Your benefits
- Precise sizing of the water meter according to the flow rates occurring in the system:
Improved efficiency
Applications
- Measurement of high, strongly fluctuating flow rates, e.g.:
• Commercial and industrial installations
• School and sports complexes
• Apartment blocks
• Hotels - Specified pipe sizing for fire-fighting water demand
Options
- Flood-proof GWFcoder® main and secondary registers (IP68) with IEC or M-Bus interface, 5 m cable and one interface each for an HRI pulse transmitter
- High-resolution pulse transmitter HRI-Mei
