PURPOSE:To make it possible to measure easily average pressure by communicating and connecting to a vessel ends of a plurality of pressure tubes that have the other ends opened into the pressurized liquid and measuring pressure in the vessel with liquid filled in the vessel and the communicating and connection sections. CONSTITUTION:Pressure supply tubes 1 and 2 are preferably for convenience made of vinyl or other flexible materials, and their ends are opened into liquid pressure of which is to be measured. The pressure supply tubes 1 and 2 communicate respectively through communicating and connecting tube 3 and 4 with a vessel 5. Liquid is filled in the vessel 5 and the lower ends of the communicating and connecting tubes 3 and 4, and a pressure gauge is installed at the bottom of the vessel 5. Average pressure of the liquid flows into which the pressure supply tubes are inserted can be measured by making equal the cross sections of the communicating and connecting tubes 3 and 4. |
