5 Instruction Manual
Safmag Magprobe (Insertion mag)
Flow rate = ( 0 – 6 m/s ) / ( 0 – 18 ft/s )
The insertion probe must only be installed with the flow in the direction of the
arrow marking.
The alignment of the probe is important for accurate flow measurement, and care
should be taken to ensure that the point indicator on the terminal box mounting
plate points along the axis of the pipe. We recommend that the measuring section
of the probe is positioned at the centre of the pipe. As the probe has a 65mm
measuring window, this insertion depth is not critical but the following procedure
should be followed.
Installation
1. Measure the pipe Circumference and calculate the Outer Diameter. OD = C/π.
2. Measure the distance from the top of the securing nut to the pipe wall. (X)
3. Calculate the insertion depth from the probe tip A = X + (OD / 2) + 50mm.
4. Mark probe at “A” distance from the probe tip.
5. Care must be taken when installing under pressure. Make use of the threaded
bar and pull pate to safely pull the probe into place.
6. With the O-ring seal and securing nut in place insert the probe to the mark and
tighten the 4 allen screws to loosely clamp the probe.
7. Align the probe with arrow forward, check insertion depth and tighten securing
nut and probe clamp with four allen screws.
