Field of application
The wafer flowmeter Promag D is designed for all basic water applications where space is at a minimum. Its innovative housing construction enables a customized and fast centering as well as a cost-optimized installation. Promag D 400 saves time and costs thanks to the broad functionality of its water- and wastewater-optimized transmitter. In addition, Heartbeat Technology ensures measurement reliability and compliant verification.
The bidirectional measuring principle is virtually independent of pressure, density, temperature and viscosity.
For basic water applications; optimized for limited space and plastic pipe installations
Device properties
Short installation length and low weight
Integrated ground disks made of stainless steel
International drinking water approvals
Transmitter housing made of durable polycarbonate or aluminium
WLAN access
Integrated data logger: measured values monitoring
