OVERVIEW
The HLZ series flow indicator sight glass is a monitoring device used to macroscopically indicate the flow rate of gas or liquid in pipelines. Especially for the flow rate of gases or colorless liquids, it is difficult to observe with a general pipeline sight glass, but using a flow indicator sight glass can clearly observe the flow state of the fluid.
