Metal rotameter is suitable for small diameter and low velocity medium flow measurement. Suitable for measuring liquid, gas, even for high temperature, high pressure and strong corrosive medium.Include direct Pointers instruction type,ordinary LCD display type and explosion-proof type.
Rotameter Flow Meter, Rotameter, Rotary Gas, Liquid Flowmeter
can be used for measure volume flow of liquid or air, example air flow measuring, water flow test, diesel oil flow meter.
The metal rotary flowmeter consists essentially of three basic parts:
The metering tube
The tapered float
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.
Rugged all-metal design
Easy stocking of parts thanks to modular concept
Complete interchangeability of all components and assemblies
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
