FTB-1300 Series Turbine Flow Meter

General Description:

The FTB-1300 series of turbine flow
meters is designed with a wear resistant
rotor assembly to provide trouble free
operation and a long service life. Fluid
moving through the flow meter causes the
rotor to turn at a speed proportional to the
flow rate, and as the rotor blades cut
through the magnetic field of the pickup,
an electronic pulse is generated.

The pulse train is used to represent the
actual flow or total amount of fluid passing
through the flow meter. The number of
electronic pulses generated per unit
volume is known as a K-factor. The value
is constant over each flow meter's
operating range, and is unique to each
meter.

Operating Limitations of the FTB-1300 Series Turbine Flow Meters

:

1) Pressure - 5,000 PSI max

WARNING: Pressure in excess of allowable rating may cause the housing to burst and cause

serious personal injury.

2) Corrosion - The internal parts of the meter are constructed of stainless steel (316L & 1.4122) and
carbide with nickel binder. Be sure that the operating fluid is compatible with these materials.
Incompatible fluids will deteriorate internal parts, and cause the meter to read inaccurately.

3) Pulsation - Severe pulsation will affect accuracy, and shorten the life of your meter.

4) Vibration & Shock - Severe mechanical vibration may decrease service life of the meter.

5) Filtration - A strainer should be installed upstream of the meter if small particles are present (see
Table 1 for filtration requirements)

Installation Instructions:

Before installation, the flow meter should be checked internally for foreign material and to ensure that
the rotor spins freely. Fluid lines should also be cleared of all debris.

Warning: Make sure that fluid flow has been shut off and pressure in the line released before
attempting to install the meter in an existing system.

The flow meter must be installed with the flow indication arrow, etched on the exterior of the meter body,
pointing in the correct direction of flow. The preferred mounting orientation is to have the meter installed
in horizontal piping, with the pickup facing upward. However, the meter will function in any position.

The liquid that is to be measured must be free from any large particles that may obstruct rotation of the
rotor. If particles are present, a mesh strainer should be installed upstream before operation of the flow
meter. (See Table 1)

Table 1

Note: Select appropriate strainer for your turbine model by your turbine part number.

The preferred plumbing setup is one containing a bypass line that allows meter inspection and repair
without interrupting flow. If a bypass line is not utilized, it is important that all control valves be located
downstream of the flow meter.

It is recommended that a minimum length, equal to ten (10) pipe diameters of straight pipe be installed
on the upstream side and five (5) diameters on the downstream side of the flow meter. Otherwise meter
accuracy may be affected. Piping should be the same size as the meter bore or the thread port size.

Do not locate the flow meter or the connection cable close to electric motors, transformers, sparking
devices, high voltage lines or place connecting cable in conduit with wire furnishing power for such
devices. These devices can induce false signals in the flow meter coil or cable, causing the meter to read
inaccurately.

Operational Start Up:

The following practices should be observed when installing and starting the meter.

1) After meter installation, close the isolation valves, and open the bypass valve. Flow liquid through the
bypass valve for sufficient time to eliminate any air or gas in the flow line.

Caution: Damage can be caused by striking an empty meter with a high velocity flow

stream.

2) Open upstream isolating to eliminate hydraulic shock while charging the meter with the liquid. Open
the valve to full open.

3) Open downstream isolating valve to permit meter to operate.

4) Close the bypass valve to a full closed position.

5) Adjust the downstream valve to provide the required flow rate through the meter.

NOTE: the downstream valve may be used as a control valve.

If problems arise with the flow meter, consult the Trouble Shooting Guide (Appendix A). If further prob­lems arise, consult the factory. Turbine meter repair kits are also available. See appendix B & C.

FTB-1301 to FTB-1308 Hall Effect Pickup

Installation and Technical Data Guide

Description:

The FTB-1301 - 1308 Hall Effect sensors are compatible with Positive Displacement gear flow meters
and turbine flow meters. The sensor detects the rotation of the flow meter’s gears and emits a fre­quency signal proportional to flow. The output signal is a square wave pulse which has a duty cycle of
approximately 50%.

