JC 050 series metal tube rotameter is a kind of measuring meter in 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 convenience for 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.

JC050 series metal tube rotameter 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-wire 4-20mA current output, etc. 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 as petrochemical, steel, and iron, electric power, metallurgy, light industry, food, pharmacy, and water processing.

Working Principle -metal tube rotameter




1. Firm work, little maintenance and long life

2.Low requirements to straight pipe part

3.Broader ratio of flow rate 10:1

4.Two-wire LCD indicator; instant/accumulated display of flow rate are available; backlight option.

5. Single axis and sensitive display

6.Rotation of non-contact magnetic coupling

7.Can be applied to hazardous occasions such as flammable and explosive ones

8.All-metal structure, fit for high temperature, high pressure, and mediums with strong erosion.

9.  power supply such as two-wire system, battery, alternating current option

10. Multi-parameters calibration function

11.  Function of date recovery, date copy, and power-off protection
