About This Item
ASTM D1941 is the standard test method for open channel flow measurement of water with the Parshall flume. It provides a recognized technical reference for measuring water flow in open channels using this specific flow device, helping users support consistent readings and comparable results. For projects that rely on accurate water measurement, the standard can be an important part of documentation, system evaluation, and quality control.
ASTM D1941 standard overview
The ASTM D1941 standard focuses on a practical method for determining water flow in open channels with a Parshall flume. As a test method, it is centered on measurement approach rather than product manufacture, making it useful when flow data must be gathered in a repeatable and defensible way. The title indicates a narrow and clearly defined technical scope, which helps users apply the document to the correct flow-measurement setup and avoid inconsistent interpretation.
Where is ASTM D1941 used?
This standard is commonly used wherever open channel water flow must be measured with a Parshall flume. That may include wastewater or water management systems, field monitoring locations, and other hydraulic installations using this type of flume for flow determination. ASTM D1941 is relevant when technicians, engineers, or operators need a dependable reference for measurement procedures tied to the flume’s geometry and operating conditions.
Practical importance of ASTM D1941
In practice, ASTM D1941 helps support consistent flow measurement and reduces uncertainty when using a Parshall flume. It can be useful for compliance efforts, procurement of measurement equipment, performance verification, and routine testing workflows. By relying on a standard method, organizations can improve comparability between readings, strengthen records for reporting, and lower the risk of errors in open channel water measurement.
