In this way, the flow distributer device of the Coriolis mass flowmeter sensor can solve the problem that the performance of the sensor is influenced by welding deformation of the flow distributer device.
Description
Technical field
The present invention relates to sensor technical field, relate 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, in petrochemical industry, be widely applied.
Mass flowmeter is by sensor, and transmitter and numeral indication 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 be take 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.When 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.When 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.When 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 when mass rate increases, this phase differential also increases, and by being installed on electromagnetic signal detecting device on import and outlet measuring tube, can record phase differential.
Mass flow sensor of the prior art comprises two shunts, these two shunts weld together with upper shell, the support bar of sensor respectively, yet, because the position of needs welding is more, inevitably welding deformation can affect the performance of sensor, causes the decline of measuring accuracy.
Therefore, how to avoid the problem that sensor performance impacted because of shunt welding deformation, become those skilled in the art's important technological problems to be solved.
Summary of the invention
The invention provides a kind of diverter unit of Coriolis mass flowmeter sensor, it can solve the problem that affects sensor performance because of shunt welding deformation.The present invention also provides a kind of Coriolis mass flowmeter sensor that comprises above-mentioned diverter unit.
