Иэсйретение относитсй к приборостроению и ж)жет быть использовано дл  измерени  объемов емкостей и резервуаров в различных отрасл х народного хоз йства и науки.The design relates to instrument making and can be used to measure the volumes of containers and reservoirs in various branches of the national economy and science.

Известен акустический способ измерени  объема емкости по собственной частоте колебаний газа, например воздуха , заключенного в этой емкости 1.An acoustic method is known for measuring the volume of a vessel by its own frequency of oscillation of a gas, for example, air contained in that vessel 1.

Недостатком известного способа  вл етс  невысока  точность измерени  ввиду того, что собственна  частота колебаний газа зависит от скорости звука в нем, котора  в свою очередь зависит от температуры газа.The disadvantage of this method is low measurement accuracy due to the fact that the natural frequency of gas oscillations depends on the speed of sound in it, which in turn depends on the temperature of the gas.

Цель изобретени  - повышение точности измерени  объема емкости.The purpose of the invention is to improve the accuracy of measuring the volume of the container.

Указанна  цель достигаетс  тем, что в нем после измерени  собственной частоты колебаний заключенного в емкости газа, в емкость ввод т заданное количество другого газа, отличающегос  от первого газа удельным весом и показателем адиабаты и измер ют собственную частоту колебаний образованной в емкости газовой смеси, а объем емкости определ ют по формулеThis goal is achieved by the fact that, after measuring the natural frequency of oscillations of a gas enclosed in a vessel, a specified amount of another gas is introduced into the vessel, different from the first gas by specific gravity and adiabatic index, and the natural frequency of the gas produced in the vessel is measured. containers are determined by the formula

На чертеже приведена принципиальна  схема устройства, иллюстрирующа  один из возможных примеров реализации акустического способа измерени  объема емкости.The drawing is a schematic diagram of the device, illustrating one of the possible examples of the implementation of an acoustic method for measuring the volume of a container.

Устройство содержит емкость 1, микрофон 2, усилитель 3 динамическую головку 4, частотомер 5 и емкост 6 с отличным от воздуха газом.The device contains a capacitance 1, a microphone 2, an amplifier 3, a dynamic head 4, a frequency meter 5 and a capacitance 6 with a gas other than air.

Измерение объема емкости 1 производ т следующим образом.The measurement of the volume of the tank 1 is carried out as follows.

Вначале с помощью микрофона 2, усилител  3, динамической головки Ц и частотомера 5 измер ют собственную частоту колебаний заключенного в емкости газа. Затем в емкость 1 из емкости 6 ввод т заданное количество другого газа, отлимащегос  от первого газа физическими характеристиками и измер ют собственную частоту колебаний образованной в емкости газовой смеси. Полученные результаты измерений в известные параметры газов подставл ют В: формулу.Hfj acчетным путем определ ют объем еНкости 1,First, using a microphone 2, an amplifier 3, a dynamic head C and a frequency meter 5, the natural frequency of oscillations of the gas enclosed in the capacitance is measured. Then, a predetermined amount of another gas, separated from the first gas by physical characteristics, is introduced into vessel 1 from vessel 6 and the natural frequency of oscillation of the gas mixture formed in the vessel is measured. The results of the measurements in the known parameters of the gases are substituted for the B: formula.

Применение изобретени  позвол ет измер ть объем емкости с повышенной точностью, благодар  тому, что исключаетс  температурна  погрешность измерени  вследствие того, что емкости 1 и 6 наход тс  р дом и температура газов в них  вл етс  практически одинаковой .The application of the invention makes it possible to measure the volume of the tank with increased accuracy, due to the fact that the temperature measurement error is eliminated due to the fact that the tanks 1 and 6 are near and the temperature of the gases in them is almost the same.

Расчетна  погрешность акуст ческого способа измерени  объема газа составл ет не более +0,05%.The calculated error of the acoustic method for measuring the gas volume is no more than + 0.05%.
