Dynasonics MFX Series Insertion MagProbe Flow Meter - Manual (Page 6)

Rev. 01/11 -1.4- MFX
C. Measure the full length of the probe (E), calculate 12.5% of
the pipe I.D. (A), obtain the pipe wall thickness (B) and
measure the distance between the outer pipe wall and the top
of the insertion fitting (C).
D. Place a mark on the probe this is the proper distance from the
top of the probe (D):
D = E - A - B - C
E. Insert the MagProbe into the insertion fitting and secure with
the brass lock nuts—Series DMP2 - DMP6.
F. Open the ball valve and insert the probe to the distance
marked in step D. Secure with the brass nuts.
G. Rotate the probe in the pipe so that the FLOW DIRECTION
arrow points in the nominal forward flow direction (the MFX
system will read flow in both directions) and to within ±2° of
parallel to the pipe length.
4. ELECTRICAL CONNECTIONS
Run the MagProbe cables back to
the MFX transmitter mounting
location. Connect the MagProbe and
power to the appropriate terminal
connections within the MFX
enclosure. See Figure 1.2.
A. Do not run the probe cable
adjacent to electrically noisy
wiring.
B. Verify that the MFX is
configured for the power
supply that will be utilized in
the installation. Run power
through the left hand conduit
hole and secure to the proper
terminals.
C. Connect a 12 AWG (minimum)
ground wire between the
ground lug on the MagProbe
seal fitting and earth ground.
5. INITIAL SETTINGS AND POWER UP
A. Apply power to the instrument.
B. Verify that fluid velocity is indicated on the top line of the MFX
display.
C. Input proper units of measure and I/O data.
