Abstract
The utility model discloses an electric-quantity-outputting type glass rotameter which comprises bases, an encloser and a cone-shaped glass tube, the encloser is installed between the two bases, the cone-shaped glass tube is installed in the encloser, a metal floater is installed in the cone-shaped glass tube, a proximity switch is installed on the encloser, the position of the proximity switch corresponds to that of the metal floater, and the proximity switch is an inductive switch. When a flow rate changes, switching signals can be output to connect a warning device, a worker can find the change of the flow rate in time, and bad consequences are prevented from occurring.
Description
Technical field
The utility model relates to a kind of glass rotameter, relates in particular to a kind of electric weight output type glass rotameter.
Background technology
At present, the main measuring sensor of known glass rotameter is a vertical transparent Taper Pipe and at the interior metal floater that can move up and down, the fluid Taper Pipe of flowing through from bottom to top during work, and the equilibrium position of float can indicate measuring of flow.But this flowmeter only can be indicated flow, can not export electric quantity signal to drive warning device when flow changes, and in unattended place, the variation of flow can not be found timely, so that produced adverse consequences.
Summary of the invention
The purpose of this utility model provides a kind of electric weight output type glass rotameter, can export the switching value signal when flow changes, and is connected to can control warning device in the external circuit and send alerting signal.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of electric weight output type glass rotameter, comprise pedestal, case, tapered glass tube, between two pedestals case is installed, case is installed tapered glass tube, it is characterized in that: metal floater is installed in the tapered glass tube, install near switch on the case, corresponding with the position of metal floater near switch, be inductive switch near switch.
According to described electric weight output type glass rotameter, it is characterized in that: described case center is opened a rectangle hole along the vertical direction, and length can cover most of scale, and width is the diameter near switch, is installed on this mouthful near switch.
The utility model has the advantages of and be: can when flow changes, connect warning device by output switching signal, allow the staff in time find the variation of flow, avoid producing adverse consequences.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In the accompanying drawing: 1, pedestal; 2, case; 3, tapered glass tube; 4, metal floater; 5, near switch.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
The utility model as shown in Figure 1, a kind of electric weight output type glass rotameter, comprise pedestal 1, case 2, tapered glass tube 3, case 2 is installed between two pedestals 1, case 2 is installed tapered glass tube 3, it is characterized in that: metal floater 4 is installed in the tapered glass tube 3, is installed near switch 5 on the case 2, corresponding with the position of metal floater 4 near switch 5, be inductive switch near switch 5.According to described electric weight output type glass rotameter, it is characterized in that: described case 2 centers are opened a rectangle hole along the vertical direction, and length can cover most of scale, and width is the diameter near switch 5, are installed on this mouthful near switch 5.
The utility model installs one near switch 5 in tapered glass tube 3 outsides of flowmeter over against the equilibrium position of metal floater 4, metal floater 4 is within the distance of reaction near switch 5, can be fixed on a certain scale and be within the distance of reaction near switch 5 near switch 5, this moment, the electric weight near switch output was off-state.When flow changes consequently metal floater 4 generation displacements, if the displacement of metal floater 4 exceeds the induction range near switch 5, then recover normally offs near switch 5, make external circuit connect warning device and send alerting signal.
On the case 2 of glass rotameter, open a rectangle hole along the vertical direction in the center, length can cover most of scale, width is the diameter near switch 5, be installed on this mouthful near switch 5, and can move up and down along tapered glass tube 3, be fixed in needed scale position.During operate as normal, metal floater 4 must be within the distance of reaction near switch 5.Be connected in the external circuit near switch 5, be used for the control warning device.
Can when flow changes, connect warning device by output switching signal, allow the staff in time find the variation of flow, avoid producing adverse consequences.
Embodiment recited above is described preferred implementation of the present utility model; be not that design of the present utility model and protection domain are limited; under the prerequisite that does not break away from the utility model design concept; common engineering technical personnel make the technical solution of the utility model in this area various modification and improvement all should fall into protection domain of the present utility model.
