What is 6 inch variable area flowmeter ?
6 inch variable area flowmeter refer to the variable area flow meter with diameter 6” or DN150, the flange could be ANSI, 150LB, 300LB; JIS10K ,etc. We often call this type flow meter 6 inch rotameter. 6 inch variable area flowmeter is large size VA flow meters.
What is a variable area flow meter?
The working principle of the variable area flow meter is in a vertical cone tube that expands from bottom to top. The gravity of the float with a circular cross section is borne by the hydrodynamic force, and the float can be in the cone. The tube rises and falls freely. It moves up and down under the action of flow velocity and buoyancy, and after balancing with the weight of the float, it is transmitted to the dial to indicate the flow rate through a magnetic coupling. The rotameter is a kind of variable area flowmeter, 6 inch variable area flow meter also apply for that principle.
What does the variable flow measure?
Variable area flow meter is a very cost-effective flowmeter with a wide range of applications. It can be used for the measurement of liquids and gases including vapor in the process industry.
It can be used in many critical applications, such as high temperature oil, mineral Oil; it is also very good at low flow rate liquid or gas measurement. 6” rotameter can take volumetric flow rate measurement of air, compressed air, natural gas, RO water, vegetable oil.etc.
What are the advantages of using a variable area flow meter?
Variable area flow meter is a very cost-effective flow meter.
6 inch variable area rotameter has simple structure, low pressure loss and convenient maintenance.
Low price cost DN150 variable area flow meter; price starts from $ 1000
6 inch variable area flow meter can take measurement of flow rate when there is no power supply
Can be used with flow transmitter to have 4-20mA , HART protocol, Modbus, switch alarm outputs
Digital 6 inch variable area flow meter options to totalized flow , 220V AC , 24V DC or battery power supply options.
Wet parts material can be stainless steel 304, 316, 316L for different applications demands.
6 inch variable area flow meter can be used for low flow velocity and small flow liquid or gas measurement
