The Series Z-6000/Z-6500 In-line Flow Monitor

Unrestricted mounting, dual scales, optional switch output, from 1/2" - 2" Pipe

The Series Z-6000/Z-6500 In-line Flow Monitor are spring-loaded variable-area flowmeters. They can be installed and used in any direction. These instruments measure flow rate by balancing the drag force of a spring with the force exerted on a float, which is propelled by fluid flow. When fluid passes through a tapered tube, the float experiences a thrust due to the fluid's kinetic energy, while the spring provides an opposing resistance. As the flow rate increases, the float moves further, expanding the annular passage area. Ultimately, the float stabilizes at a position where the spring force balances the hydrodynamic force, directly indicating the flow rate via its position.
