Rotameter Flow Meter
Rotameter flow meter, also known as the “metal tube rotameter”, is a measuring instrument commonly used in the industrial automation process management to measure the variable area flow. Being featured with characteristics of small size, wide application range, convenient usage, etc., it is designed for measuring the flows of liquids, gases and steam, especially applicable for measurement of low flow speed and small flow rate.
It has the following distinguishing advantages:
- Designed for measurement of small caliber and low-speed medium
- With reliable performance, few maintenance and long service life
- Small volume, large flow range, convenient operation
- Indicator of the intelligent flowmeter which have intellectual Property
- Reliable operation, small maintenance work loads and long life low straight pipe condition required and wide twrn-down10:1
- Whole metal structure, suitable for high temperature, high pressure and strongly corrosive media
- Can be used in flammable, explosive and dangerous situations
Key Feature
- Widely measure ratio: 10:1
- Dual-line display, instantaneous/ cumulative flow rates displayed at the field
- With a keyboard on the indictor for convenient operation and setting
- All in metal construction, designed for measuring corrosive medium of high temperature, high pressure and strong
- Non-contact magnetic coupling transmission
- Applicable for inflammable and explosive occasion
- Optional charging modes: DC power supply or battery power
- With the functions of data recovery, data backup and power failure protection
- Multiple parameters calibrating function
Application Range
Over the years, with its excellent property and reliability as well as preferable cost performance, the metal tube float flowmeter has been applied widely in a variety of industries, such as the petrochemical engineering, iron and steel, electric power, metallurgy, light industry, food, pharmacy, water treatment, etc
