Operating Temperature
The SEWER-MAGTM is an insertable full bore electromagnetic flow
meter sensor. It ensures extremely accurate flow determination
even under difficult flow conditions. The Sewer-Mag is usually
temporarily installed in sewer networks to verify or calibrate
existing flow meters.
The inflatable flow-through plug forces the water through the
measuring tube, which is maintained full with an especially
designed outlet elbow. The flow-through plug creates a straight
section (3x the pipe diameter) upstream the measuring point and
the outlet has a length of 2x the pipe diameter downstream.
The SEWER-MAGTM can be combined with 2 different electronics:
ML210 (AC or DC powered)
Mobile-Mag (DC or battery powered)

0°C to +80°C

Storage Temperature

-30°C to +80°C

Protection rate

IP68 (standing immersion with
1,5 m of head water)

How to select the correct dimensions of the SEWER-MAGTM?
The dimensions of the SEWER-MAGTM depend on the flow
range to be calibrated or measured and of the sewer pipe
dimensions. When the system is smaller, it is less expensive
and easier to install due to smaller overall dimensions and
less weight.
