Frequently Asked Questions

What is a thermal gas mass flow meter?

It measures gas flow based on thermal dispersion. It directly measures mass flow without needing pressure or temperature correction, ideal for single or fixed-ratio mixed gases.

Can your flow meters handle high temperatures?

Yes, many of our meters, especially vortex and precession types, are designed for high-temperature steam and industrial processes.

Do you offer customization?

Yes, we provide tailored solutions for fuel counters, circuit designs, and communication protocols based on client requirements.

What output signals do your transmitters support?

Our smart transmitters support 4–20mA analog output and RS485 digital communication for seamless integration.
