The invention if the damping time constant (Dτ) is changed to Dτ = 0, and an object thereof is to automatically change the sampling period (Ts) from 100 ms to 50 ms. In addition, the automatic change sampling time (ts) from 60 ms to 30 ms. Accordingly, the processing device 3, the damping time constant (Dτ) is Dτ = If the change to zero, the differential pressure sensor (1) an electric signal corresponding to the pressure difference of the fluid is detected, the sampling period Ts = sampling time for each 50 ms sampling for ts = 30 ms, and the sampled electric signal subjected to various processing operations, such as linear operation, square root operation to obtain the differential pressure measured value (ΔP). In this calculation process, the processing device 3 does not perform a damping operation.
