8 inch variable area flow meter refers to the flow sensor size 8” of variable area flow meter , or it is DN200 variable area flow meter ; we also call variable area flow meter as rotor meter, VA flow meter. Silver Automation Instruments supply metal tube variable area flow meter with robust construction.
8 inch metal tube rotor flowmeter is a kind of variable area flow instrument used in industrial automation process control.
8” Rotameter flow meter can be used to measure the flow of liquid, gas and steam, and metal tube rotameter is especially suitable for medium flow measurement with low flow velocity and small flow rate.
DN200 variable area flow meter can be local indication of fluids flow rate without any power supply, it can also with 24V DC or 220V AC power supply to have totalized flow, 4-20mAoutput.
8 inch Variable area flowmeter material selection can be stainless steel 304, 316, 316L or PTFE lined to meet various kinds liquid measurement. Metal tube rotameter can measure clean liquid like drink water, RO water, fuel, diesel, organic solution or solvent or aggressive liquid such as sea water, acid, NaOH acid ,HCL .,etc. DN200 rotameter is widely used in petroleum, chemical, textile printing and dyeing, electric power and other industrial fields.
