Abstract
The utility model relates to an anti-corrosive remote transmitting glass rotor flowmeter which comprises a tapered glass tube, wherein a rotor is arranged in the tapered glass tube, and graduations are arranged on the tube wall. The utility model is characterized in that magnetic materials are filled in the rotor, and a row of dry-reed pipes which correspond to the flow rate of fluid are fixed to the outer side of the tapered glass tube. The flow rate is indicated by the height of the rotor when the fluid passes through, and the dry-reed pipes corresponding to the flow rate are attracted by the magnetic materials; thus, the dry-reed pipes are conducted to output corresponding currents through an electronic circuit. Thereby, the currents can be remotely sent to a digital display meter to display the flow rate and can be used as automatic control signals. The utility model has the characteristics of convenience, simplicity, direct viewing, etc. As long as an operator is in an operating room, the operator can clearly see the flow rate indication. The cost of the utility model is only a quarter of that of an original remote transmitting flowmeter. Therefore, the production cost and the use cost of a user are saved.
Description
Technical field
The utility model belongs to a kind of instrument, particularly to the improvement of glass rotameter structure.
Background technology
Existing a kind of glass rotameter, its structure be, has rotor in the tapered glass tube, has scale on the glass tube.During work, rotor raises with the increase of liquid or gas flow, observe its numerical value, will arrive field observation.The flowmeter of this structure, incompatibility teletransmission and automatic control bring certain difficulty and inconvenience to use.As solving the purpose of teletransmission and automatic control, must adopt cost to realize than the metallic rotator flowmeter that it exceeds 5～10 times.
Summary of the invention
The utility model provides a kind of corrosion resistant teletransmission glass rotameter of new construction for solving the problem of above-mentioned prior art.
The utility model has adopted following technical proposal to solve its technical matters: a kind of corrosion resistant teletransmission glass rotameter, comprise tapered glass tube, this tapered glass tube is built-in with rotor, tube wall is provided with scale, it is characterized in that: rotor is built-in with magnetic material, is fixedly equipped with row and the corresponding tongue tube of fluid flow in the tapered glass tube outside.
The utility model fluid by the time rotor height represent the size of flow, its pairing tongue tube is held by magnetic material, reed switch conduction is exported corresponding electric current by electronic circuit, but teletransmission shows flow to digital display meter and as the automatic control signal.Characteristics such as the utlity model has conveniently, simple, directly perceived, operating personnel are as long as just can be clear that at operation room flow indicates, and its cost only is 1/4 of original remote control liquid flowmeter, has saved production cost and user's use cost.

Embodiment
The utility model will be further described below in conjunction with embodiment and accompanying drawing.
With reference to Fig. 1, Fig. 2, the utility model comprises tapered glass tube 1, and this tapered glass tube 1 is built-in with rotor 2, and tube wall is provided with scale 3.
With reference to Fig. 3, Fig. 4, inlay high energy permanent magnet material 2.1 in the rotor 2 described in the utility model, the outside of tapered glass tube 1 is fixedly equipped with a row and the corresponding tongue tube K of fluid flow, and this tongue tube K is fixed on the insulcrete 4, and insulcrete 4 fixes with the outer wall of tapered glass tube 1.
With reference to Fig. 5, Fig. 6, tongue tube K described in the utility model is serially connected in the electronic circuit.
The electronic circuit that the utility model adopted can make keep synchronously through the fluid flow size of flowmeter electric signal size with output.
In electronic circuit, by resistance R
0, variable resistor W
1, voltage stabilizing diode D
1The stabilized voltage supply of being formed is by variable resistor W
1Can regulate V
bThe point voltage value.Resistance R
1-R
100And tongue tube K
1-K
100Be connected in the circuit, and by adjusting resistance W
2Be connected with the emitter of transistor T, and equidistantly stationary arrangement is on insulcrete 4, when having fluid to pass through in the flowmeter, rotor 2 rises, and certain tongue tube K contact is by adhesive, and transistor T is output current I just
cFluid flow is big more, and rotor 2 is high highly more, output current I
cAlso just big more, on the contrary electric current I
cJust reduce.So just can reach the variation that the size variation of fluid flow is converted into the output current size, thereby provide effective signal for digital display or automatic control.
