INTRODUCTION

The Inline Liquid Flow Meter is a rugged industrial class inline flow rate indicator, offered in aluminum, brass or stainless steel models to monitor a wide variety of liquids. Available in seven port sizes from 1/4" to 3" for flow ranges from 0.02…0.20 (0.1…0.75) through 20…300 gpm (100…1100 lpm), the meters are calibrated at 0.876 specific gravity for oil or other petroleum-based fluids, 1.0 for water or other water-based fluids, or 1.18 for phosphate ester liquids.
The flow meter is equipped with a 360° rotatable guard/scale which allows the meter to be installed in any orientation without regard to scale direction. Once the meter is permanently installed, the guard/scale can be rotated 360° to optimize readability.
In addition, the unique spring-loaded design of this variable area flow meter decreases viscosity sensitivity and allows it to be installed in any position, including inverted, without affecting accuracy. An optional inverted scale is available for these applications.
The standard flow meter is a unidirectional device. If required, a reverse flow bypass option is available for the oil, phosphate ester and water-based fluid models. Note that flow is measured in the forward direction only.
• Aluminum models are offered as a rugged, low cost flow meter for monitoring noncorrosive water-based or petroleum-based fluids under operating pressures up to 3500 psi (241 bar).
• Brass meters are recommended for water monitoring applications or other systems where corrosion inhibitors are not present.
• Stainless Steel is available for monitoring hydraulic systems operating at pressures up to 6000 psi (414 bar) or other corrosive caustic fluids, such as acetic acid. For further construction material information, see
"Fluid selection chart" on page 16.

OPERATING PRINCIPLE

The Flow Meter is a variable area instrument. A sharp-edged Orifice, located within the Piston Assembly, 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 Indicating Magnet which moves precisely in direct response to movement of the piston. A calibrated Spring opposes flow in the forward direction.
The Hedland variable area flow meters are the most readable products in their class. Brightly colored indicators move over the graduated, linear Flow Scale which contains bold, easy to read numeral and gauge marks. The enhanced resolution virtually eliminates parallax problems associated with competitive, direct reading flow meters.

INSTALLATION

THIS PRODUCT SHOULD BE INSTALLED AND SERVICED BY TECHNICALLY QUALIFIED PERSONNEL TRAINED IN MAINTAINING INDUSTRIAL CLASS FLOW INSTRUMENTATION AND PROCESSING EQUIPMENT.
READ INSTRUCTIONS THOROUGHLY BEFORE INSTALLING THE UNIT. IF YOU HAVE ANY QUESTIONS REGARDING PRODUCT INSTALLATION OR MAINTENANCE, CALL YOUR LOCAL SUPPLIER FOR MORE INFORMATION.
OIL METERS ARE NOT RECOMMENDED FOR WATER MONITORING APPLICATIONS. IF METER IS TO BE SUBJECTED TO BOTH OIL AND WATER, WATER METERS (BRASS) ARE SUGGESTED. CONSULT FACTORY FOR DETAILS.
THIS METER MAY CONTAIN RESIDUAL AMOUNTS OF TEST FLUID AT THE TIME OF SHIPMENT. THIS FLUID SHOULD BE REMOVED PRIOR TO INSTALLATION AS THE FLUID MAY BE INCOMPATIBLE OR HAZARDOUS WITH SOME LIQUIDS OR GASES. FAILURE TO FOLLOW THESE INSTRUCTIONS COULD RESULT IN DAMAGE TO THE EQUIPMENT.
THIS STANDARD METER IS UNIDIRECTIONAL. ATTEMPTS TO FLOW FLUIDS IN THE OPPOSITE DIRECTION OF THE FLOW ARROW WILL RESULT IN THE METER ACTING AS A CHECK VALVE, CREATING A DEADHEADING SITUATION. IF THE DIFFERENTIAL PRESSURE MAGNITUDE IS GREAT ENOUGH, DAMAGE TO THE INTERNAL PARTS OF THE METER WILL RESULT.
The inline flow meter is a simple device to install. However, the following measures are recommended for reliable, trouble­free operation:
• Align pipe accurately. Piping should be accurately aligned and of correct length. The high pressure body of the flow meter can withstand shock and flow/pressure pulsation. However, the piping should be firmly supported by external mounting brackets, both upstream and downstream of the meter, to avoid any pipe flexing actions that could reduce meter life.
• Use rigid mounting. If the flow meter inlet or outlet are to be rigidly mounted, and the opposing port is to be connected to flexible hose, the end connected with the flexible hose must be rigidly mounted.
• Use Teflon® tape for sealing NPT fitting.
• Install unions. Install a union near the inlet or outlet of the meter. This will facilitate quick, easy meter removal and inspection during periodic maintenance procedures.
• Mount the meter either horizontally or vertically (flow arrow pointing to either side or straight up). If the meter must be mounted inverted, special inverted scales are available from the factory.
• Ensure the fluid is traveling in the direction of the flow arrow (Figure 1).
• Use at least a 200 mesh (74 micron) filter. The meter will allow particulate to pass that would jam most valves and flow controls. Systems that do not have filtration should be equipped with at least a 200 mesh (74 micron) filter. Most hydraulic systems already have much finer filtration.
• Dirt, ferrous metal or sealing agents, such as Teflon® tape may lodge and cause malfunction. If the meter is jammed at a fixed position, follow cleaning and maintenance instructions.
• Do not use thread locking compounds as thread sealant.
