Abstract

The utility model relates to a vortex flowmeter with simple structure and wide measuring range. A gas supersonic vortex flowmeter, which is composed of a flow sensor and a flow totalizer. The utility model is characterized in that the flow sensor is a supersonic vortex flow sensor which is composed of a meter body, a vortex generating body and a supersonic probe, wherein, the supersonic probe is quasi-associated with a liquid vortex area, and the vortex generating body is positioned at the middle part of a flow channel that the liquid flows across. The utility model is used for detecting flow.

Description

The gas supersonic vortex flowmeter
Technical field
The utility model relates to flowmeter, refers in particular to a kind of swirl flowmeter.
Background technology
Vortex (vortex street) flowmeter of at present domestic and international widespread use, though be a kind of relatively simple for structure, performance still belongs to superior fluid oscillation formula flowmeter, because its detecting device detection is the fluid oscillation signal, detecting device must have very high sensitivity, just can finish Measuring and testing.When, pipeline vibration little at flow is big, detecting device also can detect the vibration interference signal simultaneously, directly influenced the resistance to shock of instrument, particularly during measurement gas, because density is low, the signal that produces is very weak, can only strengthen signal intensity by improving the lower limit flow, has therefore limited the measurement range of instrument.In addition, the gas ultrasonic flow meter is because the technical difficulty height, the calculation procedure complexity, so manufacturing cost is very high.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, advantage of being convenient to make of existing swirl flowmeter, and the gas supersonic vortex flowmeter of the function that resistance to shock is good, measurement range is wide of ultrasonic flow meter is arranged again.
The purpose of this utility model is achieved in that gas ultrasound wave swirl flowmeter, it is made up of flow sensor and flow integrator, it is characterized in that: this flow sensor is the supersonic vortex quantity sensor, and the supersonic vortex quantity sensor is made up of table body, vortex generation body and ultrasonic probe, the accurate convection cell vortex of ultrasonic probe zone wherein, and vortex generation body is positioned in the middle of the runner that fluid flows through.
The main key of the utility model is to detect vortex frequency by the employing ultrasonic technique, has reached following purpose:
1, got rid of vibration interference;
2, enlarged flow range;
3, measurement accuracy, reliability and stability have been improved;
4, expanded the scope of application.
That is to say that it has kept the premium properties of swirl flowmeter, overcome the restricted deficiency of resistance to shock difference and measurement range; Kept simultaneously the good function of ultrasonic flow meter again, avoided its technical difficulty big, the weakness of calculation procedure complexity, manufacturing cost have also obtained reduction.

Fig. 1 is the utility model master TV structure synoptic diagram;
Fig. 2 is the utility model table body cross-sectional schematic.
Embodiment
As shown in Figure 1, 2: the utility model is made up of flow sensor A and flow integrator B, it is characterized in that: this flow sensor A is the supersonic vortex quantity sensor, and the supersonic vortex quantity sensor is made up of table body 11, vortex generation body 12 and ultrasonic probe 13, ultrasonic probe 13 accurate convection cell vortex zones wherein, and vortex generation body 12 is positioned in the middle of the runner that fluid flows through.Wherein, the vortex generation body 12 in the supersonic vortex quantity sensor fluid course is a column type; Wherein, ultrasonic probe 13 is installed on the fluid course vortex generation downstream line; Wherein, ultrasonic probe 13 quantity are more than 1 or 1; Wherein, ultrasonic probe 13 is vertical, levels or tilts to install; Wherein, more than one probe 13 is installed in same cross section or front and back symmetry or asymmetric installation.
The utility model integrates ultrasonic flow meter and swirl flowmeter, adopts ultrasonic measurement technology for detection vortex street vortex frequency, has overcome above-mentioned existence deficiency.It has following advantage:
1, the vortex street principle of swirl flowmeter has guaranteed the linearity of instrument.Adopt the Ultrasonic Detection vortex frequency, do not need very high accuracy requirement and complicated calculating just can satisfy measuring requirement, reduced the ultrasonic technique difficulty.
2, pipeline vibration can not produce interference to ultrasound wave, has improved resistance to shock.
3 so the very low flow velocity of ultrasound wave energy measurement, enlarged flow range.
