Hedland EZ-View Flow Meter

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.

Details

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.

BENEFITS

No electronics needed to obtain a reading
Can be installed in any position / orientation without affecting accuracy
The most readable product in its class
Does not require special plumbing or accessories to stabilize turbulent flow
Magnetic coupling eliminates the need for mechanical linkages that wear, loosen and leak over the functional life of competitive meters
Custom scale options to meet exact application requirements
Material options for standard or more aggressive fluid media
