| 主要特点 |
The flowmeter with a weight‐optimized sensor and highly cost‐effectiveness. Fully suitable for standard applications in the water and wastewater industry. |
| 特点 |
Reduced installation costs – flexible mounting by one‐of‐a‐kind lap‐joint flange concept (DN <350/14"). Energy‐saving flow measurement – no pressure loss due to cross‐section constriction. Maintenance‐free – no moving parts. Up to 30 % less sensor weight. Nominal diameter: DN 25 to 2400 (1 to 90"). |
| Transmitter features |
Cost‐effective – designed for easy applications and direct integration. Safe operation – display provides easy readable process information. Fully industry compliant – IEC/EN/NAMUR. 2‐line display with push buttons. Device in compact or remote version. |
