Digital Rotameter


1.Small volume
2. Borad measuring
3.Convenience for use
4. Measuring liquid ,gas and vapor flow


The series metal tube rotameter is a kind of measuring meter which the flow rate is changing along with the area and is widely used in the process control of industrial automation. It has the merit of little volume, broad measuring range and conveniencefor use. It can be used to measure liquid, gas and vapor flow especially fits for the flow rate measurement of low flow velocity and little flow rate.

The series metal tube rotameter also has local indication type and smart remote type with a pointer LCD displaying instantaneous/ accumulated flow rate, upper-limit and lower-limit alarm output, accumulative pulse output, batch control, standard two-wire4-20mA current output, ect. Additionally, this instrument employs advanced microprocessing central chip and high-quality industrialized components of Motorola corporation to ensure the good performances of flowmeters in all applicational fields.

For many years metal tube rotameter are well received by many industries such aspetrochemical, steel and iron, electric power, metallurgy, light industry, food, pharmacy and water processing.
