Application:
The meter is used for precise dosing system which need to adjust the PH/ORP value accurately, the application fields including: Industry process, waste water treatment, Water Reuse Systems, Circuit Board waste water , electroplating waste water treatment, medical industry and etc. It can meet the requirements of backlash and dead area control in chemical, medicine reaction and neutralization process. And it is also meet the requirements of intelligent configuration transmitting control systems in PID close loop adjustment, difference value control, switch control, pulse frequency / duty cycle control, current transmitting, dosing tank level management.
Features:
Electronic chemical inline measurement +sensor + PLC+Professional software=system integration
Multi channels ( pH or ORP , pH+ORP,TEMP) sensors for inline measurement.
Dynamic PID adjustment, PWM pulse, controlling metering pump for accurate adjustment.
Professional solutions for electroplating process waste water treatment. Double channels ORP different value dynamic control
Driving solutions for various dosing pumps, Static switch, and PWM pulse selection.
Dosing tank low level alarm avoids dosing error
Multi-function sampling flow device needs only a little sample.
