Thanks to their robust design the gear flow meters of the series ZHM ST are suited for applications with lubrication and non lubrication liquids as well as for filled viscous and abrasive media. The parts of products of this series are manufactured exclusively of high-grade stainless steel, so these products are also suited for applications with corrosive materials. Various design sizes of the flowmeters of the series ZHM KL allow a wide range of applications in such areas as consumption measuring, monitoring, mixing and dosing. Optimal measurement accuracy as well as good dynamic characteristics are guaranteed thanks to very high-quality bearings made of sintered carbides (hard metal). Short reaction times and exact dosing and flow measuring can be therefore performed in different areas of applications.
