Sometimes I don't notice a decrease in the flow of coolant to the welding machine, and then the machine's temperature gets hot causing machine trouble.
我有时发现不了焊接枪冷却水流量下降， 结果机器发热造成故障。
How do you control the coolant flow?
你是怎样管理冷却水流量呢？
I'm using a float type flow meter, however when the coolant gets dirty the flow indicator is difficult to read. Do you have any good ideas?
我用浮标式流量计进行管理，但是当冷却水脏污时，很难看清显示屏。有什么好办法吗？
If that's the case you should consider using a non-wetted electrode electromagnetic flow sensor. It has no paddle wheels, electrodes or obstructions in its pipe, so even if the coolant is dirty the pipe will not get clogged and the flow indicator is always easy clear visible.
