又叫 转子流量计 ， 浮子流量计原理设想发轫于19 世纪 60 年代， 20 实际初出现商品。 The float flow meter is also called a rotor flow meter . The principle of the float flow meter was conceived to originate in the 1860s , and the commodity actually appeared in the early 20s. Has become one of the most widely used instruments. The glass tube float flow meter has a simple structure and a low price. As long as the flow indicator is convenient to use at the scene, the disadvantage is that there is a risk of fragility of the glass tube, especially the non-guided structure float for gas. The metal tube float flow meter has no risk of cone tube breakage. Compared with the glass tube float flowmeter, the operating temperature and pressure range is wide.
Classified by cone tube material: float meter with transparent cone tube and metal tube.
Classified by the fluid to be measured: liquid, gas, and steam float meters.
Classified by the amount of fluid passing through the flow meter: full flow type flow meter, split flow meter
流量计 。 Classification by remote signal output: local indication type and remote signal output type float flowmeter .
玻璃管浮子流量计 ，这种流量计 结构 非常 简单，价格 很低 。 Each of the above flowmeters has its own advantages and disadvantages, such as glass tube float flowmeters . This flowmeter has a very simple structure and a low price . 使用 起来非常的 方便，缺点 就是 是有玻璃管 破 碎的风险，尤其是无导向结构浮子用于气体。 It is easy to use and very convenient to use. The disadvantage is the risk of glass tube breaking , especially the non-guided structure float for gas. 就没有 锥管破裂的风险。 Metal tube float flowmeters do not have the risk of cone tube breakage. 也比较 宽。 Compared with the glass tube float flowmeter, the operating temperature and pressure range is also wider.
