Product Description
What is Metal Tube Rotameter?
Metal tube rotameter, characterized by high strength, safety, and durability, is designed to measure the flow of such medium as liquid, gas, and vapor etc. It is especially suitable for measuring the corrosive and turbid liquid as a result of its fine characteristics of high pressure and temperature resistance. Metal tube rotameter is able to not only ensure high measurement accuracy but also enhance safety and dependability. Thanks to its nicely unique appearance design, it has the finest explosion proof performance.
The rotameter adopts variable area measuring principle. The measuring device is composed of one taper measuring pipe and floater. The floater can move freely up and down in the taper measuring pipe to change the flow area in the pipe. When the flow changes, the vertical position of the floater inside the measuring pipe changes correspondingly. Through magnetic transmitting system, the position of the floater is transmitted to the dial scale of the indicator to indicate the flow.
Rotameter uses magnetic sensor and chip process technology, which allows the LCD to express instantaneous flow, accumulated flow, and percentage flow, and also provides twowire current signals output 4~20mA, compatible with HART communication protocol. Equipped with the indicator and alarm switch on the setpoint, metal tube rotameter gives high precession indicating and alarm signals output.
Features of Metal Tube Rotameter
·         All metal construction, strong and stable.
·         Short stroke, compact structure.
·         Low pressure loss design.
·         New style magnetic coupling structure ensures that the signal transmission is more stable.
·         Magnetic filter can be added as customer requirements.
·         Thermal insulation or tracing heat jacket.
·         Used in the gas and liquid measurement in all industries. The measurement parts can adopt different materials to be suitable for different media.
·         Suitable for harsh environment and seriously corrosion media. Having good heat resistance and pressure resistance.
·         Intelligent dual-line LCD display, on site instant/cumulative flow display and back light as options.
·         Two-wire system, battery, alternating current can be chosen to supply the power.
·         With data recovery, data backup and power fail protection functions.
