Electromagnetic Flowmeter Endress+Hauser Proline Promag L 400
The versatile, weight-optimized Promag L is the preferred choice for all
standard applications in the water and wastewater industry. Due to its
unique lap-joint flange concept, the flowmeter guarantees flexible, easy
and economical installation. Promag L 400 saves time and costs thanks
to the broad functionality of its water- and wastewater-optimized
transmitter. In addition, Heartbeat Technology ensures compliance and
process safety at all times.
