Historical Standard: ASTM D4409-95(1999) Standard Test Method for Velocity Measurements of Water in Open Channels with Rotating Element Current Meters
SUPERSEDED (see Active link, below)
ASTM D4409
1. Scope
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.
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.
1.3 This test method is intended primarily for current meters that measure one component or filament of flow.
1.4 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.
