摘要:
A flow measuring device has a housing (1), an impeller wheel (19), an orifice (20), a speed measuring device and an evaluating device (31). Further, there is an orifice cleaning device with at least one cleaning element (40), which acts upon the orifice (20) by means of an operating device (37), thus loosening impurities, particularly inside the orifice. Thus, a high measuring accuracy can be maintained for a long period, even with small flows.
摘要(中):
流量测量装置具有壳体(1),叶轮(19),孔口(20),速度测量装置和评估装置(31)。 此外,还有一种具有至少一个清洁元件(40)的孔口清洁装置,其通过操作装置(37)作用在孔口(20)上,从而松动杂质,特别是在孔口内。 因此,即使在小流量的情况下,也可以长时间保持高的测量精度。
