Metal Tube Rotameter
FOUNDATION Field Device
Metal tube rotameter adopts variable area measure principle. It can measure both liquid and gas in test tube.
The RF series metal tube rotameter take advantages of high-tech. It has such features as stable structure,
wide adaptable temperature, high accuracy, cheap price and wide adaptable range.
◆Measure low flow range liquid and gas
◆Continuing flow measure and automatic control
◆For the medium which need readjust density, temperature, pressure
Merit of metal tube rotameter
Double indicator system:
The intelligent type of RFC series metal tube rotameter adopts the principle of magnetic coupling system.
Mechanical indicator can indicate flowrate，at the same time, the sensing magnet steel was moved , that
caused magnetic signal transfer to digital signal through conversion system. Digital signal can be displayed
on LCD screen for both flowrate and tantalizer. For the sake of double indicator system, stability of
flowmeter has been improved a lot. If digital parts meet failure, mechanical parts can work as well and
indicate correct flowrate.
Magnetic coupling system and magnetic signal separation
Independent magnetic coupling system is adopted for intelligent RFC series metal tube rotameter. Signals
of its transmission part come from special sensing magnetic steels. The advantages of such structure are
that it will not be affected by temperature of media and ferromagnetic particles in measurement. In
addition, it will not be affected by the size of diameter. Fixed distance is kept between sensing magnetic
steels and the magnetic resistance transducer, so it can be ensured that every instrument with different
diameter can have enough magnetic signals and high resolution can be brought, which can reach 1. At the
same time, it can bring high precision.
Double-line LCD display
The intelligent type of metal tube rotameter adopts double-line LCD display. Flowrate and totalizer can be
displayed simultaneity. The flow range of flowrate is 0.0001~99999. Flow range of totalizer is
0~99999999. It will reset automatically and the decimal points can be selected randomly. In addition, wide
temperature liquid crystal is adopted for the liquid crystal screen.
Software can adapt HART communication.
For the calibration system, the flowmeter adopts 11 points calibration, which can ensure accuracy of
flowmeter. In addition, HART communication pattern can be optional for selection.
