Gusts can cause variations in the test section dynamic pressure, and in the distribution of dynamic pressure across the test section. 陣風會使試驗段動壓和試驗段截面動壓分佈發生變化。
Under favourable circumstances hydrodynamic pressure may be generated to oppose the flow due to the applied pressure. 在有利的環境下，可產生流體動壓力來阻止由所加壓力引起的流動。
In order to avoid being affected by sudden change of measured medium or pulsant pressure, additional buffers should be installed. 為了保證儀錶不受被測介質的急劇變化或脈動壓力的影響，加裝緩衝器。
