Flow Meter Installation

Wafer Style Meter Installation

Install the Dura Mag between two flanged end pipes. 

Hardware and gaskets are provided, but customers must 

supply the flanged pipe ends.

Remote Mount Installation

You will need to prepare the location where you will install the remote converter. The location cannot be further from the 

flow meter than the length of the 25’ cable. This must be planned in advance because the cable cannot be lengthened. 

Doing so will alter the calibration accuracy between the meter and the converter and void the warranty.
Install the flow meter as required. Mount the converter and connect the cable to the meter’s junction box and the 

converter’s external connection.

Flanged Meter Installation

Install the Dura Mag flow meter inline between two flanged end pipes. The flow meter may require grounding, depending 

on the environment they are being installed in. Refer to section 4 for a full description of grounding methods that are 

available.

Shown are customer’s 

pipe ends and flanges

IMPORTANT: The example shown above does not include grounding 

installation. Depending on your requirements, the meter will need to be 

grounded according to the methods shown in section 4.

The Dura Mag requires grounding to ensure proper functioning and accuracy. See section 4 for grounding 

instructions and methods.