Signal outputs are protected with a self-resetting fuse. This fuse has a 50mA nominal trip point. When
a trip occurs, turn off power to the sensor and remove output load to reset fuse.

Installation:

• Ensure that the flowmeter sensor cavity is free of debris prior to installing pickup

• Swivel fitting is required for sensor mounting. Note: In order to recieve correct swivel fitting with your
sensor - you must specify meter part number when ordering

• 4 Steps to properly install sensor:

1- Securely fasten swivel fitting on flow meter
2- Turn set screws counter clockwise until they are not visible inside the swivel fitting
3- Install sensor into swivel fitting until sensor bottoms out in the sensor hole
4- Tighten set screws by turning clockwise

NOTE: DO NOT OVER TIGHTEN SET SCREWS OR SENSOR DAMAGE WILL OCCUR!

Scaling Analog Output:

On the front panel there are four rotary switches which are
adjustable with a small screwdriver. It is not necessary to
power the unit down to change the settings. The switches are
read from left to right in order of decreasing value as shown in
the figure to the right.

If the maximum frequency is known at which the resulting output should be 20mA, set the switches to
this frequency. The output will automatically scale itself. If the maximum frequency is not known, the correct

switch settings can be determined in 2 ways.
The following equation can be used to determine what the switch setting should be for any particular meter and

flow rate.

Switch Setting =

Where: K Factor is the flow meter scaling factor in pulses / volume (found on calibration sheet)
Max. Flow Rate is the flow rate at which the analog output should be at it's max.
Note: K-Factor and Max flow rate MUST have same units, ie: gallon/GPM, liter/LPM
60 is the scaling factor when max. flow rate is in volume/minute. Use 3600 for volume/hour

Ex: K Factor = 89,100 pulses/gallon (for a FTB-1301), Max flow rate = 0.2 GPM
Switch Setting = = 297

If the numerical flow rate is not known, the unit can be calibrated in systems with the following:

1) Adjust system flow to the rate at which analog output should read 20 mA.

2) Set scaling switches to a value known to be above the maximum frequency (ex. 9, 49, 799, 2999) if unsure,
use 4999

3) If S1 is 0, go to step 4. Decrease S1 until output shows 20 mA. Then increase its setting by one unless value
is 4, in which case value should remain 4. If the switch value is 0 and the output is below 20 mA, leave switch
at 0 and go to next switch.

4) If S2 is 0, go to step 5. Decrease S2 until output shows 20 mA. Then increase its setting by one unless value
is 9, in which case value should remain 9. If the switch value is 0 and the output is below 20 mA, leave switch
at 0 and go to next switch.

5) If S3 is 0, go to step 6. Decrease S3 until output shows 20 mA. Then increase its setting by one unless value
is 9, in which case value should remain 9. If the switch value is 0 and the output is below 20 mA, leave switch
at 0 and go to next switch.

6) Decrease S4 until output shows 20 mA and leave setting. DO NOT increase this setting by one. The switches
are now set at the frequency which will result in a 20 mA output.

When setting switches in step 1, try to use numbers ending in 9 for example: 9, 39, 299 and 2999. Any switch
setting above 5000 Hz is read as 4999 Hz.

Example: Actual maximum input frequency is 538 Hz. Switches are set to 0999 Hz, a value known to be above
actual maximum input frequency. The output shows 12.64 mA.

Starting with the switch of highest order, in this case S2 since S1 is 0, its value is decreased until the output
shows 20 mA (S2 shows 4). The switch is then increased by 1 (S2 is set to 5). S3 is then decreased until the
output shows 20 mA (S3 shows 2). The switch is then increased by 1 (S3 is set to 3). Finally, S4 is decreased
until the output shows 20 mA and left as such (S4 set at 8) the switches are now set to 538 Hz, the frequency
which will cause maximum output current / voltage.
