its cutting-edge features, including support for ETCS, decentralized architecture, real-time data communication, and compatibility with legacy systems. With these technologies and characteristics, the LU01 significantly contributes to the safety, efficiency, and sustainability of modern rail transport systems, making it a pivotal solution in the evolution of railway operations.
