Quantitative control flowmeterAfter receiving the flow signal from the flowmeter, the quantitative controller accumulates the flow rate internally and sets the required quantitative control value internally. When the cumulative value displayed by the quantitative controller reaches the set quantitative control value, the quantitative controller outputs a switch signal. At this time, the switch signal is used to control the flow interruption equipment (solenoid valve) installed on the pipeline through the matching relay or contactor, thereby achieving quantitative control.
XSN intelligent quantitative controller is used in conjunction with sensors for vortex street and turbine pulse signals for flow quantitative control. The error is less than 0.2% F.S, and it has calibration and digital filtering functions, which can help reduce sensor errors and effectively improve the measurement and control accuracy of the system. It is suitable for flow sensors with pulse output
3-point switch input, used for starting, restoring, and resetting accumulated values each time
3-point control output, used for valve control with a control cycle of 0.02 seconds
The 7-segment line calculation function can reduce the nonlinear error of the flow sensor. The instantaneous flow can be measured in hours or minutes
