Positive displacement flowmeters determine total flow by dividing the medium into chambers of fixed volume and counting how many times these chambers fill and empty. Because measurement is based directly on volume, they provide high accuracy at low flow rates and with viscous media.
Selection parameters
| Nominal diameter (DN) | According to line size |
| الوسط | Viscous liquid, fuel, oil or chemical |
| Viscosity range | Determined by the medium |
| Working pressure | According to line pressure class |
| Working temperature | According to medium temperature |
| الخرج | Mechanical register or pulse/analogue output |
Measuring range, accuracy class and body material vary with the medium and are therefore determined on a project basis. Contact us to select the right model for your line.
