Apparatus for automatically recognizing cumulative flow number on flow meter head, and method thereof

Abstract

The invention provides an apparatus for automatically recognizing the cumulative flow number on a flow meter head, and a method thereof. The apparatus comprises an industrial camera, an inductive switch, and a computer that are connected mutually. The industrial camera includes a camera and a fixed base; a damping rotating shaft is connected between the side of the camera and the fixed base; a fixing mechanism is arranged at the rear end of the fixed base; and an auxiliary lighting mechanism is arranged at the front end of the fixed base. The fixing mechanism includes a first bending adjustingrod and a second bending adjustment rod; a telescopic sleeve is connected between the tail end of the first bending adjustment rod and the front end of the second bending adjustment rod; and a fixedclamp is connected to the tail end of the second bending adjustment rod. The auxiliary lighting mechanism includes a third bending adjustment rod; an illumination lamp is arranged at the tail end of the third bending adjustment rod; and a brightness adjustment knob is arranged at the illumination lamp. Therefore, the number displayed by the flow meter is collected conveniently and calculation is carried out conveniently.

Description

technical field [0001] The invention specifically relates to a device and a method for automatically identifying the accumulated flow number of the meter head of a flowmeter. Background technique [0002] Existing flow calibration device: There is a specific pipeline, a ball rolls from point A to point B in the pipeline, and the pipeline has a fixed volume from point A to point B. When the ball passes through points A and B, the switch is triggered and the light is turned on. Calibrators see that the light is on , Check the head of the flowmeter, record the current cumulative flow, subtract the cumulative flow at point A from the cumulative flow at point B, which is the flow measured by the flowmeter, and the difference between the flow value and the constant volume value is the error of the flowmeter. Since the fixed volume from point A to point B is small, the ball needs to be rolled from point B to point A again in the pipeline, and repeated many times. When the volume re...

AI Technical Summary

Problems solved by technology

Since the fixed volume from point A to point B is small, the ball needs to be rolled from point B to point A again in the pipeline, and repeated many times. When the volume reaches a certain amount, the calibration needs can be met. In actual operation measurement, there are generally two types: Method: 1. It is necessary to manually record the meter data, which is a waste of labor and the measurement data is not accurate; 2. Directly connect the flowmeter to the computer to process the data, but this method has high requirements for the flowmeter and does not have data Flowmeters with transmission functions and flowmeters that cannot be adapted to computers will not be collected; therefore, there is an urgent need for a device and method that can universally identify and calculate flowmeter head data
