Abstract
An indicator for measuring the flow of a liquid. The flow meter is an instrument which utilizes the axial force of liquid flow to push an impeller to rotate and the impeller reflects the flow with the rotating speed of the shaft of the impeller. The flow of the liquid is indicated in the form of an electrical pulse. The impeller and the circular grating rotate coaxially, a light emitter and a receiver of the photoelectric coupler are respectively arranged on two sides of the circular grating, sequential pulse signals can be measured, and digital quantity and analog quantity are finally obtained after the sequential pulse signals are processed by an amplifier shaper. They are all capable of linearly reflecting the instantaneous value of the liquid amount. The indicator ultimately displays the liquid flow per second (in kilograms). It has the advantages of good linearity, accurate indication, low cost, etc., and is an ideal instrument for measuring flow rate in industry.
Description
The utility model is an indicator of measuring fluid flow with a kind of form of photoelectric velocity measurement.Particularly be used on the liquid line liquid is directly carried out flow measurement and demonstration.
Find in the timing of investigation current flux.Early stage flow indicator all is mechanical structure mostly.For example: widely used propeller flowmeter---water meter and differential flowmeter.The flow indicator of the electromechanical that occur recent years is divided into condenser type, piezoelectric type, magneto-electric and ultrasonic type or the like according to different measuring methods, but their each have their own weak points.For example: induction, bad to LF-response, and for example: piezoelectric type, condenser type, its output power is little, the impedance height, complex process, and high to insulating requirements.
The purpose of this utility model is to provide a kind of use reliable and stable to industrial, make easy, cheap, of many uses, no matter the flow size can both rectilinearity indication, and its technical indicator and capability and performance all can with costliness, complicated flowmeter compares favourably.
The utility model is to utilize the axial force of liquid stream to promote impeller 1, and drive is installed in coaxial circular grating 2 rotations of.The inside and outside both sides of circular grating 2 are placed with illuminator 3 and receiver 4 respectively, the continuous light beam that is sent by illuminator cuts into interrupted light beam by grating, become to react grating through receiver 4 opto-electronic conversion and rotate the train pulse of speed and export to amplifier G2 amplification, be shaped to amplitude phase isopulse.This pulse can directly be exported, and provides automatic control system to use; Also can deliver to converter, convert analog quantity to, do the numeral demonstration, the litre number that on behalf of per second, its displayed value flow through.
The utility model place that has a wide range of applications.Except that general liquid, also can be used for opaque solution, as ink, former wet goods.
The utility model concrete structure and mutual relation are as shown in drawings
