Overview of Variable Area Flow Meter
HH5 series variable area flow meter (also known as rotameter) 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 with metal tube. Metal tube variable area flow meter has the merit of little volume, broad measuring range and convenience for use. Rotameter variable area flow meter can be used to measure liquid, gas and vapor flow especially fits for the flow rate measurement of low flow velocity and low flow flow meter (low flow rotameter).SILVER AUTOMATION INSTRUMENTS is a China metal tube rotameter manufacturer to provide cheap digital rotameter flow meter.
HH5 series variable area rotameter has local indicator to display the instant flow which is normally accepted as flow indicator rotameter,Local indication without the need for auxiliary power, but we also havemetal tube rotameter with transmitterto have 4-20mA output or with Flow Alarm Switch Adjustable Throughout Flow Range, it is digital rotameter with LCD display to show instant/totalized flow. Our metal tube flow meter employs advanced microprocessing central chip and high-quality industrialized components of Motorola Corporation to ensure the good performances of flow meters in many application fields.
For many years variable area flow meter are well received by many industries such as petrochemical, steel and iron, electric power, metallurgy, light industry, food, pharmacy and water processing.
Custom rotameter according to customers’s specifications, we can make horizontal rotameter, thread connection rotameter, high temperature type rotameter.etc.
