6.8 The Single-Traverse Method - MCF
The single-traverse MCF consists of two sections. Each section includes two magnetic blocks which are connected by
two parallel rods. In addition, a sliding transducer block, which is used to hold the transducer in proper alignment, is
mounted on the two rods. The two sections are mounted on opposite sides of the pipe from each other.
Note: In some applications, an MCF with two transducer blocks is used.
WARNING! Do not use the MCF at temperatures that exceed 120°F (49°C) or the fixture will fall off the pipe.
Note: The instructions in this section can also be used for a multiple-traverse method. However, you must use an
ODD number of traverses. Consult the factory for details.
To install a single-traverse MCF, complete the following steps:
1. Obtain the transducer spacing dimension, as described in your flowmeter User's Manual.
2. Be sure the location you have chosen for the installation has a straight pipe and undisturbed flow for at least 10
pipe diameters upstream and 5 pipe diameters downstream from the flow measurement point.
3. Prepare the pipe where you intend to place the clamping fixture by making sure it is clean and free of loose
material. Sanding, though usually not required, may be necessary to remove any high spots on the pipe. When
sanding, be careful to preserve the original curvature of the pipe.
4. Find the top of the pipe and use a level to draw a line parallel to the center line of the pipe.
