What is the flow control system?

What is the flow control system? In the system consisting of intelligent flow batch controllers, since the controller is specially designed for flow batch control, it has more functions. If there are some incomplete features, it can be negotiated with the manufacturer as a special order. Complements.
(1) System composition Figure 5.2 shows an example of a batch control system for the shipment of finished oil products. The flow rate is measured by the Coriolis mass flow meter, and the dedicated batch controller is used for logic control. The tanker carries out the material and selects the issue object through the switch. Product oil shipment batch control system
Since the flow converter is installed in front of the discharge valve, the back pressure can be guaranteed. However, if the shut-off valve is fully closed immediately when the discharge stop signal arrives, the original high-speed liquid will produce a "permanent hammer" effect, causing the instrument to be caused. In order to avoid this, the shut-off valve uses a two-stage valve.
The field display in the system is set to increase operational transparency, ie the analog output signal of the flow transmitter is sent to a digital totalizer located on the dock. The calculator integrates the simultaneous calculation and displays the total amount while the material is being sent, thus avoiding the black box operation and reassuring the customer.
The information in the controller is sent to the host computer through the communication port to realize automatic loading management, automatic billing, automatic report generation, and so on.
1 The composition of the system is relatively simple, just configure the controller and the system can be put into use.
2 Because the system also has an online calibration device, the Coriolis mass flow meter can be calibrated on-line regularly, so the accuracy of the delivery is more guaranteed.
3 The design of the system is dual-use and the addition of on-site total indications is based on actual needs and is of practical value.
