CALCULATING UP-DOWN CHEMICAL AND DOSING PUMP RATE

Note

As the inlet and outlet pressure does not seem to affect the dosing rate. Below calculated is for reference and need to calibrate for 1 hr at least. If the pump is running continuously, Stop time will be 0 minute

Data Input
Result
1 PUMP  SELECTION AND SET UP % DOSING
Chemical q'ty per hr kg / hr
Density kg / lit
→Volume liter / hr 0.00 = 0 ml / min
Total minutes ON/1HR minutes / hr

→Remain minutes OF minutes / hr 0.0

→Flow rate at On liter / hr 0.00 = 0 ml /min
→Min - Max Flow rate - ( 1.5 - 3X) liter /hr-giờ 0.00 Min 0.0 Max
→Choose flow rate liter /hr

→% Set up % 0.0

2 UP / DOWN % DOSING RATE WITH UP / DOWN % CHEMICAL
Up or Down (-) chemical %

→Chemical after adjusted kg/hr 0.00 = 0.00 Liter /hr
→%  new set up % 0

→%  pump changed % 0
3 DILUTE CHEMICAL WITH WATER
Chemical to dilute kg
Water inquired liter
Diluted chemical volume to check density (20 - 50 Liter) liter

Weigh of chemical per above volume kg
→New Density kg/lit 0.00

Re-set up % pump as Above calculation
