FIELD: measurement technology; liquid flow metering in domestic and industrial conditions. SUBSTANCE: flowmeter has case with working space accommodating impeller, inlet and outlet holes forming, together with space, channel around impeller, and two protruding quadrants intended to build up increased hydraulic pressure within space between inlet and outlet holes, on both ends of impeller. EFFECT: improved reliability, enlarged measurement range due to balanced radial loads on impeller. |
