Roots flow meter for gas

Applications:

Gas roots flow meter has a history of over one hundred years as volumetric measuring instrument featured with high accuracy, wide measuring range, small volume, light weight, easy installation and maintenance, reliable use and durable service life etc. The flow meter is widely used in the flow measurement of natural gas, coal gas, inert gas, and air etc. And it is the ideal flow measuring device of departments as urban combustion gas, oil field, chemical industry and scientific research etc.

Features:

- rotor consistency, symmetry good, to ensure a good repeatability.

-In case of a large velocity change is also able to maintain an accurate measurement.

-starting flow is small, pressure loss is small, compared with a wide range suitable for micro-flow measurements.

-special treatment to make a more reliable flow meter operation, longer life.

-Aluminium alloy material, small size, light weight, installation and maintenance more convenient.

-advanced computer technology and high-performance microcontroller, so that machine more powerful and better performance.

-Intelligent design can be integrated dynamically detect medium temperature and pressure, and compression factor for automatic compensation and amendments to the standard instantaneous direct display of gas flow and the standard volume of the total volume.

-using RS485, RS232C, MODBUS protocol with dedicated MODEM supporting, through the telephone network to build automated meter reading management system, high degree of automation.
