with Float Flow Measurement of Gases & Clear Liquids with Float Measurement Principle Variable area obtained by the displacement of a float in a conical, Borosilicate glass tube. Commonly used in industry to measure the flow for: • Water treatment. • Chemical processes. • Industrial Refrigeration & Air Conditioning. • Research Laboratories. • Pilot Plants. • Annealing Furnaces. • Easy Installation, no straight pipe required. • Adjustable alarms, in all scales, operated magnetically or with infra-red light. • Measuring tube in Borosilicate glass. • Steel construction, coated with Polyamide 11. • Connections in Steel, AISI-316, PVC & PTFE.

Reading Line The fluid flows up through the tapered tube forcing the float to a position with sufficient free area to enable the flow to pass. This free area is related to the flow rate, the weight of the float and the density and viscosity of the fluid. The pressure drop across the flow meter remains constant over the entire flow range. This occurs because the pressu- re drop is related to the fluid velocity and area of flow, the area of flow increases as the flow rate increases.
