High Delta P Valve Masoneilan Oil Gas Level Control Valve 12400 12420-51 Digital Level Transmitter Controller for Storage Tanks

Product Overview The 12400 series uses a torque-tube displacer with smart electronics to measure level or interface in process vessels. It is particularly common in refineries for crude/vacuum column boots and separators because it handles high pressure and temperature, and the design keeps the sensitive parts away from the process fluid.

• Classic torque-tube displacer principle
• HART smart electronics with local display
• Push-button calibration and setup
• Multiple displacer options for different services
• Wide pressure and temperature capability
• Suitable for level, interface and density

• Measurement Range: 356 mm to 3048 mm (14" to 120")
• Process Pressure: Up to ANSI Class 2500 / PN 400
• Process Temperature: -196 °C to +400 °C
• Accuracy: ±0.5% of span typical
• Output: 4–20 mA HART
• Materials: Carbon steel, 316L stainless steel, Hastelloy C, Monel
