DAW, whose body is made of PVC (Polyvinyl Chloride), is a differential pressure flow meter having wafer type connection. This can easily measure flow rate of both gases and liquids while specially designed to be most suitable for corrosive fluids.
This type is manufactured with a small diameter up to a large diameter for measuring a minute flow up to a large flow accordingly. This flow meter is of analog type for checking the flow rate by reading the gradation and is not restricted by the direction of the fluid flow.
