Abstract
The utility model relates to a display device for fluid measuring, comprising three sections of a turbine transmitter, a magnetoelastic transducer and a flow indicator. When measured medium flows across the turbine transmitter, the turbine is impelled to rotate, causing the magnetic field of the induction coil of the magnetoelectric transducer to vary periodically; thus electrical pulse signals corresponding to the flow rate are induced out. The signals are magnified and processed to display, realizing the measuring of fluid. The utility model has the advantages of simple structure, easy installation, easy use and damage resistance, directly displaying the total input and output amount of fluid. The utility model can be used for measuring inflammable and explosive substances such as gasoline, etc. provided with superior explosion proof performance particularly.
Description
The utility model relates to a kind of fluid metering display device.
Fluid metering is a job of generally carrying out in the industrial and agricultural production, and is then more general as departments such as chemical industry, oil.Fluid metering instrument with regard to present has simple graduated cylinder, measuring cup, and the fuel charger, dosing machine of electromechanical integration etc. are also arranged, and kind is more, and divides a lot of kinds, model again according to the type of fluid difference of metering.At present, the kind of oil depot POL measuring device is very single, and what generally adopt is gear meter, and its major defect has 2 points: the first is very easily damaged under drift angle, particularly is subjected to the gasoline medium influence, generally can only use one month; It two is no overall function of measuring, can't learn that oil plant is into and out of total amount from flowmeter.Because this two big defective, metering makes troubles to oil depot on the one hand, and equipment replacement is frequent, directly produces economic loss on the other hand, and brings difficulty for the oil depot POL management, and tax evasion oil phenomenon is difficult to control.
The purpose of this utility model provides a kind of fluid metering display device, makes it not fragile, can directly show fluid into and out of total amount, and has good explosion-proof performance.
To achieve these goals, the utility model has adopted following technical proposals: it comprises turbine transducer [1], magnetoelastic transducer [4], flow indicator [5] etc. this fluid metering display device.Turbine transducer [1] is that two ends are provided with the ring flange siphunculus, be provided with one in the middle and measure blind hole, measured hole is vertical with turbine transducer [1] center line, a ring flange recessed step in turbine transducer [1] two ends also is provided with pressing plate [3], locate turbine [2] between the pressing plate [3], turbine [2] is over against the measured hole center line.Magnetoelastic transducer [4] is a round box, and its measuring head stretches in turbine transducer [1] measured hole, and its magnetoelectricity change-over circuit is by inductance L, capacitor C
