Glass Tube Rotameter
This rotameter has the features of high sensitivity, wide measuring range, low pressure loss, easy to operate and maintenance, etc. It is usually used to measure transparent liquid and gas with low pressure, high temperature, and without suspended particles. It has been widely used in petroleum, chemical, electronics, environmental protection, power supply, medicine and other industries.
