Abstract
The invention relates to a liquid flow monitor. The liquid flow monitor comprises a liquid flow detecting system and an electronic control system. The liquid flow detecting system comprises an optoelectronic switch sensor and a protecting cover. The optoelectronic switch sensor transmits a detected liquid flow signal to the electronic control system. A control signal is output by the electronic control system. Due to the fact that the optoelectronic switch sensor is utilized by the liquid flow monitor, liquid flow can be detected in a non-contact mode, the corrosion or/and the abrasion on the liquid flow monitor by liquid can be avoided, the liquid flow monitor can be made of materials which are low in cost, the service life of the liquid flow monitor can be prolonged at the same time, and the device cost is obviously lowered.
Description
Technical field
The present invention relates to a kind of fluid flow watch-dog, particularly a kind of fluid flow watch-dog that is flow detector with optoelectronic switch sensor.
Background technology
Very general in enterprise by Cemented filling liquid, need in many cases to detect fluid flow or control, therefore flowmeter obtains extensive application as modal flow detector.Liquid involved by factory is varied, than if any various chemicals, or the sewage containing chemicals, or other contains the liquid of various solid particle, impurity.Permitted multi-chemical and be there is different corrosivity, the serviceable life of flowmeter can be reduced.In practical application, for the flowmeter that different chemicals often uses different corrosion-resistant material to make.In fact, even common flow meters price is just higher, and if flowmeter adopts erosion-resisting material to make, then the cost of flowmeter is just higher; If when containing solid particle in addition in liquid, easily flow meter causes wearing and tearing again, reduces the serviceable life of flowmeter.Therefore, carry be corrosive or/and the liquid of solid particle time, the cost of use traffic meter is just very high.
Summary of the invention
In order to solve the problem, the invention provides a kind of fluid flow watch-dog using optoelectronic switch sensor as flow detector, greatly can reduce equipment cost.
Technical scheme provided by the invention is: a kind of fluid flow watch-dog, comprises fluid flow detection system and electric-control system; Described fluid flow detection system comprises optoelectronic switch sensor.Optoelectronic switch sensor outputs to electric-control system the fluid flow rate signal detected, then exports control signal by electric-control system.Use optoelectronic switch sensor, non-contact detecting fluid flow can be realized, avoid liquid to its corrosion or/and wearing and tearing.
The outer setting of optoelectronic switch sensor has protective cover, and can not be subject to external destruction or interference by available protecting sensor, the outlet of liquid delivery tube is also arranged in protective cover.
As further optimization, protective cover is made up of lighttight waterproof material, can prevent the exotic such as high light or rainwater from causing interference to detection.
As further optimization, what the light beam launched of optoelectronic switch sensor and institute surveyed liquid flows to square crossing, to ensure the accuracy of measurement.
Present invention employs flow detector and institute's tracer liquid cordless, liquid can be avoided its corrosion caused or/and wearing and tearing, therefore can make by the cheap material of use cost, and extend the serviceable life of flow detector simultaneously, significantly reduce equipment cost.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of fluid flow watch-dog
Embodiment
As Fig. 1, this fluid flow watch-dog, comprises fluid flow detection system 1 and electric-control system 2; Described fluid flow detection system 1 comprises flow detector 3, and flow detector 3 is specially optoelectronic switch sensor 3.Optoelectronic switch sensor 3 light beam 7 launched and the liquid 6 flowed out from liquid delivery tube 5 flow to square crossing, be conducive to accurate sensed light signal like this.Optoelectronic switch sensor 3 outputs to electric-control system 2 after the light signal fed back from liquid 6 is converted into electric signal, has outputed signal the control to miscellaneous equipment by electric-control system 2.
In order to avoid rainwater, sunlight, incandescent light and other exotic cause interference or damage to optoelectronic switch sensor 3 work, the outer setting of optoelectronic switch sensor 3 has protective cover 4, and the outlet of liquid delivery tube 5 is also arranged in protective cover 4.Protective cover preferentially selects lighttight waterproof material to make, as PVC, PE, PP, zinc-iron skin, corrosion resistant plate etc.
By reference to the accompanying drawings detail explanation has been done to embodiments of the present invention above, but the present invention is not limited to above-mentioned embodiment, in the ken that those of ordinary skill in the art possess, various change can also be made under the prerequisite not departing from present inventive concept.
