JC040 Vortex Natural Gas Flow Meter

JC-040 series smart precession whirlpool flowmeter uses new microprocessing
techn ology with strong function, wide flow range, simple maintenance and co
nvenient installation & use. It is widely used in industries such as petrol,
chemical, power, metallurgy and coal, etc.
BCST Natural Gas Flow Meter Feature
1. Built-in pressure, temperature and flow sensors with high safety, compact
structure and exquisite shape.
2. Local indication of temperature, pressure, instantaneous flow and
accumulative flow.
3. Use new signal processing amplifier and unique filtration technology,
effectively eliminate interfering signal generated by pressure fluctuation and
pipeline vibration, greatly improve anti-interference ability of flowmeter, and
make good stability of little flow.
4. Special time indication and real-time data storage function; under no
circumstance will the internal data be missing and will be stored forever.
5. Password protection
6. Low power consumption, internal battery supply, no need for external power
supply.
