Длинноволновый звук передают в измерительную трубу и с помощью двух звуковых детекторов, расположенных на некотором расстоянии L друг от друга и связанных с измерительной трубой, выявляют звуковые сигналы, которые распространяются в газе вниз и вверх по течению, при этом скорость V течения газа, проходящего по измерительной трубе определяют с помощью корреляции этих звуковых сигналов. Скорость Co(T) звука в находящейся в состоянии покоя среде записывают в память 20М, при этом скорость звука стандартизирована или будет стандартизирована для определенной температуры, и рассчитывают скорость V течения и другие величины, производные от нее, если они нужны, по крайней мере в случаях нарушения, с помощью выдавленной скорости Vd вниз по течению или выявленной скорости Vu вверх по течению и с помощью скорости Co(T) звука в состоянии покоя, записанной в памяти 20М.The long-wave sound is transmitted to the measuring tube and using two sound detectors located at some distance L from each other and connected to the measuring tube, they detect sound signals that propagate downstream and upstream in the gas, while the velocity V of the gas flowing through the measuring tube is determined using the correlation of these sound signals. The speed Co (T) of the sound in the quiescent environment is recorded in the memory 20M, while the speed of sound is standardized or will be standardized for a certain temperature, and calculate the flow velocity V and other values derived from it, if they are needed, at least violation cases, using the extruded speed Vd downstream or the detected speed Vu upstream and using the speed Co (T) of the sound at rest recorded in the 20M memory.
