网口流量计

数字网口流量计MF315可用于多种拖曳式采样设备，例如浮游生物网等；或者固定于某站位，用于监测河流或排水口的流量。MF315数字流量计通过单点或两点固定于相应采样工具上，通过叶轮的转数，计算流过设备的水量。根据采样工具的不同，流量计有两种不同的使用形式：（1）流量计配合水下拖体等设备使用时，可以通过单点与设备连接；（2）流量计与浮游生物网连接时，通过两点固定定于浮游生物网的网口。型号产品描述材料叶轮聚酰胺, PA 6.6 尼龙转子鼻翼POM塑料主体POM塑料齿轮轴不锈钢尺寸总长21.3cm直径4.15cm其它参数深度等级无限制 (自由浸水)读出数据六位十进制的计数轮，读数从000000到999999. 计算器999999 计数，每10个数进一位最低转速20 cm/秒转速范围20 cm/秒到 10,0m/秒精度±3%
