GF Signet 2552 Metal Magmeter Flow Sensor - Manual (Page 5)

5 2552 Magmeter
1. The height from the magmeter electrodes to the alignment rod is:
-2 Versions: 276.3 mm ( 10.88 in. )
-3 Versions: 419.0 mm ( 16.50 in. )
2. Subtract the wall thickness of the pipe:
- Wall Thickness: -_____ mm ( ______ in.)
3. Subtract 10% of the pipe inside diameter:
- 10% of pipe id: -_____ mm ( ______ in.)
4. The result is the H-dimension. Record the result here for reference at the installation site:
= H dimension: =_____ mm ( ______ in.)

4.3 Preparing for Installation
The alignment of the electrodes in the pipe and the insertion depth of the electrodes in relation to the inside diameter of the pipe are
critical to the successful operation and calibration of the system. The brass rod that is supplied with the 2552 is used to assist with this
requirement.
4.4 H-Dimension
The H-dimension is the distance from the TOP OF THE PIPE to the BOTTOM OF THE BRASS ROD.
The tables on pages 8–11 include the H-dimension for two of the most common pipe schedules from DN50 to DN2550 (2 in. to 102 in.).
If the pipe is not represented in the tables on pages 8–11, use the procedure below to determine the H-dimension.
The goal of the procedure is to place the Magmeter electrodes 10% inside of the pipe
Hardware stack height is important
The H-dimension represents the total height
avaliable for the installation hardware.
If there is insuffi cient clearance to accommodate
the hardware, select a longer 2552 Magmeter or
modify the hardware to reduce the stack height.
