Summary
The standard LZ series metal pipe float flowmeters are composed of one measuring tube and on side indicator.The site indicator can be installed also with additional electric devices, suitable for liquid and gas measurement.
The flowmeter adopts to variable area measuring principle. The measuring device is composed of one taper measuring tube and floater. The floater can move freely up and down in the taper measuring pipe to change the flow area in the pipe.When the flow changes, the vertical position of the floater inside the measuring pipe changes correspondingly.Through magnetic transmitting system, the position of the floater is transmitted to the dial scale of the indicator to indicate the flow.
In M6,M8, M9 indicator, the follow-up magnet movement is transmitted directly
to the dial scale.In M7 indicator, when the follow-up magnet rotates, the needle
driven by the cam plate indicates linearly the flow.
