일반적인 설명

The Computer Controlled Process Control System (with speed controller), "UCPCV", consist of two dual tanks placed at different heights and two pumps that transport the water between them. The flow impelled by each pump can be adjusted using a flowmeter and a manual valve.

The system is controlled through a frequency inverter that regulates the speed of one of the pumps. In addition, it is included a line of on/off regulation valves, composed by three solenoid valves with different CV and several manual valves, to introduce disturbances in the system and to drain the upper tank.

The ,UCPCV, system can be used to control the flow, the level, the temperature, the pressure the pH, the conductivity and the total dissolved solids (TDS). For that purpose, it is needed to acquire the corresponding set, with the characteristics sensors and actuators of each control system.

The ,UCPCV, system includes the following elements:

• UCPCV-UB. Base Unit.

The ,UCPCV, system requires at least one of the following elements:

• UCPCV-T. Set for Temperature Process Control.

• UCPCV-C. Set for Flow Process Control.

• UCPCV-N. Set for Level Process Control.

• UCPCV-PA. Set for Pressure Process Control.

• UCPCV-PH. Set for pH Process Control.

• UCPCV-CT. Set for Conductivity and TDS (Total Dissolved Solids) Process Control.
