Title: Dynamic pressure measuring apparatus in piping
Inventor: NAKAZAWA YOSHIO
IPC: G01L7/00
Filed: 1996-11-01
Abstract: PROBLEM TO BE SOLVED: To eliminate the need of providing a port for measuring dynamic pressure in a piping, by fixing a strain gauge on the outer surface of the piping. SOLUTION: A strain occurring in a piping 3 due to dynamic pressure of a fluid in the piping 3 is measured by a strain gauge 1 without providing any port, and the dynamic pressure of fluid in the piping 3 can be measured with a data processing PC(personal computer) 8. A measured strain is corrected by a data processing PC 8 based on the temperature of fluid detected through a temperature sensor 6 according to a predetermined relation between the temperature and the strain thus measuring dynamic pressure of fluid in the piping 3 accurately. The piping 3 for measuring dynamic pressure requires no dedicated port.  Furthermore, static pressure can also be measured by measuring strain through the strain gauge 1 and since the static pressure is measured at same position as the dynamic pressure, a data related to strain can be obtained as a calibration value by imparting an actual load pressure to the piping 3.
