Proline Promag L 400 Electromagnetic flowmeter
The flowmeter with integrated web server and a weight-optimized sensor
Product Overview
Promag L is the versatile standard sensor designed for the water industry with a lap-joint flange concept for flexible installation independent of the orientation of the pipe flange pitch diameter. Combined with Proline 400, the transmitter for optimized measurement of water and wastewater, Promag L 400 will be the preferred solution for all standard applications in this industry. Promag L 400 also offers an integrated web server. Integrated verification with Heartbeat Technology.
Benefits
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
Safe operation – no need to open the device due to display with touch control, background lighting
Time-saving local operation without additional software and hardware – integrated web server
Integrated verification – Heartbeat Technology™
Field of application
The measuring principle is virtually independent of pressure, density, temperature and viscosity
Fully suitable for standard applications in the water and wastewater industry.
Device properties
Up to 30% less sensor weight
Nominal diameter: DN 25 to 2400 (1 to 90")
Maximum reduced installation length to DVGW/ISO
Transmitter housing made of durable polycarbonate or aluminium
Same housing concept for compact/remote version
Integrated data logger: measured values monitoring
