GA-501  is a glass tube area flow meter, good for using when there is not enough space for installing, works generally in the same principle as of GA-10 Series.

This is designed to be suitable for large diameters rather than small diameters and specially designed to minimize damage of the transparent tube due to pressure change.

When manufacturing, we process the piping connection ourselves to freely decide on the direction of fluid inflow and outflow for applying to various piping arrangements. And we can decide on the varied materials of not only the body but the float inside the product and tapered tube for applying to most of fluids (liquids and gases).​
