Glass tapered tube flow meter "GTV series"

Glass tapered tube flow meter suitable for measuring the flow rate of corrosive liquids and gases.

The "GTV Series" is designed to be mounted directly and vertically on piping, measuring the instantaneous flow of liquids and gases within the piping. The flange material is made of rigid polyvinyl chloride (PVC-U), making it suitable for measuring the flow of corrosive liquids and gases. The flow scale on the surface of the glass tapered tube is engraved in a concave shape and treated with a reddish color, enhancing visibility. Additionally, we also offer the acrylic tapered tube flow meter "ATV Series." 【Features】 ■ Ideal for measuring the flow of corrosive liquids and gases ■ Flange material made of rigid polyvinyl chloride (PVC-U) ■ High visibility flow scale on the surface of the glass tapered tube ■ Acrylic tapered tube flow meter "ATV Series" also available *For more details, please refer to the PDF document or feel free to contact us.
