Ecological Systems and Devices Annotation << Back The requirements to torrential devices for flowmeters-counters of water and process liquids Kargapol’tsev V.P. The main requirements to the automated torrential volumetric-mass calibration devices for liquid counters are formulated. The advantage of volumetric-mass device before volumetric apparatus is proved. The practical realization of the volumetric-mass torrential device is considered. The basic problems are listed by manufacture of the torrential devices.
