General

LZDZ Series Auto Batch Control Flow Meter is designed by our company for liquids control and precise measurement (hereafter we call LZDZ). LZDZ has the feature of compact structure, easy operation and stable performance. According to the preset flow value, LZDZ can control the process flow automatically and measure it precisely. In loading/unloading system, LZDZ can detect many signals such as electrostatic grounding, high level alarm and then operate automatically and safely. Through remote communication, LZDZ can also compose the Collecting- Distributing Quantitative Filling Control System with upper computer for rationing oil, which includes the functions of monitor, query and printing.
