Multichannel ultrasonic flow rate measurement mechanism flow sensor

Technical field

The utility model relates to a kind of flowmeter parts, specifically multichannel ultrasonic flow rate measurement mechanism flow sensor.

Background technology

Known ultrasonic flow rate detection flow sensor, is on the outer wall of sensor body, and corresponding Upstream section front side (as Fig. 1) is equiped with row's upstream transducer socket.On the outer wall of sensor body, corresponding tract rear side (as Fig. 1) is equiped with row's downstream transducer socket, and each transducer socket is laid by parallel distribution mode.In each transducer socket, be inserted with a transducer, have the shortcomings such as fluid flow measuring speed is slow, and error is large.

Utility model content

The purpose of this utility model, is to provide multichannel ultrasonic flow rate measurement mechanism flow sensor, can effectively improve measurement and the measuring accuracy of fluid media (medium) flow, flow velocity.

The technical scheme adopting is:

Multichannel ultrasonic flow rate measurement mechanism flow sensor, comprises body, and there is respectively flange at the two ends of body, it is characterized in that:

Flow to fluid media (medium), body is divided into Upstream section and tract.On the tube wall of corresponding Upstream section along circular direction, and by radiation battle array arrangement mode, be fixed with at least one row's upstream transducer socket, every row's upstream transducer socket has 6 at least, the axial inclination θ of each upstream transducer socket and body is 5-85 degree, and equivalent distance equates.

On the tube wall of corresponding tract along the circumferential direction, and be fixed with at least one row's downstream transducer socket by radiation battle array arrangement mode, every row's downstream transducer socket has 6 at least, and the axial inclination θ of each downstream transducer socket and body is 5-85 degree, and equivalent distance equates.

Every row's upstream transducer socket is identical with the parameter of corresponding row's downstream transducer socket, position is corresponding respectively, and opposite direction.

In each upstream or downstream transducer socket, be inserted with ultrasonic transducer.

Principle of work:

The utility model is that multichannel device for measuring ultrasonic wave flow supports the use.Adopt ultrasonic transducer stage construction, multichannel, multi-faceted, many incident and leggy method for arranging (as Fig. 3).Any one transducers transmit ultrasonic waves of upstream, the whole transducers in downstream acknowledge(ment) signal simultaneously, any one transducers transmit ultrasonic waves of downstream, the whole transducers in upstream receive signal simultaneously, are not to transmit and receive one to one.Between sound channel and sound channel, be interweaved like this, just formed sound channel net, calculate the velocity of medium on each and every one point of crossing between sound channel and sound channel by computing machine, the flow of energy Accurate Measurement liquid medium.

The flow measurement of the utility model fluid medium not only speed is fast, and error is little.
