We are offering glass tube rotameter with nozzle :the glass tube rotameter is relatively simple and reliable instruments for the continuous flow rate indication. Manufacturing process :this rotameter consists of a vertical mounted, calibrated with tapered glass tube, with float inside and a scale directly calibrated, as per flow range. Glass tube field is replicable, without disturbing the end connection. How it works :your line fluid raises the float in tapered glass tube area, increases float, which moves upward, thereby showing the exact (increasing) flow, in the glass tube. Uses :glass tube rota meter are generally used for air, water, chemical and gases. Specification : type : direct online metering tube : borosilicate taper glass tube casing protection ; m.s. .s.s casing from 2 sides, guard for glass tube and clear acrylic front & back.
