GLCK-100 Liquid Level/Flow Measurement and Control Experimental Equipment

I、Equipment Introduction

The important structural features of this liquid level/flow measurement and control experimental equipment are small, compact, beautiful and safe. The equipment can form a closed-loop PID adjustment liquid level control system or a PID adjustment flow control system for flow and liquid level (single volume) (double volume), and communicate with the host computer through the communication port of the intelligent regulator. The control parameters can be set in the intelligent control instrument and the host computer. The host computer software uses MCGS industrial control configuration software to realize online detection, control, parameter modification, data storage and analysis, real-time curve and historical curve display and printing. This equipment has multiple safety protections and provides IEC standard signals and related test points for single-chip microcomputer access for programming experiments.

This liquid level/flow measurement and control experimental equipment uses industrial-grade sensors and IEC standard signal outputs. It is suitable for measurement and control, automation, computer, electromechanical control, information engineering, mechatronics and other majors. This equipment is placed on the experimental table and can operate experiments independently or connect to the host computer.
