Installation & Maintenance Instructions

I. INTRODUCTION

The FL9000 series ﬂ ow meter is a rugged, low-cost direct reading industrial class ﬂ ow meter that is simple to install. It can be mounted (installed) in any position from vertical to horizontal without costly ﬂ ow straighteners or other special plumbing. Constructed of high impact polysulfone plastic, the FL9000 product line offers excellent structural integrity and chemical compatibility with a wide range of industrial chemicals.

FL9000 ﬂ ow meters provide instantaneous, direct-reading ﬂ ow rate measurement of liquids in closed piping systems. The transparent polysulfone plastic body allows visual inspection of the ﬂ uid condition as well as viewing of the internal ﬂ ow indicator relative to a calibrated ﬂ ow scale. See

Figure 1.

FL9000 meters do not require electrical connections for operation, and provide measurement by creating a predictable differential pressure across a sharpedged oriﬁ ce that is located in the piston assembly.

II. OPERATING PRINCIPLE

The FL9000 series ﬂ ow meter is a piston- type variable area ﬂ ow meter that uses a sharp-edged annular oriﬁ ce, formed between an open-centered piston and a tapered metering cone. The piston is held in a “no-ﬂ ow” position at the base of the cone by a precision retention spring. As ﬂ ow in the pipe increases, the differential pressure correspondingly increases across the piston oriﬁ ce, and moves the piston/ ﬂ ow indicator against the spring. The greater the ﬂ ow rate, the further the piston moves along the tapered metering cone. The ﬂ ow rate is measured by viewing the red indicator ring, mounted on the piston,

relative to a graduated ﬂ ow scale located on the transparent ﬂ ow meter body. See

Figure 2.

The unique design allows the FL9000 meter to be mounted in any orientation– horizontal, vertical, upside down, etc.–without sacriﬁ cing measurement performance. Flow straighteners, located in the inlet and outlet, allow the ﬂ ow meter to be less sensitive to turbulent ﬂ ow conditions. Liquid measurements are provided in GPM (Gallons per Minute) and LPM (Liters per Minute).

Installation & Maintenance Instructions

IV. INSTALLATION

CAUTION

This unit should be installed and serviced by technically qualiﬁ ed personnel trained in maintaining industrial class ﬂ ow instrumentation and processing equipment.

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.

Installation Recommendations

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

CAUTION

Liquid pipe sealants, PVC/CPVC primers and PVC/CPVC cements contain solvents that are not compatible with polysulfone plastic. Allowing liquid pipe sealants to contact the plastic ﬂ ow meter will result in weakening of the ﬂ ow meter body and potentially cause fracturing under pressure.

Don’t - Allow liquid pipe sealant, PVC/

CPVC primer or PVC/CPVC cements to come into contact with the plastic ﬂ ow meter. These contain solvents that are not compatible with polysulfone plastic and will result in the ﬂ ow meter body weakening and potentially fracturing under pressure. If a pipe sealant is required, use of Teﬂ on is recommended.

Don’t - Install the ﬂ ow meter in piping

systems that are not aligned or properly supported.

Don’t - Connect the ﬂ ow meter male plastic

tape

NPT ﬁ ttings to female metal NPT couplings. Differences in coefﬁ cients of expansion between metals and plastics can cause the plastic ﬂ ow meter body to crack. Utilize a female-to- female plastic pipe coupling to connect metal pipe to the plastic ﬂ ow meter.

Don’t - Use pipe wrenches on the ﬂ ow

meter body. To avoid scarring or otherwise damaging the external surface, use an open-end wrench on the integral hex ﬂ ats during installation.

Don’t - Subject the ﬂ ow meter to back

pressure or back ﬂ ow. The ﬂ ow meter will operate as a “leaky” check valve when subjected to reverse ﬂ ow, but can be damaged if the reverse hydraulic horsepower is too great.

Don’t - Install the ﬂ ow meter on systems with

large degrees of particulate contamination. Minimum ﬁ ltration of 200 mesh (74 micron) is recommended for trouble-free operation.

Don’t - Install O-ring seals that have not

been lubricated.

Piping (Plumbing)

CAUTION

To avoid unnecessary pipe ﬂ exing that could cause structural stress on the ﬂ ow meter body, independent support located as near as possible to the inlet and outlet of the meter should be used to isolate the meter from the piping system. Failure to provide this support could reduce the life of the meter.

Piping should be properly aligned with the meter inlet and outlet to minimize structural stress on the plastic meter body. Special attention should be given to this effort if higher operational pressures and/or temperatures are anticipated. Piping should be ﬁ rmly supported by external mounting brackets, both upstream and downstream from the meter to avoid any pipe ﬂ exing that could reduce the life of the meter.

