Description
Technical field
The present invention relates to a kind of measurement apparatus, more particularly to a kind of open channel section flow measurement device.
Background technology
With the development of society, society is gradually paid close attention to water quality and the data of current, the flow measurement for water channel seems
The more next moon is important.The flow of open channel section is that flow velocity is multiplied by current device location section, and device probe uses acoustic Doppler
Effect measurement flow velocity, host computer acquisition process is then sent to, shows flow.The measurement of flow velocity (is changed by ultrasonic probe
Can device) transmitting with receive ultrasonic signal and do it is corresponding calculate handle and acquisition：The tranmitting frequency of transducer 1 is f1 ultrasound
Ripple signal, at a certain angle from launching under water to the water surface, after the suspended particulate or bubble in encountering water, frequency shifts,
And with f2 frequency hop to transducer 2, f2 and f1 difference are Doppler frequency difference fd.If rate of flow of fluid is v, ultrasonic velocity
Rate of flow of fluid v is proportional to for c, Doppler frequency-shift fd.Substantial amounts of impurity particle and bubble, each reflective particle pair are had in water
A Doppler frequency-shift fd is answered, its flow velocity can be tried to achieve by conversion, the mean flow rate of these a large amount of particles namely being averaged for fluid
Flow velocity.Traditional contactless biography sonic test limitation and the section section of irrigation canals and ditches require high, and need installing groove, cost
It is higher.
The content of the invention
The technical problems to be solved by the invention are：A kind of open channel section flow measurement device, this kind of open channel section are provided
Flow measurement device is easy for installation, can reduce maintenance cost.
Solve the technical problem, the technical scheme is that：A kind of open channel section flow measurement device, it includes aobvious

Put in case, by cable connection, the junction surface of described cable and sensor is provided with anti-for described display terminal and sensor
Water swivel.
Described water joint is made up of fittings body bucker, fittings body, fastener and fastener waterproof jacket, and described connects
Head body bucker and fittings body are to form integral structure, and described fastener and fastener waterproof jacket are to form integral knot
There are fittings body external thread section, cable patchhole and eight fittings bodies to collapse bar for structure, described fittings body, and described fittings body is prevented
Water cover is located at one end of fittings body, and eight fittings bodies collapse the other end that bar is located at fittings body, and described adjacent fittings body is received
Hold together between bar and be located at fittings body middle part with interval, described fittings body external thread section, described fastener has in fastener
Conical section and fastener internal thread segment, described fastener waterproof jacket are located at fastener end, described fastener female cone section
Away from fastener waterproof jacket, described fastener internal thread segment coordinates with fittings body external thread section, eight fittings bodies collapse bars with
Fastener female cone section presses.
The outer circumference surface of described fastener is provided with a plurality of raised ring of increase friction.
Structure as a kind of open channel section flow measurement device use of the present invention, it is easy for installation, maintenance cost can be reduced.
