Product Introduction
The AI-FK explosion-proof thermal gas mass flow meter is an explosion-proof thermal gas flow sensor designed and developed using an advanced microelectromechanical system (MEMS) flow sensing chip. This explosion-proof flow meter features high accuracy, high sensitivity, and strong anti-interference capabilities, making it suitable for measuring and controlling various small-flow-rate clean gases. Designed according to explosion-proof standards, this flow meter is suitable for various harsh environments, offering low cost, easy installation, and no need for temperature and pressure compensation. It can replace traditional volumetric or differential pressure flow meters.
