What is BS 5857-1.2 - Constant rate injection method about?
BS 5857-1.2 is an International Standard that discusses the fluid flow in closed conduits, using tracers.
BS 5857-1.2 specifies the constant rate injection method using non-radioactive tracers for the measurement of water flow rate in closed conduits.
Flow rate measurement by a constant rate injection method is based on a comparison between the concentration C1 of a tracer, continuously introduced with a known volume rate of flow q, and the concentration of samples C2 taken at some place beyond the mixing distance.
Who is BS 5857-1.2 - Constant rate injection method for?
BS 5857-1.2 on constant rate injection method is useful for:
- Manufacturers and designers of flowmeters, transducers, and flow transmitters
- Testing laboratories
- Water resource engineers
- Hydrologists
- Quality control and testing authorities
- Regulatory authorities
Why should you use BS 5857-1.2 - Constant rate injection method?
Constant rate injection method comprises the injection of a suitable tracer solution, either as a sudden input or at a constant rate over a period, and the subsequent recovery and analysis of samples from the stream at a point downstream.
BS 5857-1.2 is the second part of a series of standards covering tracer methods of water flow measurement in closed conduits. BS 5857-1.2 assists with the general requirements of tracer for the constant rate injection method. BS 5857-1.2 helps you to make a better choice of measuring length. BS 5857-1.2 provides you with guidelines for the various test methods and their procedures.
By adopting, BS 5857-1.2 you can learn about the methods for measurement of fluid flow in closed conduits, using tracers which can help you in understanding the methods of hydraulic measurements.
