サが用いられる。 As for the load sensors 5 and 6, since it is desirable that the load direction of the sensors is always perpendicular to the horizontal bar 3, sensors with small displacement such as strain gauges are used.
流体が流れる管体９にはノズル（枝管）１０が
設けられており、このノズル１０より垂直バー２

となる。ここで、
ρ：流体の密度
Ｖ：流体の流速
Ｋ：比例定数

Fp＝Ｐ・Ｓ ……(2)
である。 Further, since the flexible tube 12 has almost no restraining force in the vertical direction, a force F p due to the fluid pressure P acts on the disk portion 11 of the T-shaped arm 1, assuming that the fluid pressure is P.

となる。ここでl1，l2は、それぞれ片側の水平バ
ー３の長さ及び垂直バー２の長さである。 From the above, if the forces acting on the two load sensors 5 and 6 are F A and F B , then from the balance of force and moment F A + F B = F p = P S... (3) (F B - F A ) l 1 = F d・l 2 ...(4). Here, l 1 and l 2 are the length of the horizontal bar 3 and the length of the vertical bar 2 on one side, respectively.
(1)〜(4)式を整理すると Ｐ＝FA＋FB／Ｓ ……(5) V2＝l1／l2・Ｋ・ρ（FB−FA ……(6) となる。 Rearranging equations (1) to (4), we get P=F A +F B /S...(5) V2 = l1 / l2・K・ρ(F B −F A ...(6).

is determined by the pressure P, and since S, l 1 and l 2 are constant, F A and F B acting on the two load sensors 5 and 6
By measuring , the pressure P and flow velocity V can be obtained from equations (5) and (6), and the flow rate can be determined from the flow velocity V and the inner diameter of the tube body 9. Note that K·ρ is determined by the measured pressure P.
このように、上記流量・圧力測定装置によれば
従来、流量計と圧力計を別々に設置して行なつて

つぎに、第４図を参照して第２発明に係る流
