Compact and Reliable Level Detection

The SITRANS LVL100 is a highly reliable vibrating point level switch designed for industrial applications involving liquids and slurries. Its compact design, with an insertion length of just 40 mm, allows for easy integration into tight spaces, such as small pipes and machinery.

The LVL100 is virtually unaffected by the chemical and physical properties of the liquids it measures, making it suitable for even the most challenging conditions, including turbulence, air bubbles, foam buildup, and external vibration.

The piezoelectrically activated tuning fork ensures consistent and accurate detection by registering changes in vibration frequency when covered by a medium.

Proper Installation for Reliable Performance

When installing the SITRANS LVL100, ensure the instrument is mounted in accordance with the permissible process conditions, which include pressure, temperature, chemical properties, and abrasion levels. The tuning fork must be positioned at the desired switching point, with consideration of the medium’s density as this may shift the switching point. Use appropriate sealing materials for vessels under pressure, and ensure that the process fitting is correctly sealed. Special care should be taken to protect the instrument from moisture, especially in outdoor installations or areas with high humidity. Do not handle the device by the tuning fork, as this could lead to damage.

Mounting Guidelines for Effective Operation

SITRANS LVL100 can be mounted in any orientation, but special attention should be paid to horizontal installations in adhesive or viscous media. In these cases, the surfaces of the tuning fork should be positioned vertically to minimize buildup. For threaded versions, the instrument's position is defined by the thread, ensuring that each device is properly aligned. In high-flow areas, such as pipelines, the sensor should be mounted so that the tuning fork is parallel to the product flow to reduce resistance and prevent false readings. Avoid mounting near agitators or filling streams to minimize disturbances that could lead to inaccurate measurements.

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.
