The dynamic water filtering instrument of the utility model has two working modes, one working mode is to measure the filtered water volume within a specified time, and the other working mode is to measure the time required for the specified filtered water volume. The specific working process is as follows: put the measured slurry in the resin tank 2, start the motor 1 to stir, and open the flow valve 6 after the stirring speed is stable, and the water filtered out of the slurry passes through the rubber plug 4 and the rubber tube 5 And glass tube dripper 7 flows out, enters in the water receiving measuring cylinder 8. In the first working mode, the specified time is set by the button 15, and the timing function liquid level control system starts timing when the flow valve 6 is opened. When the time reaches the specified time, the timing function liquid level control system will close the flow valve 6, The liquid level sensor 12 transmits the liquid level signal at this time to the control system, and the control system records it and displays it on the display screen 14, thereby completing the filtered water volume measured within the specified time; in the second working mode , set the liquid level signal value through the button 15, open the flow valve 6 and at the same time the timing liquid level control system starts timing, when the liquid level measured by the liquid level sensor 12 is the same as the set liquid level signal value, the timing liquid level control system Then the valve 6 is closed, and the closing time is recorded and displayed on the display screen 14, so as to determine the time required for the specified water filtration volume. the
