The combination of VEGAPASS 81 with VEGAFLEX enables a continuous level measurement outside the vessel. The bypass consists of a standpipe which is mounted as communicating vessel laterally to the vessel via two process fittings. This kind of mounting ensures that the level in the standpipe and the vessel are the same. Technical specifications Measuring range - Distance 4 m Process temperature -196 ... 450 °C Process pressure 0 ... 205 bar Application range VEGAPASS, is a bypass chamber mounted on the outside of a liquid tank, which is designed to hold a level, point level or interface measuring instrument. Due to the large selection of materials, VEGAPASS instruments can also be used for aggressive liquids. Measuring principle VEGAPASS consists of an externally mounted chamber or standpipe with lateral process fittings into the tank, which has the same level as inside the tank. By adding a suitable instrument into the chamber, an electronic measurement of level, point level or interface can be carried out. VEGAPASS and the additional measuring instrument form a measuring system, which is engineered and delivered pre-assembled on request. Advantages VEGAPASS can be completely isolated from the tank by means of valves built into the process fittings.
