LP Steam Preheating Skids - Monitor using a Magnetic Level Indicator under vacuum

Customer: Gas Preheater Skid Manufacturer

Duty: Steam under vacuum conditions

Liquid: Water/Steam, Pressure: Full vacuum to 1.2 bar g, Temperature: -10 to 105 deg C

Application: The client manufactures preheat solutions for gas distribution networks, utilising low pressure steam to provide heating at temperatures down to 39 deg C. They had previously used glass level gauges, but experienced difficulties in providing adequate sealing through the threaded connections and gasketing around the glass.

Solution: Magnetic level gauges provide a fully welded solution. With just one flange connection (for float removal), potential leak paths are greatly reduced and it was much easier for the client to maintain under vacuum conditions.
