The Series TVA All Fluoropolymer Flowmeters are ideal for high purity or corrosive
liquid applications. This series of owmeters features a 0 to 10 scale graduations
denoting a discrete ow rate.
FEATURES/BENEFITS
• Chemically inert wetted components yield long life even in corrosive liquid
applications
• Low installation costs with standard back process connections for easy panel
mounting
APPLICATIONS
• Chemical injectors
• Deionized water systems
