Product Details

Overview of LKJ type metal tube float flowmeter for distilled water:

This flowmeter adopts the principle of variable area measurement by Chengfeng Instrument. The measuring components consist of a conical measuring tube and a float. The float can freely move up and down in the conical measuring tube, changing the flow area in the pipeline. As the flow rate changes, the vertical position of the float in the measuring tube also changes accordingly. The position of the float is transmitted to the dial of the indicator through a steel pipe magnetic transmission system, indicating the size of the flow value.
In M6, M8, M9 indicators, the rotation of the follower magnet is directly transmitted to the dial; In the M7 indicator, the rotation of the follower magnet causes the pointer to linearly indicate the magnitude of the flow rate value through a cam plate.
