Flow Meters(LZ Metal Tube Float Type )

Date: 18 Jun 2009
Philosophy of Measurement:
LZ metal tube float type flow meter is a variable area flow meter. In the vertical measuring tube of the meter, the float moves upwards with liquid. When the lift and the gravity achieve balance at a certain position, the circulating annular space area between the float and the orifice plate keeps stable. A certain height of the float stands for a certain flow. The movement of the float will be displayed on the external indicator in the mode of magnetic coupling, with the indicating needle following the float. See Picture 1
The electrical remote transmission type has the flow rate accurately converted into standard signals of 0~10mA or 4~20mA through the angular displacement sensor and the transmitter circuit. 
Technical parameters:
Note:
Water: 20℃; atmosphere: 0.1013Mpa, 20℃; for special flow, custom design is available. DN150, Max. water flow 180m3/h, max. air flow 4500m3/h  
Structure and Dimension:
Structure:
A meter contains a measuring tube and a sensing indicator.
The measuring tube, with the parts in 1-7 and 10-11 of Picture 4, mainly ensures the accurate connection among the flow and the float. The movement of the float will be displayed on the external indicator in the mode of magnetic coupling, with the indicating needle following the float. And the flow rate is accurately converted into standard signals output of 0-10mA or 4-20mA through the angular displacement sensor and the transmitter circuit.
In the indicator there is one or two limit switches (K1 and K2). When the flow reaches the limit, the alarm signal is output. Before delivery, the flow limit has been set according to customer requirement. The limit switch and transistor amplifier (WE77/EX1.2) shall be specially ordered
