迄今为止,HLJ_1-1型印刷海流计(下称仪器)仍是我国海洋调查的主要测流仪器之一。由于它具备自记、自含(机械性)的特点,应用颇为广泛。该型仪器内有六种时间控制轮,分为5、10、15、20、30及60分钟的取样时间间隔。使用时可按需要任选一种来控制记录的时间,择其不同的控制时间,可对应地记录不同的连续观测天数。其对应关系参见表1。
So far, HLJ_1-1 printing current meter (hereinafter referred to as the instrument) is still one of the main flow measurement instruments in China’s marine survey. Because of its self-recorded, self-contained (mechanical) features, the application is quite extensive. There are six types of time control wheels in the instrument, divided into sampling intervals of 5, 10, 15, 20, 30 and 60 minutes. When in use, the time of recording can be controlled according to the need. Depending on the control time, different continuous observation days can be recorded correspondingly. See Table 1 for the correspondence.
