Introduction

INTRODUCTION

The Flow-Alert flow meter combines the rugged proven technology of a direct reading, piston-type variable area flow meter, coupled with electrical contacts used to signal operators or PLCs at customer-defined flow rates. This combination is sealed against industrial contamination by a NEMA 12 and 13 (IP52/54) rated enclosure (does not apply to strap versions).

This product provides a local flow indication and automatically signals the operator or PLC if flow is too high or too low.

Uses of the Flow-Alert flow meters include, but are not limited to: bearing lubrication, case drain verification, gun drill cooling and pump flow confirmation.

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.

THIS FLOW 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.

ALL FLOW ALERT FLOW METERS ARE UNIDIRECTIONAL AND HAVE NO BYPASS OPTION. ATTEMPTS TO FLOW FLUIDS IN THE OPPOSITE DIRECTION OF THE FLOW ARROW WILL RESULT IN THE FLOW 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 FLOW METER RESULTS.

DISCONNECT ELECTRICAL POWER BEFORE OPENING WIRING ENCLOSURE. FAILURE TO FOLLOW THESE INSTRUCTIONS COULD RESULT IN SERIOUS PERSONAL INJURY OR DEATH AND/OR DAMAGE TO THE EQUIPMENT.

ALL WIRING SHOULD BE INSTALLED IN ACCORDANCE WITH THE NATIONAL ELECTRICAL CODE AND MUST CONFORM TO ANY APPLICABLE STATE AND LOCAL CODES. FAILURE TO FOLLOW THESE INSTRUCTIONS COULD RESULT IN SERIOUS PERSONAL INJURY OR DEATH AND/OR DAMAGE TO THE EQUIPMENT.

AIR/GAS FLOW METERS ARE NOT OXYGEN CLEANED. USE WITH OXYGEN MAY CAUSE HAZARDOUS OR EXPLOSIVE CONDITIONS THAT MAY CAUSE SERIOUS

PERSONAL INJURY AND/OR DAMAGE TO THE EQUIPMENT.

Installation

Installation Recommendations

Hedland flow meters are designed for easy installation. However, the following measures are recommended for reliable, trouble-free operation:

• Piping should be accurately aligned and of correct length. The high pressure body of the flow meter can withstand shock and flow/pressure pulsation. Piping should be firmly supported by external mounting brackets, both upstream and downstream of the flow meter, to avoid any pipe flexing actions that could reduce flow meter life.

• If the flow meter inlet or outlet is rigidly mounted, and the opposing port is connected to flexible hose, the end connected with the flexible hose must be rigidly mounted.

• Install a union near the inlet or outlet of the flow meter to facilitate quick and easy flow meter removal and inspection during periodic maintenance procedures.

• Mount the flow meter either horizontally or vertically (flow arrow pointing to either side or straight up). If the flow meter must be mounted inverted, special inverted scales are available.

• Verify the fluid is traveling in the direction of the flow arrow, see Figure 1 on page 5.

• Systems that do not have filtration should be equipped with at least a 200 mesh (74 micron) filter. Most hydraulic system applications already have much finer filtration. The flow meter will allow particulates to pass that would jam most valves and flow controls.

Dirt, ferrous metal or sealing agents may lodge and cause malfunction. If the flow meter is jammed at a fixed position, follow cleaning and maintenance instructions.

• Do not use thread locking compounds as thread sealant.

• Do not install the flow meter near turbulence producing fittings such as elbows, reducers and close coupled valves for maximum reliability. The inline flow meter does not require flow straighteners or special lengths of straight inlet/outlet piping to stabilize turbulent flow patterns.

• Do not install the flow meter near fast-acting valves. Fast-acting valves have the potential to create high magnitude hydraulic pressure spikes. These spikes can damage the internal components of the flow meter, resulting in inaccuracies or malfunction.

• Do not operate flow meter against the direction of the flow arrow. The flow meter is unidirectional. The piston acts as a check valve to block flow in the reverse direction. This causes an excessive pressure differential, which can result in damage to internal flow meter components.

Reed Switch Congurations

Most units are equipped with an enclosure and a 15 ft (4.57 m) length of 4-wire #25 AWG type, PVC jacketed cable with a 4-pin Hirschmann connector.

Certain 1/4 in. or SAE 6 meters with lower flow ranges are equipped with a strap housing.

For safe operation of the reed switch, do not exceed the maximum wattage for that switch.

For example, the normally open (N.O.) reed switch has a maximum power rating of 10 Watts. If the switch is to operate at 24V DC, the maximum current is the wattage divided by the voltage.

I =

Exceeding the maximum power rating for a particular switch will damage it.

MAINTENANCE

Quick Recoupling

The piston type variable area flow meter is inherently less sensitive to shock and vibration than other variable area designs. The unique magnetic coupling also eliminates the need for mechanical linkages that can wear or loosen over the functional life of the flow meter.

However, a pressure spike or extreme flow surge can cause the piston to move at such rapid speed that it disconnects the piston magnet and the external indicator ring. If this occurs, use one of these procedures to recouple the magnet and the external indicator ring:

• If the system permits, simply change flow rate from “no flow” to “full flow” allowing the moving piston to magnetically recouple to the indicator ring.

