Product Description

Metal tube rotameter is a kind of flowmeter which is suitable for measuring flow of liquid and gas through floater movement inside metal tube. Data of flow can be read from dial scale thanks to magnetic coupling to act on signal transmitter. Output of electrical signal is 4-20mA.
Standard LZ series metal pipe float flowmeters are composed of one measuring pipe and on side indicator. The site indicator can be installed also with additional electric devices, suitable for liquid and gas measurement.
The flowmeter 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.
In M6, M8, M9 indicator, the follow-up magnet movement is transmitted directly to the dial scale. In M7 indicator, when the follow-up magnet rotates, the needle driven by the cam plate indicates linearly the flow.

1). All metal construction, strong and stable.
2). Short stroke, compact structure.
3). Low pressure loss design.
4). New style magnetic coupling structure ensures that the signal transmission is more stable.
5). Magnetic filter can be added as customer requirements.
6). Thermal insulation or tracing heat jacket.
7). Used in the gas and liquid measurement in all industries. The measurment parts can adopt different Materials to be suitable for different medias.
8). Suitable for harsh environment and seriously corrosion media. Having good heat resistance And pressure resistance.
9). Intelligent dual-line LCD display, on site instant/ umulative flow display and back light as Options.
10). Two-wire system, battery, alternating current can be choosed to supply the power.
11). With data recovery, data backup and powerfail protection functions.

The rotameter can be used in any harsh working environment due to its shatter-proof, pressureproof, temperature-resistant and corrosion-resistant characteristics.
