The flow distributor comprises two distributor bodies which are provided with locating grooves for locating an upper shell of a locating sensor, so that the upper shell is welded after being located on the flow distributor bodies through the locating grooves. Accordingly, the flow distributor of the Coriolis mass flowmeter sensor can solve the problem that position errors can easily occur in the welding process of the flow distributor and the upper shell.
Description
Technical field
The utility model relates to sensor technical field, relates in particular to Coriolis mass flowmeter sensor and diverter unit thereof.
Background technology
Coriolis mass flowmeters, be called for short Coriolis mass flowmeter, it is a kind of instrument of utilizing fluid principle mobile and Coriolis force that generation is directly proportional to mass rate in vibrating tube to carry out direct measurement quality flow, it can be directly used in mass rate, density and the temperature of measuring media, have that measuring accuracy is high, range ratio is wide, the feature such as good stability, maintenance are low, be widely applied in petrochemical industry.
Mass flowmeter is by sensor, and transmitter and numeral instruction accumulator three parts form, and the sensor of Coriolis mass flowmeter is made according to Coriolis effect, comprises the parts such as measuring tube, electromagnetic driver and electromagnetic detector, shunt.Electromagnetic driver makes measuring tube with its natural frequency vibration, and the importing of flow makes U-shaped measuring tube produce a kind of distortion under the effect of coriolis force, the left and right sides at it produces a phase differential, and according to Coriolis effect, this phase differential is directly proportional to mass rate.Electromagnetic detector changes corresponding level signal into this phase differential sends into transmitter, after the electric weight such as filtering, integration, amplification is processed, is transformed into the simulating signal that is directly proportional to quality and two kinds of formal outputs of frequency signal of certain limit.
The measuring principle of mass flowmeter is taking newton's second law of motion as basis
F=ma
F-fluid force in formula; M-measured medium quality; A-acceleration.
When fluid is during by two parallel measuring tubes, can produce acceleration and a corresponding Coriolis force horizontal with flow velocity direction, this power makes measuring tube vibrate and be distorted, and this twisted phenomena is referred to as Coriolis phenomenon.
According to newton's second law of motion, the size of measuring tube twist angle is to be directly proportional to the size of the mass rate of the measuring tube of flowing through completely.In the time that fluid flows through measuring tube, fluid will be subject to the effect of Coriolis force, and the retroaction of the suffered Coriolis force of fluid in measuring tube produces the phase differential of import and outlet.In the time that fluid is zero, measuring tube vibrates under natural frequency, and measuring tube does not produce distortion, and the phase differential of fluid inlet and outlet is zero.In the time having fluid to flow through measuring tube, inflow point's tube vibration slows down, exit tube vibration accelerates, import produces phase differential with outlet, and in the time that mass rate increases, this phase differential also increases, and can record phase differential by being installed on electromagnetic signal detecting device on import and outlet measuring tube.
Mass flow sensor of the prior art comprises two shunts, and these two shunts weld together with upper shell, the support bar of sensor respectively, but, in welding process, shunt and upper shell are not easy location, and deviation easily appears in welding, and then affects the performance of sensor.
Therefore, how to solve shunt and upper shell in prior art and weld the problem of easy occurrence positions deviation, become those skilled in the art's important technological problems to be solved.
Utility model content
The utility model provides a kind of diverter unit of Coriolis mass flowmeter sensor, and it can solve the problem of easy occurrence positions deviation in shunt and upper shell welding process.The utility model also provides a kind of Coriolis mass flowmeter sensor that comprises above-mentioned diverter unit.
The diverter unit of a kind of Coriolis mass flowmeter sensor that the utility model provides, comprise two shunt main bodys, described shunt main body is provided with the locating slot for the upper shell of alignment sensor, so that described upper shell is positioned to weld after described shunt main body by described locating slot again.
So arrange, before shunt main body and upper shell are welded, can first upper shell be positioned in the locating slot of shunt main body, then weld again, so, avoided in welding process, there is the problem of dislocation in shunt main body and upper shell, has ensured the usability of sensor.
The utility model also provides a kind of Coriolis mass flowmeter sensor, comprises the diverter unit of the above.So arrange, the Coriolis mass flowmeter that the utility model provides has been avoided in welding process, and the problem of dislocation occurs for shunt main body and upper shell, has ensured the usability of sensor.
