Description

The 515 AI01 application is designed to control the injection of additive chemicals with respect to the main flow. Tailored for volumetric frequency flowmeters it will operate with positive displacement dosing pumps controlling the dosing rate via either an output pulse or 4-20mA signal. The instrument will calculate a Target Stroke Rate and the intervals of the main volume at which a Stroke Output Pulse will be generated based on the dosing pump parameters and the process ratio set point, programmed in PPM (parts per million). The additive flow is monitored and measured along with the main flow to continuously calculate the overall Process Ratio and the Sample Ratio that provides a faster “real time” PPM value of the dosing chemical. There are flow and deviation exceptions, alarms and a permissive that can be used to help maintain control and integrity of an additive injection system.
