2. What flowmeter is good for measuring natural gas?
It is recommended to use vortex flowmeter for natural gas measurement, which has excellent comprehensive performance and wide applicability. The following analysis is conducted from three aspects: technical principles, product advantages, and selection points:
1. Technical principles and applicability. The vortex flowmeter works based on the Karman vortex principle: when the fluid passes around a non streamlined cylinder, the instability of the boundary layer causes the formation of regular vortex columns alternately on both sides of the cylinder. By using piezoelectric crystals to detect vortex frequency, fluid flow rate can be indirectly measured. This principle is suitable for measuring clean gases such as natural gas, especially for working conditions with high Reynolds numbers (such as natural gas pipeline transportation), and can stably capture vortex signals and convert them into flow data.

Secondly, the core advantage of the product is high precision and wide range measurement accuracy of ± 1%, with a range ratio of over 10:1, covering the measurement needs of natural gas from low flow to high flow. Support measurement of working condition volume flow rate or standard volume flow rate (integrated intelligent temperature and pressure compensation), adapting to different pressure and temperature conditions.
