Clack Stainless Steel Inline Flow Meters

Clack Corporation produces stainless steel inline flow meters in 1.5", 2", and 3" sizes, featuring durable construction and high-accuracy turbine designs for commercial and industrial water treatment systems.

Material: Constructed with 316 stainless steel for superior resistance to rust and corrosion in harsh environments.
Finish: The body is electropolished, which further improves corrosion resistance and provides a bright finish.
Design: Utilizes a reliable and proven clipped turbine design for consistent performance.
Installation Flexibility: A built-in flow straightener design eliminates the need for minimum pipe lengths before and after the meter, simplifying installation.
Application: Suitable for a variety of applications, from residential to heavy industrial systems.
Compatibility: Designed to work with Clack control valves, providing an output signal (pulse) to the valve’s circuit board for volume tracking and regeneration control.
Cable Lengths: Available with either a 28-inch or a 15-foot cable for flexible installation.
