Visual Level Indicators (VLI) Petro
Visual Level Indicators (VLI) Petro
The document outlines the design specifications for a system operating within a temperature range of -80°C to 400°C, with options for lower temperatures down to -162°C. The maximum operating pressure is 66.2 bar(g) at 20°C, with design pressure to be specified. The pressure design adheres to ANSI/ASME B31.3 standards for Chemical Plant & Petroleum Refinery Piping. Key materials include a 316/316L double certified float chamber, Ti-alloy float, and A-193 B8 Cl. 2 / A194 Grade 8 stud bolts and nuts. Spiral wound gaskets are used, with PTFE or Graphite options based on temperature requirements.
Standard connections feature butt weld ends and flanged connections (DN.../PN100 or class600). NPT female thread sizes are available, with specifics advised upon order. The maximum connecting distance for a one-piece design is 6000mm. Accessories include magnetic switches and transmitters, with specifications dependent on the float type.
Test pressure is specified according to WEKA's "Pressure- and Temperature Information". Material compliance is verified according to EN10204-3.1B for the float chamber. Heavy fixation for indication rail is specified for conditions involving vibrations and shock.
All dimensions are provided in millimeters and are available only in standard execution. Modifications to the standard design are reserved, with special executions noted as required.
