The utility model has the advantages of simple structure, scientific and reasonable design, small volume, high accuracy, long service life, low requirements for the component of the flow, and the utility model provides an ultrasonic guided wave flow sensor which has convenient installment and maintenance and low cost.
Description
Technical field
The utility model belongs to the flow sensor field, especially a kind of supersonic guide-wave flow sensor.
Background technology
Present small-bore measurement of fluid flow mode mainly is divided into contact and contactless two kinds, in the gas meter, flow meter of residents, cold water meter, calorimeter, mostly be contact type measurement, promptly utilize the mechanical flow meter that the flow of small-bore fluid is measured, though this mode can access measurement result, its shortcoming is conspicuous: 1. perishable; 2. easy to wear; 3. precision is low; 4. the convection cell composition requires high; 5. the life-span is short; 6. installation and maintenance are higher than complexity and cost.Existing non-contact measurement mode is mainly based on the straight pipe type ultrasonic measurement, this kind mode can effectively improve the precision of measurement, and the composition of convection cell requires lower, but has following shortcoming: 1. measuring device part causes the generation of eddy current in fluid, has influenced the reception of signal; 2. the measurement component in fluid converges dirt easily, increases the pipeline internal resistance, causes the flow field shakiness, and linear measurement is relatively poor; 3. need watertight for sensor its extension line of ultrasonic measurement mode in pipeline, structure is complicated, and cost of manufacture is higher; 4. installation and maintenance are higher than complexity and cost.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of simple in structure, and design science is reasonable, and volume is little, precision is high, the life-span is long, the requirement of convection cell composition is low, supersonic guide-wave flow sensor convenient for installation and maintenance and lower-cost.
The utility model solves its technical matters and is achieved through the following technical solutions:
A kind of supersonic guide-wave flow sensor, constitute by ultrasonic transducer and measuring tube, ultrasonic transducer is two two ends that also are packed in measuring tube respectively, and wherein measuring tube is a bend pipe, and is respectively arranged with an import and outlet on the measuring tube of two ultrasonic transducer lower ends.
And the import of described ultrasonic transducer and measuring tube is the axis normal setting with outlet.
And described ultrasonic transducer is piezoelectric ceramic ultrasonic transducer, quartz crystal ultrasonic transducer, magnetostriction ultrasonic transducer or electromagnet ultrasonic changer.
And, the two-way ultrasonic transducer of described ultrasonic transducer for launching and can receiving, and this ultrasonic transducer is by the groove on its shell and the axial seal of grommet type seals realization and measuring tube.
Advantage of the present utility model and beneficial effect are:
1. the measuring tube of this supersonic guide-wave flow sensor is a bend pipe, and on the measuring tube of two ultrasonic transducer lower ends, be respectively arranged with an import and outlet, ultrasonic transducer is vertical setting with the import of measuring tube with outlet, fluid is flow through and wash away the ultrasonic transducer surface, thereby reduce the pollution of fluid impurity, the serviceable life of improving this sensor to this sensor.In equal measurement range, the volume of this sensor has reduced manufacturing cost much smaller than the straight pipe type ultrasonic sensor.
2. the measuring tube of this supersonic guide-wave flow sensor is that bend pipe makes ultrasonic guidance wave energy pass the diverse location of fluid for more than enough time, has overcome the influence that reaches friction force between the fluid inside between tube wall and the fluid, has improved measuring accuracy.
3. the ultrasonic transducer of this supersonic guide-wave flow sensor is packed in the two ends of measuring tube by screw thread, installs, debugging is convenient, shortened construction period, has reduced construction cost, and has safeguarded also more convenient.
4. the utility model is simple in structure, and design science is reasonable, and volume is little, precision is high, the life-span is long, the requirement of convection cell composition is low, is a kind of supersonic guide-wave flow sensor convenient for installation and maintenance and lower-cost.
