The EZ-View® variable area flow meters are rugged, low-cost direct reading meters for flow measurement of oil, water and other fluids. They are very simple to install - in any orientation from vertical to horizontal, upside down, etc. without sacrificing measurement performance.
Constructed of high impact PPSU, the EZ-View® product line offers excellent structural integrity and chemical compatibility with a wide range of industrial chemicals. EZ-View® flow meters provide instantaneous, direct-reading flow rate measurement of liquids in closed piping systems. They measure oil in a flow range of 10 to 380 l/min, water from 2 to 380 l/min and water-based fluids from 2 to 100 l/min.
The transparent PPSU body allows visual inspection of the fluid condition as well as viewing of the internal flow indicator relative to a calibrated flow scale. EZ-View® does not require electrical connections.
Flow straighteners, located in the inlet and outlet, allow the flow meter to be less sensitive to turbulent flow conditions. Further straighteners or other special installations are not required.
Variable area flow meters
The variable area flow measurement method allows fluids (liquids and gases) volume streams to be determined. A moving sharp-edged orifice is located within the piston assembly, forming an annular opening with the contoured metering cone. The piston assembly carries a cylindrical PPS/ceramic magnet that is magnetically coupled to an eternal indicating magnet, which moves precisely in direct response to movement of the piston therefore providing a visual display of the flow rate.
