Model T flow meters incorporate the principles of traditional variable area flow technology. These rugged PTFE-Glass flow meters offer solutions to low to medium flow range measurements of highly corrosive or ultra-pure liquids and gases.Wetted inert components are surrounded by structurally rigid anodized aluminum. The resultant design represents a unique combination of a rugged mechanically rigid frame and chemically inert wetted parts.For additional protection of personnel each meter is supplied with a thick protective magnifying safety shield.
