HH5 Variable Area Flow meter
Available: Liquid, Gas, Steam.
Not For: High viscosity fluid.
HH5 series variable area flow meter is a kind of measuring meter which the flow rate is changing along with the area and is widely used in the process control of industrial automation. It has the merit of little volume, broad measuring range and convenience for use. It can be used to measure liquid, gas and vapor flow especially fits for the flow rate measurement of low flow velocity and little flow rate.
HH5 series variable area flow meter has local indication type and smart remote type with a pointer LCD displaying instantaneous/ accumulated flow rate, upper-limit and lower-limit alarm output, accumulative pulse output, batch control, standard two-wire 4-20mA current output, ect. Additionally, this instrument employs advanced microprocessing central chip and high-quality industrialized components of Motorola Corporation to ensure the good performances of flow meters in all application fields.
For many years variable area flow mete rare well received by many industries such as petrochemical, steel and iron, electric power, metallurgy, light industry, food, pharmacy and water processing.
