Problems solved by technology

[0002] When measuring the weight of the sample in the prior art, since the sample and the measuring instrument are in the same environment, when measuring the weight of a substance in a special environment, such as a vacuum, a special temperature and a pressure range, the measurer cannot pass the actual weight. There is a metering device to accurately meet the metering requirements; in addition, when metering toxic and corrosive media, the harsh measuring environment not only brings harm to the health of the meterer, but also affects the accuracy and service life of the measuring instrument

Embodiment 1

[0019] Referring to Fig. 1, the magnetic levitation metering device provided by this embodiment includes a measurement area, a magnetic force transmission area, a working state conversion area, a sample area, an environmental tube 41, a tube outer center rod 231 and a tube inner center Rod 232, the measurement area is composed of a load measurement deformable body 11, an electronic balance scale body 12 and two anti-seismic horizontal supports 13, and the magnetic force transmission area includes an electromagnet 21, a permanent magnet 22 and a group of position sensors 24, The working state conversion area includes a lifting frame 31, a lifting frame 32 and a pair of brackets 33, and the sample area includes a cooling area and a heating area, and a high-level pressure transmitter is arranged at the upper end of the environmental pipe of the cooling area 52. There is a high-level fluid pump 71 at the junction of the cooling zone and the working state transition zone; a high-lev...

Embodiment 2

[0026] The metering system used in this embodiment is the same as that in Embodiment 1, and the process of using the metering system to measure the fluid weight under special temperature and pressure is the same as the steps described in Embodiment 1, except that:

[0027] According to the density of the fluid in the environment pipe, adjust the high-level fluid pump 71 and the low-level fluid pump 72 as the inlet and outlet of the fluid. If the density is small, the low level is used as the fluid inlet and the high level is used as the fluid outlet.

Abstract

This invention discloses a kind of material weight metering method under special environment, it forms a metering system with a kind of magnetic suspension metering device, intelligent control device and computer system for dividing the sample circumstance and the measuring circumstance; with the adjusting and controlling of the position sensor and intelligent control device, realizing magnetic suspension situation; after realizing zero adjusting under the normal environment, setting the needed temperature and pressure, the intelligent control device intelligently adjusts and controls the temperature adjusting device and the pressure adjusting device according to the adjusting temperature and adjusting pressure command the computer system exports, to realize the zero adjusting under the set environment; after the environment in the adjusting environment pipe getting the set temperature and pressure, the material weight in the environment pipe is delivered to the measuring device of the out pipe non-touched by the magnetic force coupling function that are produced by the permanent-magnet in the environment and the electromagnet out of the environment, and the measuring device of the out pipe put the measuring signal into the computer system.

Description

technical field [0001] The invention relates to a measurement method, in particular to a measurement method for the weight of substances in a special environment. Background technique [0002] When measuring the weight of the sample in the prior art, since the sample and the measuring instrument are in the same environment, when measuring the weight of a substance in a special environment, such as a vacuum, a special temperature and a pressure range, the measurer cannot pass the actual weight. There are metering devices to accurately meet the metering requirements; in addition, when metering toxic and corrosive media, the harsh measuring environment not only brings harm to the health of the meterer, but also affects the accuracy and service life of the measuring instrument. Contents of the invention [0003] The object of the present invention is to provide a method for measuring the weight of substances in a special environment, so as to overcome the defects of the prior ...
