Principle and characteristics of gas Roots flowmeter

Integrating high-precision temperature, pressure, flow sensors and intelligent volume correction, the high-precision gas flow meter can detect the temperature, pressure and flow of the measured gas, and perform passive flow tracking compensation and expansion factor correction operations. 

Adopting advanced microcomputer technology and high-performance integrated chips, the whole machine is powerful and has excellent performance. The circuit adopts surface design technology, with strong structure coordination, strong anti-interference ability and high reliability. The pressure sensor, temperature sensor and flow sensor are all built-in, making the structure more discrete. 

Adopting advanced micro-power high-tech technology, the whole machine has low power consumption, which can be powered by the built-in battery for a long time, and can also be powered by an external power supply. According to the flow frequency signal, the instrument coefficient can be divided into six sections for active linear correction, thereby improving the application accuracy of the instrument. It has self-diagnosis and alarm compliance, high reliability, and uses LCD display, which is clear and intuitive, and easy to read.
