China LL Series Roots Flow Meter:
Installed in the counter agency transmitter which became waist wheel flow meter with a transmitter. And display instrument or form a complete set of microcomputer system, which can realize remote transmission (quantitative, cumulative, instantaneous) automation measurement and control.
When liquid flows through measuring room, in the import and export form differential pressure flow meter, waist wheel driven in the differential rotation. At the same time through a pair of drive gear on the shaft fixed to the waist, to keep two waist round continuous rotation. As the waist wheel rotation, the liquid through a measuring room had been discharge flow meter. Each pair of flow of liquid volume is four times the size of the measuring room volume, by sealing coupling, retarding mechanism, will be passed to the after rotation frequency reduction counter, counter instructed liquid instantaneous flow and cumulative flow.
Installed in the counter agency transmitter which became waist wheel flow meter with a transmitter. And display instrument or form a complete set of microcomputer system, which can realize remote transmission (quantitative, cumulative, instantaneous) automation measurement and control.
