Dextrin position signal should and be sent out to controller, controller automatically controls second solenoid valve (8b) closing, the first solenoid valve
(8a) is opened, and so as to make in capillary viscometer under atmospheric pressure environment, dextrin free flow, dextrin liquid level flows through high scale
The first video camera automatic sensing and controller is excited to start timing during line (5), dextrin liquid level flows through lower graduation mark and images at present
Machine automatic sensing simultaneously excites controller to terminate timing, and timing time is this delivery time t1, the delivery time continuously repeats
It measures 2 times, average value is delivery time t；
4), kinematic viscosity calculates：
Delivery time t is multiplied with the viscosity constant C of capillary viscometer, and result is the kinematic viscosity v of tested grain.
