Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Referring to Fig. 1, the utility model provides a kind of technical scheme：A kind of orifice flowmeter, including flowmeter bodies 1,
The left end of the flowmeter bodies 1 is provided with air inlet 2, and the bottom of flowmeter bodies 1 is provided with installation fixing hole 3, described
Flowmeter bodies 1 are provided with straight length 4 and pressure vessel 6, and straight length 4 is arranged on the both ends of pressure vessel 6, the straight length 4
Top is provided with temperature survey mouth 10, and temperature sensor 11 is provided with temperature survey mouth 10, the inner chamber peace of the pressure vessel 6
Pressure tappings 8 pressure tappings 9 and orifice plate after are respectively arranged with before orifice plate equipped with orifice plate 5, and at left and right sides of the top of pressure vessel 6, it is described
The right-hand member of flowmeter bodies 1 is provided with gas outlet 7.
Wherein, the installation fixing hole 3 is symmetrical not less than two groups installed in the bottom of flowmeter bodies 1；Institute
