Description
Изобретение относитс к измерительной технике и может быть использовало при градуировке и поверке расходомеров газа. Известен способ градуировки и поверки расходомеров газа, основанньш ка Использовании образцового газового мер ика колокольного типа, состо щего из снабженного противовесом цилиндрического колокола, стенки которого погружены в вод ной раствор 1. Колокол поднимаетс , наполн сь воздухом от вентил тора гфи давлении, которое определ етс величиной груза, служащего противовесом колокола. После открывани крана, сообщающего подколокольное пространство мерника с повер емым прибором , начинаетс движение воздуха через прибор.The invention relates to a measuring technique and can be used in the calibration and calibration of gas flow meters. The known method of calibration and calibration of gas flow meters is based on the use of an exemplary gas bell-type measure, consisting of a cylindrical bell fitted with a counterweight, the walls of which are immersed in a water solution 1. The bell rises, filling air with pressure from the gt fan, which is determined the magnitude of the load that serves as a counterweight to the bell. After the opening of the valve, which communicates the subcolumn space of the measuring device with a calibrated instrument, the movement of air through the instrument begins.
Наиболее близким по технической сущности к предлагаемому вл етс способ, основанный на заполнении газом калиброванной емкости и измерении давлени в емкости в определенный промежуток времени при посто нной температуре, например, с помощью жидкостного манометра путем определени ра лости высот двух сталбов жид,кости (2J.The closest in technical essence to the present invention is a method based on filling a calibrated tank with gas and measuring the pressure in the tank for a certain period of time at a constant temperature, for example, using a liquid manometer by determining the difference in height of two liquid stalbones (2J.
Указанный способ сложен, а при измсpcfiHH .малых расходов газа имеет низкую точность.This method is complicated, and when measuring low gas consumption has low accuracy.
Цель изобретени - уг1рошение процесса 11змерени и повышение точности.The purpose of the invention is to improve the process of measuring and increasing accuracy.
Дли этого по предлагаемому способу калиброо .чи ii Поверки расходомеров газа, основанному на заполнении газом калиброванной емкости н измерени давлени в емкости с жидкостного и-образного манометра путем определени разности высот двух столбов жидкости манометра, U-образный манометр размещают внутри калиброванной емкости и дополнительно определ ют сумму высот двух столбов жидкости манометра.To this end, according to the proposed calibration method, gas calibration of gas flow meters, based on filling the calibrated tank with gas and measuring the pressure in the tank from the liquid u-shaped manometer by determining the height difference between the two columns of the manometer liquid, is placed inside the calibrated tank and additionally determined are the sum of the heights of the two columns of the liquid manometer.
На основе измерени су.ммы и разности высот двух столбов жидкости манометра опреде-л ют расход газа по соответствующей формуле.Based on the measurement of the sum.mm and the height difference between the two columns of the liquid of the manometer, the gas flow is determined using the appropriate formula.
На чертеже представлена схема устройства , реализующего предлагаемый способ илмерени .The drawing shows a diagram of the device that implements the proposed method or measurement.
