The invention discloses a constant-volume weighing fluid dynamic metering device, which is used for weighing and metering a fluid in an online uninterrupted conveying state. The constant-volume weighing fluid dynamic metering device mainly consists of an automatic liquid reversing valve bank, a damping corrugated pipe, a liquid volume fixing device, a weighing device and a data acquiring and processing system, wherein a damping connection base and the automatic liquid reversing valve bank are fixedly arranged at one end of the upper plane of a base; in the liquid volume fixing device, a volume pipe is arranged between an upper end cover and a volume pipe base, and a central guide pipe and a piston are fixedly arranged on the upper end face of the volume pipe base; the lower part of the volume pipe base is provided with the weighing device; and a signal line is connected between a weighing sensor and the data acquiring and processing system. The constant-volume weighing fluid dynamic metering device has the effect of realizing automatic constant-volume weighing of the detected fluid, and metering the weight, the volume and the density of a liquid, gas or multi-phase fluid for displaying and storing. The device has intuitional and reliable metering accuracy and stable performance, can be widely applied to online dynamic metering of fluids, and is a large technological breakthrough in the field of dynamic fluid metering.
Description
technical field [0001] The invention relates to weighing measurement of liquid, gas or multi-phase mixed fluid in an on-line uninterrupted conveying state, and is a constant volume weighing type fluid dynamic metering device. Background technique [0002] Fluid metering technology is an important basic technology for the development of modern science and technology, among which weighing metering technology is the earliest and most intuitive and credible metering method used by humans. With the advancement of science and technology, modern measurement has entered dynamic measurement from static measurement, and weighing measurement technology cannot perform measurement under fluid dynamics. And other measurement methods: volumetric, plate-hole, and precession vortex dynamic measuring instruments, the measurement accuracy is greatly affected by the fluid flow pattern and flow state such as fluid pressure, temperature, viscosity, and density, and the mechanical structure is rel...
