Abstract
An eight-pass Coriolis mass flowmeter sensor is characterized in that one side of each divider is a plane, the other side of each divider is evenly provided with four sets of division cavities communicated with one another, each set includes two division cavities, rotation angle beta of each division cavity is 65 degrees, a guide post is disposed in the center of a pass penetrating the plane side of the divider, each flow tube is in a trapezoidal structure having an inner included angle alpha of 260 degrees, two ends of each set of flow tubes are communicated with the division cavities of two dividers, the trapezoidal structure of each flow tube faces out, the planes of the dividers are communicated with two flanges respectively. The eight-pass Coriolis mass flowmeter sensor has the advantages that the eight phi 57mm flow tubes vibrate at the same time after electrified with 220V direct current, mass of the flow tubes is reduced, the shape is modified from U shape to 130-degree trapezoid, the flow tubes vibrate more easily and more stably, vibration frequency is larger, an electronic commutator can process the stable signals more easily, and a zero point has a stable positive function during usage of instruments.
Description
Technical field
The present invention relates to the improvement to eight runner type coriolis mass flowmeters sensors.
Background technology
What the flowtube of coriolis mass flowmeters adopted at present is the U-shaped pipe of two external diameter φ 108mm, because this U-shaped pipe volume is large, cause flowmeter flowtube quality weight, when work, play vibration frequency low, accuracy of instrument is unstable zero point, often adjusts zero point between the operating period.Also there is the on-the-spot defects such as difficulty of installing simultaneously.
Summary of the invention
For overcoming the shortcoming of above-mentioned prior art, the invention provides a kind of improved eight runner type coriolis mass flowmeters sensors.
A kind of eight runner type coriolis mass flowmeters sensors, is characterized in that, shunting body one side is plane, and another side is uniform is set to four groups of shunting chambeies that mutually connect, and every component stream chamber is two, and the corner β in each shunting chamber is 65 °; In the passage connecting in shunting body plane one side, centre is provided with diversion column; Flowtube is trapezium structure, and interior angle α is 260 °; The two ends of every group of flowtube are communicated with respectively two shunting chambeies on shunting body, and the trapezoidal portions of flowtube outwardly; The plane of two shunting bodies is communicated with two flanges respectively.
Principle of work of the present invention is Coriolis principle, fluid, flows out from other end shunting body, at logical 220V direct current through flowtube from one end shunting body of pipeline, drive inductive coil, make flowtube produce vibration, according to Coriolis principle, will produce Coriolis force, out of phase detection signal on the pipeline of flowtube, calculate phase differential, according to this mathematical model, can draw by the quality of flowtube fluid.
Fluid of the present invention flows into eight φ 57mm flowtube through pipeline from eight shunting chambeies of one end shunting body, is then pooled to other end shunting body and flows out.After the logical 220V direct currents of eight φ 57mm flowtube, play shake simultaneously, because flowtube quality diminishes, shape by U-shaped make into 130 ° trapezoidal, flowtube plays shake and is more prone to, more steady, vibration frequency is larger.Electronic commutator is also more easily processed these signals stably, and to instrument, in the process using, zero point stability has played positive effect.Why flowtube selects 130 ° trapezoidal, is that the pressure loss is less because angle is larger, thus by flow cast be decided to be 130 ° trapezoidal, shunting so chamber corner β is 65 °.Diversion column plays the effect of a direct fluid in addition, also will effectively reduce the pressure loss
