Functional
The series LZ flow meter consists essentially of three basic parts:

The metering tube
The tapered float
The indicator.
The flow rate determines the position of the float, the meter float is in dynamic balance, when the difference between the weight of the float and the weight of the displaced fluid equals the upward pressure resulting from the fluid velocity through the meter. The annular area between the tapered float and the tube increases until the upward and downward forces are in dynamic balance.
Since the position of the float in the metering tube can not be seen, an indicator is required, this indicator employs a magnetic coupling where a magnet follows the position of the float. The float encase an Alnico-transmitting magnet with two follower magnets arranged in parallel on the indicator shaft.
