Installation & Operation Manual

I  INTRODUCTION

The Flow-Alert ow meter combines the rugged proven technology of a direct reading, piston-type, variable area ow meter, coupled with electrical contacts utilized to signal at selected ow rates. This combination is sealed against industrial contamination by a NEMA 12 and 13 (IP52/54) rated enclosure.

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

Uses of the Flow-Alert ow meter include: bearing lubrication, case drain verication, gun drill cooling, pump ow conrmation, etc.

III  INSTALLATION

CAUTION

Caution - This product should be installed and serviced by technically qualied personnel trained in maintaining industrial class ow instrumentation and processing equipment.

CAUTION

Caution - Read instructions thoroughly before installing the unit. If you have any questions regarding product installation or maintenance, call your local supplier for more information.

CAUTION

Caution - This meter may contain residual amounts of test uid at the time of shipment. This uid should be removed prior to installation as the uid may be incompatible or hazardous with some liquids or gases. Failure to follow these

WARNING

Warning - 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.

WARNING

Warning - 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.

CAUTION

Caution - Air/gas 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.

CAUTION

Caution - This standard meter is unidirectional. Attempts to ow uids in the opposite direction of the ow arrow will result in the meter acting as a check valve, creating a deadheading situation. If the dierential pressure magnitude is great enough, damage to the internal parts of the meter will result.

Form #04-VAM-UM-00229 09/12 Page 5

INSTALLATION RECOMMENDATIONS

The in-line ow meter is a simple device to install. However, the following measures are recommended for reliable, trouble-free operation:

Do - Align pipe accurately. Piping should be accurately aligned and of correct length. The high pressure body of the ow meter can withstand shock and ow/pressure pulsation. However, the piping should be rmly supported by external mounting brackets, both upstream and downstream of the meter, to avoid any pipe exing actions that could reduce meter life.

Do - Use rigid mounting. If the ow meter inlet or outlet are to be rigidly mounted, and the opposing port is to be connected to exible hose, the end connected with the exible hose must be rigidly mounted.

Do - Use Teon® tape for sealing NPT tting.

Do - 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.

Do - Mount the meter either horizontally or vertically (ow arrow pointing to either side or straight up). If the meter must be mounted inverted, special inverted scales are available from the factory.

Do - Use at least a 200 mesh (74 micron) lter. The meter will allow particulate to pass that would jam most valves and ow controls. Systems that do not have ltration should be equipped with at least a 200 mesh (74 micron) lter. Most hydraulic systems already have much ner ltration.

Dirt, ferrous metal or sealing agents, such as Teon® tape may lodge and cause malfunction. If the meter is jammed at a xed position, follow cleaning and maintenance instructions.

Don’t - Use thread locking compounds as thread sealant.

Don’t - Install the ow meter near turbulence producing ttings such as elbows, reducers, close coupled valves, etc. The in-line ow meter does not require ow straighteners or special lengths of straight inlet/ outlet piping to stabilize turbulent ow patterns. However, to assure maximum operational reliability, avoid installation of elbows, valves and/or reducers immediately adjacent to the meter inlet.

Do - Ensure the uid is traveling in the direction of the ow arrow (Figure 4 on page 8).

Page 6 Form #04-VAM-UM-00229 09/12

Don’t - Install the meter near fastacting valves. Fast-acting valves have the potential to create high magnitude hydraulic pressure spikes. These spikes can damage the internal components of the meter, resulting in inaccuracies or malfunction.

3. See Figure 6. After installation, rotate meter by hand to view

ow scale.

ELECTRICAL CONNECTIONS

Equipped Models

Don’t - Allow unidirectional meters

to be operated against the direction of the ow arrow. The standard ow meter is an unidirectional ow meter. The piston acts as a check valve to block ow in the reverse direction. This causes an excessive pressure dierential, which can

NOTE: In-line meters with a reverse ow by-pass feature are available. Consult factory for details.

INSTALLING THE FLOWALERT

1. See Figure 4. Mount the meter so uid is traveling in the direction of the ow arrow.

2. See Figure 5. Select a mounting location that is suitable for viewing and product service. To connect the ow meter into the piping system, place an open-

Quick Re-Coupling

This piston-type variable area ow 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 meter.

However, on occasion, a pressure spike or extreme ow 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 re-couple the magnet and the external indicator ring:

• If the system permits, simply change ow rate from “no ow” to “full ow” allowing the moving piston to magnetically re-couple to the indicator ring.

• Remove cover and manually re-attach external ow indicator to internal magnet/ piston assembly.

• For rigorous cyclical applications where decoupling may occur frequently, consult the technical services sta for further recommendations.

APPLICATION

INFORMATION  PNEUMATIC

APPLICATION

INFORMATION  LIQUID

Viscosity Eect (SUS/cSt)

The design utilizes a precision machined, sharp-edged orice and biasing calibration spring that assures operating stability and accuracy over the wide viscosity range common to many uids. Generally, high ow models of each meter size provide good accuracy over a viscosity range of 40 to 500 SUS (4.2 to 109 cSt).

Density Eect

(specic gravity)

Any uid density change from stated standards has a proportional eect on meter accuracy. Special scales can be supplied if actual specic gravity decreases accuracy beyond application limits. Corrections for more or less dense uids can be made to standard scales using the following correction factor:

Specic Gravity

NOTE: Pressure and temperature readings must be taken at the ow meter inlet to ensure accurate correction factors.

The pneumatic ow meter is oered with a standard graduated dual scale, calibrated for air in standard cubic feet per minute (scfm) at 1.0 s.g. (70 °F @ 100 psi), and liter per second (lps) at 1.0 s.g. (21 °C @ 6.9 bar).

Conversion Chart

The Conversion Chart provides a series of simplied mathematical formulas to “correct” the graduated scale for changes in pressure (Table 1), temperature (Table 2), and/or specic gravity (Table 3).

Special scales can be made to accommodate other pressures, temperatures and specic gravity.

The conversion chart can also be used to “correct” (adjust) the Multipressure Flow Scale to indicate ow rates in applications beyond the parameters stated on the scale.

for petroleum-based meters

Page 16 Form #04-VAM-UM-00229 09/12

To adjust Pressures beyond

(above or below) scale limits:

Step 1. Locate point at which the

brightly colored indicator line intersects the vertical 100 PSIG pressure line.

Step 2. Divide this reading by the Pressure Correction Factor (f1) indicated in the Conversion Chart.

To adjust for changes

in Temperature :

Step 1. Divide the 100 PSIG ow

rate reading by the Temperature Correction Factor (f2).

To adjust for changes

in Specic Gravity:

Step 1. Establish the square root of

the new specic gravity.

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