FIELD: measuring equipment, possible use for determining flow of liquid, gas and steam in force pipelines. ^ SUBSTANCE: device for measuring flow consists of measuring portion of pipeline, including, along direction of flow, series of diffuser and constrictor, connected through maximal cross-sections and having end engagement portions of one diameter with controlled pipeline. Along the movement of flow of environment, minimal and maximal cross-sections of device are connected by additional pipeline of small size, in tear of which counting flow meter is mounted. Scale of indications of counting flow meter is calibrated in range of assumed losses of flowing substance via controlled pipeline. ^ EFFECT: expanded dynamic range of flow alternation with simultaneously simplified measuring circuit. ^ 5 dwg |
