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.
