Hehua glass rotamete

  Basic introduction and product introduction of Hehua glass rotameter
Glass rotameter is a variable area flowmeter, which is mainly composed of another vertical glass cone tube expanded from bottom to top and a float that can move up and down with the flow
Because there is a certain functional relationship between the flow through the flowmeter and the rising height of the float (i
e
the flow area of the flowmeter), the height position of the float can be used as the flow measurement indication
It is suitable for measuring the flow of single-phase non pulsating fluid (liquid or gas)
Glass rotameter is widely used in chemical industry, petroleum, light industry, medicine, environmental protection, food, measurement and testing, scientific research and other departments to measure the flow of single-phase non pulsating fluid (liquid or gas)

Performance characteristics of Hehua glass rotameter
40 series glass rotameter has the characteristics of high sensitivity, wide measurement range, small pressure loss and low requirements for the straight pipe section in front of the instrument
It is generally used to measure transparent liquid or gas with low pressure, normal temperature and no particle suspension
It is widely used in petroleum, chemical industry, steel, electronics, environmental protection, electric power, medicine and other industrial fields
