For the correct calculation of the flow rate make sure that;
After each change of the single-use flow tube, to check and enter the maximum flow (Qmax.) and the
k-factor of the new flow tube into the formula of the control system.
The k-factor is put in the control system correct and accurately (without typing an error, with 3 digits
after the decimal point) as printed on the flow tube label.
The tube diameter is entered in the control system (¼ - ⅜ - ½ - ¾ or 1", as printed on the label).