• Remove the cover and manually reattach the external flow indicator to the internal magnet/piston assembly.

• For rigorous cyclical applications where decoupling may occur frequently, consult technical support.

DISCONNECT ELECTRICAL POWER BEFORE REMOVING THE FLOW METER COVER. FAILURE TO FOLLOW THESE INSTRUCTIONS COULD RESULT IN SERIOUS PERSONAL INJURY OR DEATH AND/OR DAMAGE TO THE EQUIPMENT.

Maintenance

2. Remove wiring, as needed, used for the ow switch(es).

OTE:N For configurations with an aluminum enclosure, wiring inside the enclosure does not need to

be disconnected, unless additional cleaning is required. Microswitch-equipped configurations may need to have wiring disconnected from the system to facilitate complete removal from the line. Reed switch configurations have a Hirshmann connector that can be disconnected from the enclosure.

3. Remove the ow meter from the line. Remove excess piping from the ow meter.

DO NOT USE AROMATIC HYDROCARBONS, HALOGENATED HYDROCARBONS, KETONES, OR ESTER BASED FLUIDS ON THE POLYCARBONATE LENS. FAILURE TO FOLLOW THESE INSTRUCTIONS COULD RESULT IN DAMAGE TO THE FLOW METER.

4. Thoroughly wipe o the entire ow meter surface using mild detergent or isopropyl

alcohol.

OTE:N For configurations with an aluminum enclosure, remove cover screws and front cover.

5. Using the end tting ats, clamp the outlet end tting, then remove the inlet end tting

by rotating it counterclockwise.

6. For congurations with an aluminum enclosure, remove the body from the enclosure

by gently pushing the body towards the outlet end of the enclosure, while holding the magnetic indicator assembly in place.

7. For congurations with the strap assembly, remove the inlet end cap, the plastic guard

and guard seals, ow scale and indictor magnet assembly. Remove the outlet end cap by pulling it toward the inlet.

8. The remaining parts are secured with a retaining ring inside the body. Remove the

retaining ring, piston/internal magnet and spring. Use caution to not bend or damage the retaining ring.

OTE:N If internal parts do not slide freely from the body, use a wooden dowel inserted into the outlet

port of the flow meter to push the parts out.

9. Place all parts on a clean work surface for cleaning and inspection. If parts appear to be

damaged, consult factory for repair/replacement options. Check the pressure and end tting/cap O-rings for damage and replace if required.

10. In reverse order, gently reassemble all parts back to their original conguration. Use

the groove on the indicator magnet and the middle n on the back of the ow scale to ensure proper alignment of the two. Ensure the ow scale is in its original location.

11. Reinstall the spring, followed by the piston/internal magnet and then the retaining ring.

12. Reinstall the cone/spider plate assembly and retaining spring, and secure with the inlet

end tting. If the conguration has an aluminum enclosure, secure the lid and ensure proper seating of the cover gasket by tightening the screws in a crisscross pattern. See

“Figure 6: Cover screw tightening sequence” on page 8.

13. Reinstall the ow meter in the line. Reconnect the electrical power.

Application Information

APPLICATION INFORMATION

Liquid

Viscosity Effect (SUS/cSt)

The design uses a precision machined, sharp-edged orifice and biasing calibration spring that assures operating stability and accuracy over the wide viscosity range, common to many fluids. High flow models of each flow meter size provide good accuracy over a viscosity range of 40…500 SUS (4.2…109 cSt).

Density Effect (specific gravity)

Any fluid density change from stated standards has a proportional effect on flow meter accuracy. Special scales can be supplied if actual specific gravity decreases accuracy beyond application limits. Corrections for more or less dense fluids can be made to standard scales using the following correction factor:

10.

Specific Gravity

for water/water-based flow meters

0 876.

Specific Gravity

for petroleum-based flow meters

Pneumatic

OTE:N Pressure and temperature readings must be taken at the flow meter inlet to provide accurate

correction factors.

The pneumatic flow meter is offered with a standard graduated dual scale, calibrated for air in standard cubic feet per minute (scfm) at 1.0 sg (70° F @ 100 psi) and liter per second (lps) at 1.0 sg (21° C @ 6.9 bar).

CONVERSION CHART

The conversion chart provides a series of simplified mathematical formulas to adjust the graduated scale for changes in pressure (Table 5), temperature (Table 6), and/or specific gravity (Table 7).

OTE:N Special scales can be made to accommodate other pressures, temperatures and

specific gravity.

The conversion chart can also be used to adjust the multi-pressure flow scale to indicate flow rates in applications beyond the parameters stated on the scale.

To adjust the pressures beyond (above or below) scale limits:

1. Locate the point at which the brightly colored indicator line intersects the vertical 100

Psig pressure line.

2. Divide this reading by the pressure correction factor (f1) indicated in Table 5.

To adjust for changes in temperature:

1. Divide the 100 Psig ow rate reading by the temperature correction factor (f2).

To adjust for changes in specific gravity:

1. Establish the square root of the new specic gravity.

2. Divide the 100 Psig ow rate reading by the Specic Gravity Correction Factor (f3).
