Metal Tube Rotameter


A float moves up in vertical measuring table according to fluid dynamics acting for float flow meter LZ¡õ The float displacement is in proportion to flow rate between float and orifice. Local display is a pointer from .It is able to have standard signal with rotary angle for electric signal or pneumatic transmitter for pneumatic signal. So that it is used with unit-complied meter.

Serial LZ flow meter have advanced characteristic, such as simple construction, easy maintains, Liner Scale and reliable operating. And it could measure flow rate for liquids and gases.

The flow meter with upper and lower limit alarms could use in the control system..

2. functional

The series LZ flow meter consists essentially of two basic parts: Transducer--measure tube and floater; Signal transmitter_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.

3. Special features

 Rugged all-metal design

 Easy stocking of parts thanks to modular concept

 Complete interchangeability of all components and assemblies

 Linear display

 Adjustable to any fluid through replaceable cam plate

 Shot-stroke design/parts do not project beyond the flanges,no matter what position the float is in

 Electrical or pneumatic remote data transmission system

 Limit switches can be installed
