Practical Notes
Always install a strainer (dirt box) upstream of the bulk water meter to protect the impeller mechanism from debris.
Maintain a straight pipe length of at least 10 times the diameter (10D) upstream and 5D downstream to ensure a uniform flow profile and accurate measurement.
Ensure flanged connections are properly aligned and gaskets do not protrude into the pipe, as this can cause turbulence and affect meter accuracy.
