Natural gas flowmeter is widely used in petroleum

Natural gas flowmeter, widely used in petroleum, chemical, electric power, metallurgy, urban gas supply and other industries to measure various gas flow, is currently the oil field and urban natural gas transmission and distribution measurement and trade measurement of the preferred product.

Main advantages of natural gas flowmeter:

1, natural gas flowmeter without mechanical movable parts, corrosion resistant, stable and reliable, long life, long-term operation without special maintenance;

2. Natural gas flowmeter realizes mechatronics, and daily metering process does not need manual operation;

3. The process installation conditions of natural gas flowmeter are not harsh, and the upper and lower straight pipe sections of the meter can be greatly shortened compared with orifice and vortex street flowmeters;

4. The measurement accuracy of the natural gas flowmeter system can meet the current trade measurement requirements (≤1.5%);

5. The measuring range of natural gas flowmeter is wide (qmax/qmin=15 ~ 20), and it can work effectively in some small flow areas that cannot be penetrated by orifice plate and vortex street flowmeter;

6. Small size, light weight, convenient off-line calibration;

7. The measurement signal can be displayed locally or transmitted far as needed;

8. There is no need for professional training for instrument management personnel, and measurement parameters such as flow, pressure and temperature can be read directly from the meter head without conversion;

9. You only need to change the parameters of the battery (micro-power consumption) and the tested medium regularly.

10. Large pressure loss of natural gas flowmeter;

When the flow medium is gas, the pressure loss is about 3 ~ 4 times of that of vortex flowmeter.
