ISO 2425:2010总结了潮汐通道中液体流量测定的推荐方法，特别考虑了潮汐条件下唯一或特别适用的技术，包括不确定性的处理。 在适当的情况下，还参考了非潮汐水道中流量测定的方法，但需要注意它们在实用性和/或不确定性方面的局限性。 ISO 2425:2010没有描述替代方法，例如使用堰、水槽、稀释度测量、盐速和浮标，尽管它们可能适用于某些条件，尤其是在潮汐影响仅阻碍且不阻止或逆转水流通过的情况下。 这些方法在其他国际标准中有详细描述。 ISO 2425:2010规定了两种技术:潮汐流量的单一测量技术；潮汐流连续测量技术。 附录A规定了容积测量方法。附录B规定了潮汐条件下流量的确定方法，附录C给出了单个垂直管道的计算示例。其他垂直方向也可以进行类似的计算。附录D描述了使用声学多普勒速度计测定潮汐流量。

ISO 2425:2010 provides a summary of recommended methods for the determination of liquid flow in tidal channels, special consideration being given to those techniques that are either unique to or particularly appropriate for application under tidal conditions, including treatment of uncertainties. Reference is also made, where appropriate, to methods for the determination of flow in non-tidal channels, but attention is drawn to their limitations with respect to practicality and/or uncertainty. ISO 2425:2010 does not describe alternative methods, such as the use of weirs, flumes, dilution gauging, salt velocity and floats, although they might be suitable under certain conditions, especially where the effect of tides only impedes and does not stop or reverse the passage of stream flow. These methods are described in detail in other International Standards. ISO 2425:2010 specifies two types of technique: techniques for single measurements of tidal flow; techniques for continuous measurement of tidal flow. Annex A specifies the cubature method of measurement. Annex B specifies methods for the determination of flow under tidal conditions, and Annex C gives an example of the computation for a single vertical. Similar computations are possible for other verticals. Annex D describes the determination of tidal flow using an acoustic Doppler velocity meter.
