ZHM CT Series

Gear Flow Meters in Cartridge Design for paint applications, optimized flushing and weight design

The ZHM series in the patented cartridge construction (ZHM CT) was developed primarily for coating applications. Structural characteristics such as flat seals and free-standing axes ensure optimum flushing.

Cartridge construction drastically reduces the weight compared to the standard version, and permits mounting directly in the spraying head on the robot arm without restricting the robot’s dynamic behavior. The flowmeters have a very high resolution that supports extremely precise flow rate measurement across a very broad measuring range.

Since they are easy to flush, colors can be changed quickly without interfering with subsequent coating due to color residues in the measuring cell.