1. If the ﬂ ow meter inlet or outlet are to be

Page 5

Page 6

Installation & Maintenance Instructions

rigidly mounted, and the opposing port is to be connected to a ﬂ exible hose, the end connected to the ﬂ exible hose MUST be rigidly mounted.

2. This unique design does not require special plumbing or accessories to stabilize turbulent ﬂ ow. Flow meters can be installed immediately adjacent to 90° elbows or other components, providing system design ﬂ exibility.

3. A 200 mesh (74 micron) or better ﬁ ltration is required to assure reliable performance.

Flow Direction

These meters only accept ﬂ ow in one direction. Make sure to align the Flow Arrow, located on the bottom of the meter’s ﬂ ow scale, in the same direction as the

anticipated line ﬂ ow. See Figure 3.

Mounting Orientation

The meter can be installed to operate in any position.

1" NPT Models (See Figure 4)

1. Apply a single layer of Teﬂ on® tape to the male NPT threads of the ﬂ ow meter.

2. Thread the ﬂ ow meter inlet into a 1" NPT plastic, female pipe coupling.

V. FLOW-ALERT SWITCH OPTIONS

NOTE: All Flow-Alert switches are magnetically triggered. It is not possible to add a switch to the basic meter if it was not originally ordered with the switching magnet.

Flow-Alert Latching Limit Switch

The AC and DC powered Flow-Alert modules consist of a relay circuit housed in a sealed plastic enclosure. The modules have a normally open, dry relay contact that can be used to directly control alarms, warning lights, relays, or interface to a PLC. The relay will be latched on as the magnet inside the ﬂ ow meter passes by the module, and remain latched on until the magnet passes in the other direction, or power is

interrupted. See Figure 9. The setpoint is

adjustable from 0-100% of full scale. Flow meters can be equipped with one latching limit switch, either AC or DC.

Installation & Maintenance Instructions

VI. MAINTENANCE

FL9000 Flow Meters are designed to provide many years of service with little or no maintenance requirements. Periodic cleaning may be required.

• Clean the outside of the ﬂ ow meter with denatured alcohol or mild detergent and warm water.

• Should the inside of the ﬂ ow meter become stained, it can be disassembled for cleaning.

• Should the ﬂ ow meter become jammed with particulate, the meter will require disassembly as described below. The piston assembly should be pushed out from the inlet side to the outlet side. Clean the internal components and reassemble.

Disassembly

NOTE: Models with a 1" body-it is necessary to remove the spring retaining clip (located at the ﬂ ow meter outlet port).

NOTE: Models with a 2" body can be serviced by removing the two end ﬁ ttings, then sliding the metering pin out from the inlet, and removing the piston and spring from the outlet.

1. Measure the insertion depth of the retaining ring into the ﬂ ow meter body with a caliper or other measuring device.

2. Carefully remove the retaining clip with a small, ﬂ athead screwdriver.

3. Remove the spring and piston assembly.

4. Clean the inside of the ﬂ ow meter body and piston assembly with denatured alcohol or mild detergent and water.

5. Reassemble the meter in reverse order of disassembly. Install the retaining ring to the depth measured in step 1. Use a deep socket of approximately 0.9" diameter and hand pressure to install the retaining ring.

VI. APPENDIX

Fluid Correction Standard Flow Scales

Standard liquid ﬂ ow scales are calibrated in GPM (Gallons per Minute) and LPM (Liters per Minute) at 0.876 speciﬁ c gravity for petroleum-based ﬂ uids, and 1.0 speciﬁ c gravity for water and water-based ﬂ uids.

For ﬁ eld conversion of the standard scale to

other ﬂ uids, see Density Effect below.

Special Flow Scales

Special scales are available for liquids in any measurement unit, and other ﬂ uid viscosities and/or speciﬁ c gravities.

Viscosity Effect (SS/cSt)

The design utilizes a sharp-edged oriﬁ ce and biasing calibration spring that ensures operating stability and accuracy over the wide viscosity range common to many ﬂ uids. Generally, high ﬂ ow models of each meter size provide good accuracy over a viscosity range of 40 to 500 SUS (4.2 to 108 cSt).

Density Effect (Speciﬁ c Gravity)

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

NOTE: The pressure drop curves are valid for ﬂ uids with density and viscosity similar to factory test ﬂ uids. Fluids, especially with higher viscosity than these test ﬂ uids, will yield a higher pressure drop through the ﬂ ow meter and piping system per a given ﬂ ow volume.

Note: A system must have adequate ﬂ uidic horsepower available to move the system ﬂ uid at a prescribed rate at a pressure adequate to overcome all pressure reducing devices

- including the ﬂ ow meter.
