不仅如此,由于该水流量测定仪中的集水袋以及测流袋均为柔性部件,该水流量测定仪还具有便于携带的优点。又由于切换装置的存在,该水流量测定仪还能够减少因水流不稳定而带来的误差,进一步的提高测量精度。Not only that, since both the water collecting bag and the flow measuring bag in the water flow measuring instrument are flexible parts, the water flow measuring instrument also has the advantage of being easy to carry. In addition, due to the existence of the switching device, the water flow measuring instrument can also reduce errors caused by unstable water flow, and further improve the measurement accuracy.

以上所述,仅为本实用新型较佳的具体实施方式,但本实用新型的保护范围并不局限于此,任何熟悉本技术领域的技术人员在本实用新型揭露的技术范围内,可轻易想到的变化或替换,都应涵盖在本实用新型的保护范围之内。The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited to this. The changes or replacements should be covered within the protection scope of the present invention.
