High precision glass tube rotameter 

No external power supply required-Glass Tube Rotameter is a mechanical device that does not require a power supply to provide flow measurement. This allows the Glass Tube Rotameter to be installed in hazardous areas and remote areas where electricity is expensive The product is easy to install and can prevent corrosion G/R/F10, 20, 30 glass tube flowmeters are connected with pipe thread (G10, 20, 30 type), hose (R10, 20, 30 type); flange (F10, 20, 30 type) three Kind of way. Its pressure and temperature resistance are higher than the original LZB/LZJ series glass rotor flowmeter products of the same diameter; it is divided into ordinary type (measurement of general non-corrosive fluid) and corrosion-resistant type (measurement of corrosive fluid). The product is small in size, light in structure, beautiful in appearance, convenient in maintenance, safe and reliable, and simple in installati…
