Abstract
The invention discloses a volumetric flowmeter which comprises an elastic metal plate. The metal plate is vertically fixed on the inner wall of a pipeline and can generate a certain shape change when fluid flows. According to the volumetric flowmeter, the flow is measured through the elastic metal plate and strain gauges, the structure is simple, the cost is low, and the different flow ranges can be measured by changing the metal plates with the different elasticities.
Description
Technical field
The present invention relates generally to fluid flow metering field, particularly relates to a kind of volumetric displacement meter.
Background technology
The development of flow measurement can trace back to hydraulic engineering and the water-supply systems in ancient times.The ancient Roman Caesar epoch have adopted orifice plate to measure the potable water water yield of resident.Within B.C. about 1000, ancient Egypt's weir method measures Nilotic flow.Water-level observation water yield size of the Dujiang weir hydraulic engineering application Aguarius mouth that China is famous etc.
Metering is industrial eyes.Flow metering is one of ingredient of measuring science technology, and it and national economy, national defense construction, scientific research have close relationship.Carry out this work; to ensureing product quality, enhance productivity, the development of the technology that advances science all has important effect; particularly in energy crisis, current era that industrial production automation degree is more and more high, the role and effect of flowmeter in national economy is more obvious.
Volumetric displacement meter is the one of flowmeter, in order to better by flow meter applications in production, need that volumetric displacement meter structure is simpler, cost is cheaper.
Summary of the invention
For solving problems of the prior art, the invention provides the volumetric displacement meter that a kind of structure is simple, with low cost.
For achieving the above object, the technical solution adopted in the present invention is: a kind of volumetric displacement meter, and comprise one and have flexible sheet metal, described sheet metal is vertically fixed on the inwall of pipeline, and when fluid flows, certain deformation can occur described sheet metal.
Further, described sheet metal both sides are fixed with two foil gauges, and two foil gauges are mutually vertical.
Further, described foil gauge is connected in bridge diagram, and the output terminal of electric bridge connects amplifying circuit, and amplification circuit output end connects display module.
Further, the variate of described foil gauge composition, realizes compensating to temperature simultaneously.
Advantage of the present invention is: utilize elastic metal sheet and foil gauge measuring flow, and structure is simple, with low cost, changes different flexible sheet metal and can measure different flow range.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further elaborated.
Fig. 1 is side structure schematic diagram of the present invention.
Fig. 2 is the structural representation of the present invention along duct orientation.
In figure: 1, sheet metal, 2, foil gauge, 3, pipeline.
Embodiment
A kind of volumetric displacement meter as shown in Figure 1, 2, comprise one and have flexible sheet metal 1, described sheet metal 1 is vertically fixed on the inwall of pipeline 3, and when fluid flows, certain deformation can occur described sheet metal 1.
It is mutually vertical that described sheet metal 1 both sides are fixed with two foil gauges, 2, two foil gauges.The side of sheet metal 1 is provided with a foil gauge parallel with sheet metal, the opposite side of sheet metal 1 be provided with one with the orthogonal foil gauge of sheet metal, two foil gauges present mutually perpendicular state, and are arranged on the both sides of sheet metal 1 correspondence.
As preferably, described foil gauge 2 is connected in bridge diagram, and the output terminal of electric bridge connects amplifying circuit, and amplification circuit output end connects display module.The flowing of pipe interior fluid can make foil gauge produce strain, and the size of strain is relevant with uninterrupted, by bridge diagram, strain is converted to electric signal.
As preferably, described foil gauge 2 forms variate, realizes compensating to temperature simultaneously.Described foil gauge can form differential metering system, achieves compensate function to temperature simultaneously.
Technical characteristic disclosed in above-described embodiment just of the present inventionly has embodiment, not as the restriction to technical solution of the present invention for explaining.
