EZ-View Flow Meters

EZ-View Flow Meters

Hedland EZ-View® flow meters provide a lower cost alternative to standard Hedland flow meters. Made from high-impact thermoplastics like polysulfone and Radel®, these variable area meters (rotameters) contain a minimum number of moving parts, offering a reliable, trouble-free flow rate indicator. Fittings, available in brass, stainless steel and PVC, with NPT or BSP ports, allow the meter to be installed in a wide variety of applications. Meters can be used in oil and water processes, with the ability to add a flow switch, which can be used to trigger alarms.

How to Buy Hedland Flow Meters


The Hedland Flow Meter is a variable area (rotameter) instrument. A precision machined, sharp-edged Orifice is located within the piston assembly and forms an annular opening with the contoured metering cone. The piston assembly carries a cylindrical PPS/ ceramic magnet that is magnetically coupled to an external flow Indicator that moves precisely, in direct response to movement of the piston. A calibrated spring opposes flow in the forward direction. This spring decreases viscosity sensitivity and allows the flow meter to be used in any position, including inverted.

EZ-View Flow-Alert

EZ-View Flow-Alert More Info Less Info

The Hedland Flow-Alert is a variable area flow meter (rotameter) that provides a local flow indication and electronic switches to automatically signal system operators or PLCs if flow rate is below, or above, system specifications. Flow meter elements are enclosed within a NEMA 12 and 13 (IP 52/54) rated enclosure. Users can order meters with one or two Micro or Reed Switches, in normally open or closed states.

EZ-View Test Kit

EZ-View Test Kit More Info Less Info

Test kits enable Hedland variable area flow meters (rotameters) to provide additional system information and diagnostic capabilities. Standard flow meters are affixed with a pressure gauge and needle valve assembly, specifically designed to allow the operator to introduce a pressure load on the system. Various instruments within a system can be tested or verified against manufacturer specifications to ensure proper functionality. Instruments tested in this manner help promote fluid power safety by allowing operators to get a clear, visible indication of system health during operation, without the dangers of close contact with operating machinery.
