The Foxboro Levelstar 244LD series consists of level meters with a displacement (buoyancy) measurement principle. This principle is based on the law of Archimedes that states that the upward force is equal to the weight of the displaced liquid. This makes the LevelStar also suitable for measuring level differences between two different liquids (interface). The LevelStar series immediately measures the upward force without moving parts and is therefore extremely robust and durable. The 244LVP is available with different connections and materials. In addition to an analog output, the LevelStar also communicates digitally with Hart, Profibus or Foundation Fieldbus. The 244LD is suitable for process temperatures up to 500 ° C, because the electronics are not directly above the displacer, but on the side. There are intrinsically safe and explosion proof versions according to ATEX, FM, CSA, Nepsi and GOST-R, among others.
