Visual Level Indicators (VLI) Standard Series

Product catalog summary
Overview of Visual Level Indicators (VLI) Standard Series
Specifications: The document details the specifications for various VLI series, including Standard Series 6, 28, and 50. Each series has distinct pressure and temperature ratings, with Series 6 operating at a maximum of 6 bar at 20°C and a temperature range of -80°C to +150°C. Series 28 can handle up to 28 bar and temperatures from -100°C to +400°C, while Series 50 allows for pressures up to 50 bar at 20°C and temperatures from -80°C to +400°C.
Design and Materials: All series are constructed with 316/316L stainless steel for the float chamber. Screws and nuts conform to A2-70 standards, and float materials include 316L and titanium alloy. Gaskets are made from Aramid/NBR, PTFE, or graphite, depending on temperature requirements.
Process Connections: Standard connection threads are female G1/2" (ISO 7-1 / ISO 228-1), with options for EN and ANSI flanges. The document specifies dimensions and materials for these connections.
Operating Conditions: The VLIs comply with PED 2014/68/EU standards. Series 28 operates with fluid densities from ≥ 0.54g/cm³ to ≤ 1.5g/cm³ and viscosities up to 600cSt. The document stresses adherence to pressure-temperature ratings to avoid limitations.
Accessories and Installation: Available accessories include fixation brackets, magnetic switches, and transmitters. Installation instructions are referenced by specific drawing numbers.
Float Selection and Diagrams: Float selection diagrams indicate permissible pressures and densities for different series. Correct float type selection is crucial, with additional charges for certain density ranges.
Notes and Certifications: The document includes notes on special executions, test pressures, and certifications like EN10204:2004-3.1 for materials used in the float chamber. It emphasizes that all dimensions are valid only for standard executions.
Graphical Data: A pressure-temperature diagram for VLI Standard 28 shows the operating range and limitations based on fluid temperature and pressure.
