Description
Technical field
The utility model is related to a kind of ultrasonic fluid measurement device, flow velocity and flow for measuring gas, liquid.
Background technology
Country's ultrasonic fluid measurement pipeline section is generally made of energy converter and measurement pipeline section at present.Energy converter is typically mounted at
In the mounting hole on pipe measuring section both sides, and energy converter is direct alignment.The shortcomings that this kind of structure is that ultrasonic wave sound path compares
It is short, and energy converter installation section cannot coincide with tube wall well, be easy to form flow eddies, to influence supersonic wave metering essence
Degree.The utility model fundamentally solves the problems, such as that ultrasonic wave sound path is short and energy converter be not easy with tube wall it is identical, and long-term
It is verified in experiment.
Utility model content
Technical problem to be solved in the utility model is to measure fluid for existing ultrasonic fluid measurement device
Shi Shengcheng is short and energy converter installation and tube wall are not easy to coincide and the problem of influencing measurement accuracy, provides a kind of high certainty of measurement, easily
In the fluid measurement instrument of manufacture and assembly.
In order to solve the above-mentioned technical problem, the utility model uses following technical proposal：
A kind of ultrasonic fluid measurement device, including a measurement straight tube, the measurement straight tube is installed above, and there are two energy converters
With three reflection units, measuring straight tube front and back end has flow deflector.When a measurement is taken, formed successively pass through introducing port, flow deflector,
Ultrasound transducer means, reflection unit, measurement straight tube, reflector plate, ultrasound transducer means, a fluid measurement of export mouth are logical
Road.
The ultrasound transducer means are by magnetostriction type ultrasonic transducer or piezoelectric ceramic type ultrasonic transducer and non-
Metal material forms, and wherein ultrasonic transducer is wrapped up by the material completely, so as to avoid the contact directly with detected fluid,
Also deposition sundries is avoided.The nonmetallic materials should have good ultrasonic wave permeability, and be not likely to produce fouling.
The flow deflector is made of one or several sheet metals, and the quantity of sheet metal is true according to corresponding technical parameter
It is fixed.The characteristic for acting as improving fluid flow fields of flow deflector is preferably to carry out ultrasonic measurement.
It is described in the utility model to design all the way, may be used in practice all the way, two-way or multichannel design, can be better
Improve measuring accuracy and using effect.
The technique effect of the utility model is very prominent, is in particular in：Solves ultrasound in ultrasonic fluid measurement
The technical barrier that amount sound path is short and causes measurement accuracy not high has simple in structure, measuring accuracy height, manufactures easy for installation etc. excellent
Point can be widely applied to ultrasonic fluid measurement field.

Fig. 2 is the schematic cross-section of the utility model flow deflector
Description of symbols in Fig. 1
1,3 --- ultrasonic transducer 2,5,6---- reflection units
4,7 --- guide vane 8 --- introducing ports
9 --- export mouths 10 --- measure straight tube
Specific implementation mode
As shown in Figure 1, a kind of ultrasonic fluid measurement device, including a measurement straight tube 10, in the side for measuring straight tube 10
Ultrasonic transducer 1, reflection unit 2, ultrasonic transducer 3 are installed, reflection unit 5, reflection unit 6 are installed on the right side, measured
Pipeline section both ends are installed by flow deflector 4 and flow deflector 7.
The particular number of flow deflector is determined according to corresponding technical parameter.
The ultrasonic transducer is magnetostriction type ultrasonic transducer or piezoelectric ceramic type ultrasonic transducer.
The measuring principle of the utility model is：Fluid to be measured passes through introducing port 8, and followed by flow deflector 4, transducing
Device 3, measures straight tube 10, reflection unit 2, reflection unit 6, energy converter 1, flow deflector 7 at reflection unit 5, is finally flowed from export mouth 9
Go out.
Ultrasonic wave is sent to reflection unit 6 using ultrasonic transducer 1, then arrives reflector plate 2, then arrives reflection unit 5, then is arrived
Energy converter 3 obtains the time of a ultrasonic transmission, conversely, sending ultrasonic wave by energy converter 3 again, arrives reflection unit 5, then arrive
Reflection unit 2, then reflection unit 6 is arrived, then energy converter 1 is arrived, the time of primary reverse ultrasonic transmission is obtained, fluid flow rate is utilized
Influence relationship to ultrasonic transmission speed can measure corresponding parameter according to the time difference of ultrasonic wave round-trip transmission, into
And the flow velocity for flowing through the fluid for measuring straight tube 10 and flow can be calculated etc..
