Instructions for Inline Flowmeter Placement
Install the MTL10 Inline style flowmeter so that it is far enough away
from bends in the pipe, obstructions, or changes in line sizes to ensure
a consistent flow profile. Eight diameters of straight pipe upstream and
four downstream are recommended (for ¼" meters: 6” (152 mm) of
straight, unobstructed pipe upstream and downstream are required).
For example, a 2" pipe would require 16" upstream from the edge of
the flow body and 8" downstream from the other end of the flow body,
whereas a 4" pipe would require 32" upstream and 16" downstream.
The MTL10 is welded, threaded or flanged to the customer’s pipe. Care
should be taken to ensure that the diameter of the mating pipe is the
same diameter as the MTL10 flow body or errors in flow readings can
occur. The installation procedure should be a combination of the end
user’s best engineering practices, in compliance with local codes, and
the manufacturer’s recommendations.
See Figure 2.7 for a detailed look at upstream and downstream pipe
diameters for inline meters.
