Gear Flowmeters for Chemical Injection (ZHM-MK)
- Measuring range:
0.002 to 75 l/m - Viscosity:
0.8…30 mm²/s - Linearity:
±1.5 % of actual flow (viscosity ≥ 5 mm²/s , ±2.5 % of actual flow (viscosity ≥ 5 mm²/s for ZHM 01/3) - Pressure:
max. 420 bar
The ZHM MK gear flow meter (ball bearing design) are flow meters which are mainly used in lubrication and low-viscous liquids. Therefore they are used especially for the fuel consumption measurement and the dosing of low viscous media. Only high-grade steels that even withstand corrosive liquids are used in the production of gear flow meters.
Combined with the use of high-quality precision ball bearings, the ZHM MK guarantees optimum measurement accuracy and a long service life under even the toughest application conditions. The ball bearing facilitates a very low starting torque of the measuring element. This way even the lowest flow rates can be accurately measured.
