(Special accessories on the pipeline, circulating pump parts, power supply desulphurization supplies)(2) The flow indicator is a practical product that is easy to observe and install.At least it can be determined that there is a medium passing. Both ends can be used as an entrance, simple, straightforward and reliable. The flow rate can be estimated by observing the rotational speed of the rotor. The flow indicator allows the lens to be easily removed for cleaning. The impeller flow indicator is a practical product that is easy to observe and install.(3) Characteristics of the flow indicator1. The window surface glass is easy to clean.2. The glass window can be viewed in the 180° direction.3. Horizontal dual use for easy installation or disassembly.Packing including：1*Sight Water Flow Indicator with Plastic Impeller
