Contrec 515 Series with CB02 application is a secure blending controller measuring the volume flow in a main and process line using frequency flow inputs. The main and process flows are used to determine the net volume flow. The operator can view the ratio of totals as well as the ratio of flowrates.
The control of the process flow is via a digital control valve. The flowrate deadband and control responsiveness can be adjusted to reduce wear on valves. 515-CB02 can be set to prompt for a valid ID-Tag before delivery can commence, while the valid ID-Tag also sets the pre-programmed target ratio % and is stored as a part of the logged transaction record.
