Abstract
The utility model relates to an internal digital display target type flow meter, which is composed of a data processing device, a sensing device and a sampling device, wherein, the data processing device is composed of a signal processing circuit and a display; the sensing device comprises a sensor seat and a sensor; the sampling device comprises a target rod and a target sheet fixed on the target rod. The sensor is composed of a metal strain barrel body and a strain sheet arranged on the inner wall of the barrel body; the target rod is fixed out of the barrel body of the sensor; a gap does not exist between the sensor and the target rod; consequently, the internal digital display target type flow meter can be used in various liquids containing impurities. The utility model has the advantage of wide range of application.
Description
The utility model relates to a kind of industrial flowmeter.
Flowmeter is widely used in the fluid flow metering and the control of industrial sectors such as oil, chemical industry, metallurgy, generally the target sheet is loaded in tank body or the pipeline, fluid flows and acts on sensor through target sheet and machine driven system, convert electric signal to by sensor again, after signal processing circuit calculates fluid flow, the flowmeter structure complexity of this structure, error are big.The patent No. is 98241837 (notification numbers 2343576, October 13 1999 day for announcing) utility model provides a kind of high-precision digital display target type meter, it mainly is made of gauge outfit, sensor, target sheet and cavity, gauge outfit includes conventional Computer signal and handles and display, be connected with sensor signal output, the target sheet is fixed on the target bar, sensor is selected cartridge type stress-strain sensor for use, be sheathed on target bar periphery, and directly be provided with and be fixed in the cavity, have reliable, simple in structure, accuracy is high, usable range is wide, characteristics such as easy to operate.The sensor sleeve of this flowmeter is located at outside the target bar, is full of detected fluid in the gap of target bar and sensor, and when fluid contains assorted morely, the target bar is stuck stiff easily, and flowmeter can't be measured.
The purpose of this utility model is a kind of flowmeter that adopts built-in sensor of design, and it has accurate measurement, advantage of wide range of application.
Built-in digital display target type meter, constitute by data processing equipment, sensing device and sampling apparatus, data processing equipment is made up of signal processing circuit and display, sensing device comprises sensor holder and sensor, sensor is made up of metal strain cylindrical shell and the foil gauge of being located at cylinder inboard wall, sampling apparatus comprises target bar and the target sheet that is fixed on the target bar, and the target bar is fixed in outside the cylindrical shell of sensor.
Because the foil gauge of sensor places in the metal strain cylindrical shell, the target bar is located at outside the metal strain cylindrical shell, and there are not the space in sensor and target bar, therefore can both use in various containing in the assorted fluid, has advantage applied widely.
Below in conjunction with drawings and Examples the utility model is described in further detail
As figure is the structural drawing of the utility model digital display target type meter.
Built-in digital display target type meter is made of data processing equipment, sensor device and sampling apparatus, and data processing equipment 1 comprises signal processing circuit and display, and data processing equipment is arranged on the sensor holder 3 by holder 2.Sensor 4 is fixed on the sensor holder 3, and sensor 4 comprises metal cylinder 5 and the foil gauge 6 that is arranged on the inwall, and foil gauge 6 is connected with data processing equipment 1 by lead 7.Target bar 8 is fixed in outside the metal cylinder 5, and target sheet 9 is located on the target bar 8.
During use, target sheet 9 is arranged in tank body or pipeline 10, and fluid flow function is in target sheet 9, through target bar 8, acting force put on make it to produce miniature deformation on the metal cylinder 5, foil gauge 6 is converted into electric signal with the mechanical deformation amount, reach data processing equipment 1, processes and displays goes out the flow of fluid as calculated.
