Correspondence position vertical with left transducer is provided with lower-left speculum on measurement pipe interior lower surface；Also include on upper reflector
Symmetrical right transducer and bottom right speculum；The ultrasonic wave that left transducer sends is anti-through lower-left speculum, upper reflector and bottom right
Mirror reflection rear right transducer is penetrated to receive；Thermistor is additionally provided with pipeline section.
Further, the left and right two ends of the measurement pipe, are provided with O-ring seal between pipeline section.
Further, location hole is provided with the measurement pipe, measurement pipe is fixed by location hole with pipeline section.
Further, mounting hole is provided with the thermistor and left transducer, thermistor and left transducer pass through
Mounting hole is fixed with pipeline section.
Further, the lower-left speculum and bottom right higher mirror are the 1/3 of measurement pipe caliber.
The beneficial effects of the utility model are：
(1) the utility model transducer is arranged on pipeline section top, it is not necessary to sets angle and is arranged on pipeline section inwall, pipeline section
Processing is simple；
(2) the utility model is provided with speculum in pipeline section inwall upper surface, increased the path of ultrasonic wave, improves measurement
Precision, reduces error；
(3) the utility model simple structure, certainty of measurement are high, practical.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
In figure：1- pipeline sections, 2- measurement pipes, 3-O type sealing rings, 41- lower-lefts speculum, 42- bottom rights speculum, 51- is changed on a left side
Can device, the right transducers of 52-, 6- thermistors, 7- upper reflectors.
Specific embodiment
The utility model is described further with specific embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of ultrasonic fluid measurement apparatus, including it is arranged on the measurement pipe 2 inside pipeline section 1；In measurement pipe 2
Between be provided with horizontal upper reflector 7 on inwall upper surface；The left upper part of pipeline section 1 is provided with left transducer 51；The inwall of measurement pipe 2
The vertical correspondence position of left transducer 51 is provided with lower-left speculum 41 on lower surface；Also include symmetrical on upper reflector 7
Right transducer 52 and bottom right speculum 41；The ultrasonic wave that left transducer 51 sends is through lower-left speculum 41, upper reflector 7 and the right side
The lower reflection rear right of speculum 42 transducer 52 is received；Thermistor 6 is additionally provided with pipeline section 1.
When using, the transmitting ultrasonic signal of left transducer 51 is transferred on lower-left speculum 41, by reflection；To upload
After the defeated reflection through upper reflector 7, then the received ultrasonic signal of right transducer 52 is transferred to after the reflection of bottom right speculum 42；So
Afterwards, the transmitting of right transducer 52 ultrasonic signal, is transferred on bottom right speculum 42, by reflection；Transmission is through upper reflector 7 upwards
After reflection, then the received ultrasonic signal of left transducer 51 is transferred to after the reflection of lower-left speculum 41；Transmitted twice by measurement
Time difference and thermistor 6 measurement temperature compensate, calculate fluid flow velocity and flow.
Further, the left and right two ends of the measurement pipe 2, are provided with O-ring seal 3 between pipeline section 1；Set O-shaped close
Seal 3, can prevent current from passing through the gap between measurement pipe 2 and pipeline section 1, cause measurement inaccurate.
Further, location hole is provided with the measurement pipe 2, measurement pipe 2 is fixed by location hole with pipeline section 1；Pass through
The location hole for pre-setting can cause that measurement pipe 2 is more prone to the assembling of pipeline section 1, accurate positioning.
Further, mounting hole, thermistor 6 and left transducer are provided with the thermistor 6 and left transducer 51
51 are fixed by mounting hole with pipeline section 1；By setting mounting hole, in that context it may be convenient to which thermistor 6 and transducer are installed into pipe
In section 1.
Further, the acclivitous height of the lower-left speculum 41 is the 1/3 of the caliber of measurement pipe 2；It can be fluid
The reserved sufficient space of flowing, the proper flow of fluid is not influenceed as far as possible, improves certainty of measurement.
The utility model solves transducer installation pedestal and changes angle difficult processing by changing transducer installation site
Problem；Increase reflecting plate in the upper surface of measurement pipe 2, increased ultrasonic wave transmission path in a fluid, the time difference will be more
Substantially, improve certainty of measurement；The angle of lower mirror tilt diminishes, and current can be allowed more unobstructed, and measured zone flow field is more preferable.
Preferred embodiment of the present utility model is the foregoing is only, is not used to limit the utility model, it is all at this
Any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
