PRESSURE MEASURING INSTRUMENT

摘要

PROBLEM TO BE SOLVED: To measure the pressure of fluid at an arbitrary piping place to be measured while lowering cost and simplifying constitution. SOLUTION: This pressure measuring instrument has a static pressure detection part 7 and a flow rate measuring part 8 united together. According to data regarding the static pressure P1 of gas from the static pressure detection part 7 and the flow rate Q from the flow rate arithmetic part 10, a total pressure arithmetic part 10 takes a pressure drop into account to calculate the gas supply pressure (total pressure) P0 at an arbitrary place of a pipe 1. The calculated total pressure P0 is stored in a storage means in the total pressure arithmetic part 10.
