Rotating consistency transmitter and method

摘要: A rotating consistency transmitter (2) and method of measuring the viscosity, consistency, concentration or rheological properties a flowing multi-purpose material in pipeline (5) by torque acting on shaft (4), which at one end is driven motor (15) other attached to an impeller (14) directly positioned inside (5). The (4) made up three concentric shafts are aligned with each together so that single may be used rotate this (4). consists outer drive (19), middle sensor (23) inner reference (27). connected (19) opposite When present main contact (14), rotation impeded, thereby producing across (23). This causes twisting action determined angular displacement between measured passing focussed light beam two optical disks (28, 29), being amount transmitted through 29) direct measure which, turn, relates drag forces (14).
