The ZHM CT gear flow meter series (cartridge design) are flow meters which are mainly used in water- and solvent-based paints, as well as fillers and base coats. Also suitable for cavity waxes and for abrasive and filled media in the automotive sector. Short response times, accurate dosage, and flow rate measurements support applications in coating lines and preservation and other coating systems.
Only high-grade steels that even withstand corrosive liquids are used in the production of gear flow meters. Combined with the use of tungsten carbide bearings, the ZHM CT guarantees optimum measurement accuracy and a long service life under even the toughest application conditions.
The cartridge construction reduces the weight by another 75% compared to the standard version. The space-saving design with reduced weight permits installation in fully automated coating lines as well as mounting on robot arms in the process without limiting the dynamic behavior. Thanks to the innovative, dead space optimized design, color changes and flushing cycles can be realized in less time.
Fiber optics pulse amplifiers that enable interference-free signal transmission in areas of powerful electrical fields make applications possible in electrostatic coating lines (ESTA lines). For applications in hazardous areas, we offer intrinsically safe sensors and amplifiers with Ex protection in accordance with ATEX, IECEx, CSA and other standards. Additional certifications such as EAC (TR-CU) are available.
