FIELD: measurement technology. SUBSTANCE: water meter includes register and body with inlet and outer branch pipes and partition dividing internal space of body into inlet and outlet chambers. Four necks and cavity formed by circular partition of body with blank bottom sealed tight by plate where impeller is placed lead to finished plane of body. Two pairs of mutually parallel and axially symmetric grooves are made in circular partition, system of conduits ensuring division of flow of measured water into to equal parts is made between circular partition and walls of body, supply of water to grooves in circular partition, discharge of divided flow rates and their subsequent confluence. EFFECT: simplified design and ensured metrological stability of meter in the course of prolonged intervals between tests. 4 dwg |
