ASTM D4409-95-Reapproved2008<\/h3>\n

Historical Standard: Standard Test Method for Velocity Measurements of Water in Open Channels with Rotating Element Current Meters<\/h4>\n
\n

ASTM D4409<\/h4>\n

Scope<\/strong><\/p>\n

1.1 This test method describes the design and use of cup-type or vane-type vertical axis current meters and propeller-type horizontal axis current meters for measuring water velocities in open channels.<\/p>\n

1.2 This test method is intended primarily for those meters customarily used in open-channel hydraulic (as distinguished from oceanographic) applications with an operator in attendance.<\/p>\n

1.3 This test method is intended primarily for current meters that measure one component or filament of flow.<\/p>\n

1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.<\/p>\n

1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.<\/span><\/p>\n
