Abstract
The utility model relates to a digital display target-type flowmeter, which can be widely used for metering the flow capacity of a fluid in fields, such as petroleum, natural gas, chemical industry, metallurgy, power generation, air conditioner, etc. The utility model is mainly composed of a meter head, a sensor, a target sheet, and a cavity body, wherein, the meter head comprises a signal handler of a conventional computer, and a display; the meter head is connected with the signal output of the sensor; the target sheet is fixed on a target rod; the sensor adopts a barrel type tensile strain sensor, and the sensor is sheathed at the periphery of the target rod and is directly arranged and fixed in the cavity body. The utility model not only reserves the advantages of wide field of application and reliability of the traditional target-type flowmeter, but also has the accuracy of a volumetric flowmeter. The utility model has the advantages of simple structure, high precision, simple and convenient operation, etc.
Description
The utility model relates to a kind of gauging instrument, particularly a kind of digital display target type meter, and the fluid flow that is widely used in fields such as oil, rock gas, chemical industry, metallurgy, generating, air-conditioning measures.
Conventional target formula transmitter relies on the target sheet to obtain acting force, is sent to sensing chip through mechanical lever systems, causes that the output of differential transformer changes, and passes through corresponding current detecting at last, compares and the integrating processing, measures fluid flow.Because conventional target formula transmitter has adopted a large amount of mechanical transfer mechanisms between induction mechanism and stressed target sheet, be induction mechanism and be subjected between the force mechanisms to flexibly connecting, and the wearing and tearing in generation mismachining tolerance, rigging error and the use, cause the error in the sampling process to increase, and complex structure, cost height.
The utility model purpose is a kind of digital display target type meter of design, mainly by adopting being rigidly connected between target sheet and the force transducer, places detected fluid and directly obtains strong signal, reaches accurate measurement, purpose reliable and simple in structure.
The purpose of this utility model is realized by following technical scheme: the digital display target type meter mainly is made of gauge outfit, sensor, target sheet and cavity, gauge outfit includes conventional Computer signal processor 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, cartridge type stress-strain sensor sleeve is located at the peripheral formation of target bar sampling mechanism, and directly setting is fixed in the cavity.The sensing element of target sheet, target bar, sensor directly places cavity, promptly directly places detected fluid, to obtain directly strong signal source.
The digital display target type meter that the utility model is designed, its maximum characteristics are to obtain strong signal in the detected fluid with being subjected to the target sheet of force mechanisms and force transducer to be rigidly connected to be placed on, the advantage that has not only kept target formula tradition flowmeter, promptly be applicable under the condition that contains impurity and silt in the most field of flow meters, particularly detected fluid and also can reliably use; Possessed the accuracy of volumeter simultaneously.Have simple in structure, accuracy is high, usable range is wide, characteristics such as simple to operation.
Accompanying drawing is among the utility model one-piece construction synoptic diagram figure: 1--gauge outfit 2--gauge outfit seat 3--sensor 4--target bar
5--target sheet 6--fluid 7--cavity
Embodiment:
Present embodiment includes gauge outfit 1, sensor 3, target sheet 5 and cavity 7 and constitutes, and gauge outfit is made of the Computer signal processor and the display of routine, and gauge outfit connects sensor signal output, and gauge outfit is fixed on the cavity 7 by gauge outfit seat 2; Target sheet 5 is fixed on the target bar 4, and sensor 3 is selected cartridge type stress-strain sensor for use, and sheathed target bar 4 peripheries that are fixed on directly are fixed in the cavity 1.When the acting force of fluid generation affacts on the target sheet, be equivalent to directly act on the sensor, sensing chip produces the trace variation and exports little varying signal on the sensor, handles through the computer processor of gauge outfit, and demonstrates measured flux.
