L Rotameters / 1/8”to 1/4”

L series rotameters are rugged PTFE-PFA flow meters for low to medium flow measurements of highly corrosive or ultra-pure liquids. Wetted inert components are surrounded by structurally rigid materials representing a unique combination of a rugged mechanically rigid frame and chemically inert wetted parts. Each meter is provided with a safety shield for protection of personnel.

Flow meters are supplied with or without built-in needle valves and they are panel mountable.
