1. Product advantages
1. High-precision measurement
Applicable to gas (such as natural gas, coal gas, air) and liquid (such as oil, chemical liquid), with an accuracy of ±0.5% to ±1%, and some models can reach ±0.2%.
Not affected by changes in fluid density and viscosity, strong stability.
2. Wide range ratio
The range ratio is usually 1:10 to 1:100, suitable for large and small flow conditions.
3. No straight pipe section requirements
Compared with turbine and orifice flowmeters, Roots flowmeters have low requirements for installation of straight pipe sections and save space.
4. High pressure resistance and corrosion resistance
Made of cast steel, stainless steel and other materials, suitable for high pressure (up to 10MPa or more) and corrosive media.
5. Low starting flow
The starting flow is small, especially suitable for small flow measurement (such as gas micro-leak detection).
6. Good long-term stability
The mechanical structure is simple, with little wear, and it can still maintain high accuracy after long-term use.
7. Multiple output modes
Supports pulse signal, 4-20mA, RS485 (Modbus) and other outputs, which are convenient for remote monitoring and automatic control.
8. Suitable for trade settlement
Widely used in trade measurement in natural gas, liquefied gas, petrochemical and other industries, in line with international standards (such as OIML R137).
