Really the volumetric flow of measurement gas flow measures instrument, with precision height, good reliability, lightweight, long lifespan, running noises
Low feature, suitable for noncorrosive gases such as measurement natural gas, town gas, propane, nitrogen, industrial inertia gases, extensively should
Combustion gas business for industries such as food and drink, hotels is settled accounts, transmission and distribution network gas metering, and gas pressure regulating station metering is industrial and civilian
The gas meterings such as boiler.The operation principle of gas Roots flow meter is as follows：Loaded on a pair of conjugate rotors in measuring room in circulation
(P enters the gateway pressure difference of gas>P goes out) effect under, two rotors alternately bears rotating torque.Rotor is often rotated one week, then is exported
The gas of four times of measuring room dischargeable capacitys, the revolution of rotor is delivered to integrating by magnetic seal hitch bar and reducing gear
Indication counter, so that the cumulative volume amount of display output gas.
Roots's gas flowmeter can be accurately measured gas flow, but it still suffers from the place of some shortcomings：Such as
For the special occasions that those are inconvenient to read data, flowmeter is used and is just restricted；Due to flowmeter in transit
Be easy in installation process in granule foreign immersion table body, be difficult to discover.Flowmeter card table, shadow are caused in the trial operation stage
Ring and just commonly use gas, gas user and producer are all adversely affected.
The content of the invention
The purpose of this utility model be for technological deficiency present in prior art, and one kind is provided can remote transmission number
According to, can prevent impurity enter Roots's gas flowmeter body in Roots's gas flowmeter.
To realize that the technical scheme that the purpose of this utility model is used is：A kind of intelligent Roots's gas flowmeter, including
Measuring room, housing, intelligent digital flow integrator, it is characterised in that described measuring room one end is equipped with air inlet, the measuring room
Opposite side is equipped with provided with a pair of conjugate rotors that housing is divided into inlet chamber and outlet chamber in gas outlet, the housing, described common
Yoke rotor includes two tangent waist wheels and is arranged at two roots rotor axles of waist wheel central axis, the armature spindle and measuring room
Two side bodies are connected, and described intelligent digital flow integrator is arranged on the upper end of the housing.
Described intelligent digital flow integrator include pipe pressure sensor, pipeline pressure data-interface, computing chip,
Barometric pressure sensor, voltage stabilizing chip and wireless communication module.Described wireless communication module can be received through handling computing
Pressure signal, flow signal.
It is respectively arranged with the air inlet of described flowmeter and gas outlet in the installation groove of annular, the installation groove
Screen pack is installed, the screen pack is made up of two layers of silk screen, internal layer is the low silk screen of mesh number, plays a part of support, outer layer
For the high silk screen of mesh number, play a part of impurity screening.
Compared with prior art, the beneficial effects of the utility model are：Intelligent Roots's gas flowmeter of the present utility model
Filter assemblies are installed at air inlet and gas outlet, it is to avoid Roots's gas flowmeter has impurity entrance in transport and installation process
Cause card table failure in table body, improve the reliability used；The utility model intelligence Roots gas flowmeter is equipped with intelligent number
Word flow integrator, not only measures accurate, and can realize and be wirelessly transferred, and is conveniently used for the occasion for being difficult to read data.
Brief description of the drawings
Fig. 1 show the schematic diagram of the intelligent Roots's gas flowmeter of the utility model.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.Obviously, described reality
Apply a part of embodiment that example is the present invention, rather than whole embodiments.Based on the embodiment in the present invention, this area is common

Scope.
The schematic diagram of the utility model intelligence Roots's gas flowmeter is as shown in figure 1, including measuring room 1, the measuring room
One end is equipped with air inlet 2, and the measuring room opposite side is equipped with gas outlet 3, be provided with the housing by housing be divided into inlet chamber and
A pair of conjugate rotors of outlet chamber, the conjugate rotors include two tangent waist wheels and are arranged at two of waist wheel central axis
Armature spindle 4, the armature spindle is connected with two side bodies of measuring room, and the upper end of described flowmeter shell is equipped with intelligent digital
Flow integrator 5.
Described intelligent digital flow integrator include pipe pressure sensor, pipeline pressure data-interface, computing chip,
Barometric pressure sensor, voltage stabilizing chip and wireless communication module.Described wireless communication module can be received through handling computing
Pressure signal, flow signal.
It is respectively arranged with the installation groove 6 of annular, the installation groove and pacifies at the air inlet of flowmeter and gas outlet
Equipped with screen pack 7, the screen pack is made up of two layers of silk screen, and internal layer is the low silk screen of mesh number, plays a part of support, outer layer is
The high silk screen of mesh number, plays a part of impurity screening.
Flowmeter is from dispatching from the factory, transportation, until in-site installation is all protected by filter assemblies, prevent impurity from entering flowmeter
In vivo, fault rate caused by card table is significantly reduced.
Gas enters measuring room through air inlet, is pressed loaded on a pair of conjugate rotors in measuring room in the gateway of circulated gases
(P enters difference>P goes out) under effect, two rotors alternately bear rotating torque, and rotor is often rotated one week, then four times of measuring rooms of output are effective
The gas of volume, the revolution of rotor is delivered to integrating indication counter by magnetic seal hitch bar and reducing gear, so that
The cumulative volume amount of display output gas.
