Measurement container for tar and similar fluids - uses displacement body for vol. variation whilst eliminating sealing problems by placing body adjustment above highest fluid level

摘要

The measurement container has a variable vol. and is for tar and similar fluids overcomes the problem of leakage of fluid, esp. of chemical dissolution of rubber and plastic seals and thermal damage to chemically stable seal material. The volume is varied by immersion of a displacement body (2) into the fluid. The body position adjustment device (5) is placed above the highest fluid level (3), thus allowing the container to be sealed with material not subjected to a thermally or chemically hostile environment.
