An area flow meter has a float in a conical cylinder (tapered tube) with a larger end in the upper section and a smaller end in the lower section. The float moves up and down according to the intensity of the flow, and the position at which the float balances indicates the flow rate. Not only simple flow meters that merely measure the flow rate but also flow meters with a valve for flow control, flow meters with a load pressure fluctuation type flow controller, flow meters with a supply pressure fluctuation type flow controller, and flow meters with an alarm switch are available.
Kofloc Model RK1650 Flowmeter
This is a completely renewed model of existing KOFLOC RK1600R with sophisticated design to fit sophisticated laboratory or plant equipment.
- Compact. A compact flowmeter with variations of total length of 84 mm, 104 mm, 124 mm and 154 mm for choice according to the user’s needs
- Low pressure loss. Pressure loss minimized to allow applications for low supply pressure
- Choice of needle valve to suit the user’s needs. Four types of needle valve available for your choice according to the requirement of supply pressure
- Superior stability. All tubes are precision-formed to provide the float with outstanding repeatability and stability.
- Economical. A flowmeter at quite affordable price achieved through our all-out effort at streamlined design
- For environmental instrumentation systems
- For general instruments for analysis
- For purge systems
- For semiconductor manufacturing equipment
