Recommended domestic brand flowmeters

The original poster mentioned conditions such as natural gas and fuel; indeed, ultrasonic and mass flow meters are both common solutions in such cases. I have come into contact with some domestic brands in the field of gas metering, and I’ll mention a few for reference: Ultrasonic flowmeters – brands such as Tianxin Instruments, Shenzhen Wanxun, and Beijing AVIC are widely used in the gas industry. These domestic brands offer a better cost-performance ratio compared to imported ones; however, when dealing with low-temperature or highly viscous fluids, it’s important to choose the right model accordingly. Mass flow meters: Emerson has joint ventures in China (such as Shanghai MicroPort), and domestic alternatives of the Coriolis type include Xi’an Dongfeng, etc.; these can be considered if the accuracy requirements are not extremely high. However, fluid properties (such as the presence of impurities or the gas-liquid two-phase state) can affect the measurements; it is recommended to confirm the operating conditions with the manufacturer. No matter which brand you choose, be sure to verify the explosion protection rating (natural gas and fuel are flammable and explosive) as well as the temperature/pressure range of the medium; it is advisable to ask the manufacturer for actual application examples or third-party certification documents. If a specific model comparison is needed, you can provide more details such as the pipe diameter, flow rate range, and whether trade settlement is required; we’ll help you make a decision together
