Robust Applications of the SITRANS LVL200

The SITRANS LVL200 is engineered for a wide range of applications across process technology, particularly in liquid and slurry environments. It is highly effective for level measurement, overfill protection, and dry-run monitoring, catering to various industry needs.

The ability to function in harsh conditions—such as high temperatures and pressures—makes it suitable for diverse applications, from food and beverage to chemical processing. With its proven vibrating fork technology, the LVL200 provides accurate level detection and minimizes the risk of operational failures.

Its adaptable design not only supports straightforward installation but also accommodates the specific requirements of different industries, further underscoring its utility as a reliable solution for level monitoring.

LVL200 Installation Siemens 1024 16X9

Proper Installation Guidelines for the SITRANS LVL200

When installing the SITRANS LVL200, it is crucial to ensure that all components in direct contact with the process—such as the sensor element, process seal, and fitting—are compatible with the existing process conditions, including pressure, temperature, and the chemical properties of the medium.

The instrument can be mounted in any position, but the tuning fork must align with the desired switching point. The lateral markings on the tuning fork help determine this point, particularly when installed vertically. It’s essential to adjust the density switch based on the medium's density, especially when working with foams, as they can lead to erroneous switch activations.

To enhance moisture protection, install the connection cable so that it leads downwards at the cable entry.

Detailed Mounting Instructions for Optimal Performance

The SITRANS LVL200 features a defined thread position, ensuring consistent fork positioning upon installation. Prior to installation, remove the supplied seal from the thread, as it is unnecessary when using a welded socket with an O-ring.

For horizontal installations in adhesive or viscous products, the tuning fork should be oriented vertically to minimize buildup. The positioning of the welded socket is critical; it should be aligned with the flow direction for pipelines, and the notch marking should face upward. It is also vital to install the instrument away from disturbances such as filling openings or agitators to prevent false measurement signals.

Care should be taken with instruments that have enamel coatings, as they are sensitive to shocks and must be handled delicately during installation.

Choosing the Right SITRANS LVL Model for Your Application

When selecting the right SITRANS LVL model, it’s important to match the features of each device to the specific application requirements. Siemens offers three distinct models, each designed for varying levels of complexity and environmental conditions, providing customers with versatile options for liquid and slurry level detection.

The SITRANS LVL100 is perfect for confined spaces, offering a very compact design with an insertion length starting at just 40 mm. It is ideal for dry-run protection and ensures reliable fault monitoring for corrosion, loss of vibration, and line break in tight spaces. This model is particularly suited for standard liquid and slurry detection where space is limited, such as small pipes and vessels.

The SITRANS LVL200, on the other hand, is built for more demanding conditions, such as detecting liquified gases with densities as low as 0.5 g/cm³. It operates efficiently in environments with large temperature variations (-40°C to 30°C) and includes enhanced safety features like fail-safe operation and SIL2 certification. The LVL200 is also designed to monitor corrosion and mechanical wear, making it ideal for harsh industrial applications with extreme pressures and temperatures.

Each model addresses different needs, allowing customers to select the best solution for their specific liquid or slurry level detection challenges.
