GENERAL INFORMATION and SPECIFICATIONS
GENERAL INFORMATION
This unique system of 2" to 8" turbine meters uses just one moving part, a precision helical rotor. Rotation of the rotor is electronically detected and processed. The high-quality jewel bearings and polished zirconia ceramic shafts minimize friction while providing long wear life in non-lubricating fluids. The entire rotor assembly can be easily removed for field service without removing the meter from the pipe.
FTB700-P bodies are fabricated from Schedule 80 PVC fittings, and FTB700-C bodies from carbon steel tubing. The FTB700-S meter (available as special order only) is fabricated from stainless steel tubing, with a turbine insert

INSTALLATION
CAUTION: These water meters are not
recommended for installation downstream of the boiler feedwater pump where instal­lation fault may expose the meter to boiler pressure and temperature. Maximum rec-
ommended temperature is 120˚ (PVC) or 200˚ (Metal).
Piping Conditions. Installing the meter with 10 diameters of straight pipe upstream and 5 downstream is recom­mended.
FTB700-P
Flanges. For 3-8” FTB700-C and -S meters, standard
flanges are 150 lb. ANSI drilling. 2” FTB700-C or -S meters and all FTB700-P meters can be installed with optional flanges according to pipe manufacturer’s recommendations. For FTB700-P a bolt torque of 10-20 ft-lbs. for 2” flanges, 20-30 ft-lbs. for 3” and 4” flanges, and 35-50 ft-lbs. for 6” flanges is recommended.
Either partial or full-face gaskets can be used. Tighten the bolts evenly. Use care to prevent a misaligned gasket from entering the flow stream.
Position. The FTB700-Series are all-position meters, oper­able in a ver tical or horizontal position, with the meter insert in any radial position. A horizontal position is preferred if there is a risk of air becoming trapped due to constant low flows. Operating the meter in partially-filled pipe will result in inaccuracies.
CONNECTIONS

MAINTENANCE and REPAIR
Recalibration. If it is necessary to recalibrate the meter
for any reason, please contact Omega.
Turbine Insert Removal and Installation. First remove all pressure from the line. Then remove the screws that hold the insert in place (or the U-clip in the 2” meters) and tug gently until the insert comes free. A twisting motion can help to loosen the O-ring seal. Reverse the procedure to reinstall, after coating the O-ring with a plastics-compatible lubricant. Do not over tighten the screws. Snug tightening with a hand screwdriver is sufficient.
Rotor and Shaft Replacement. Examine the rotor to deter­mine if bearings or shaft are damaged or excessively worn. The rotor should spin smoothly and freely, with no visible wobble. Back and forth play should be very minor, less than 1/64”. If it is necessary to replace the rotor or shafts, first back out both shafts with a small blade screwdriver. The rotor will come free as soon as the shaft ends come free of the rotor bearings. Reverse the procedure to reinstall. Note: Do not over tighten the shaft screws. Check to be sure that a small amount of free play between the shaft ends and the bearings remains.
Sensor Replacement. This is rarely necessary. However, certain electrical conditions can damage the sensor. To replace it, first remove the electronics module. Disconnect the sensor leads from the electronics module terminals and remove the threaded plug over the sensor. Finally, remove the sensor by pulling on the sensor leads. A gentle tug should be sufficient. Reverse the process to replace the sensor.

FTB700-D FLOW COMPUTER INSTRUCTIONS
GENERAL INFORMATION
The FTB700-D is a loop-powered microcontroller-based transmitter/indicator. It displays rate and total, and provides a 4-20 mA analog signal proportional to flow. A programmable pulse output, high flow or low flow alarm are also standard for metering pump control or data logging.
The rugged cast-aluminum housing is gasketed for maxi­mum environmental protection, and the electronics are potted into a solid block of urethane. A membrane key­pad allows settings to be changed without removing the cover. The wall mount version comes with brackets for mounting.

Wall Mounting. To mount the FTB700-D on a wall, hold the unit in the desired position, mark the holes in the mounting feet, drill, and mount with screws.
CONNECTIONS
See Connections Diagram for FTB700-D, next page.
Caution: If output is being used to control an external device, such as a metering pump, do not connect the de­vice until programming is completed. If malfunction or incorrect programming of
the output could cause personal injury or property damage, separate safeguards must be installed to prevent such injury or damage.
K-FACTOR
At a minimum, every FTB700-D flow computer must be programmed with the “K-factor”. (This is the number of pulses that the meter produces per gallon of flow.) If you wish the to read in units other than gallons, see below.
SETTINGS Set K. Begin by pressing the SET key once. The prompt SET
K should appear on the display. The digit to the far right will be blinking. Use the up arrow key to reach your desired value. Then press the left arrow key to move to the next digit. Repeat the process until the entire number is entered. (Note that the decimal is fixed at three places. If you only have two decimal places for your K-factor, enter a zero for the third digit.) Press SET to advance.
Set P/Flow Alarm. At this screen you may select between pulse output (P) or flow alarm (A) functions. If the pulse output and flow alarm features are not being used, this step can be skipped. The P (pulse output) setting does not affect anything if it is not being used.
Set P is the default that appears on a new FTB700-D. On a unit that has been previously set up with flow alarm function, an A will appear on this screen. To move between P and A screens, firmly press all three keys for 5-10 seconds, then use the up arrow to scroll through the three options: P, AL HI (high flow alarm) and AL LO (low flow alarm).
Set P. From this screen, follow the same process as for Set K to enter the desired pulse rate. This is the number of gal­lons (or whatever units are programmed) between pulses. (Note: Using the pulse output function disables the high and low flow alarm functions.)
Set Flow Alarm. From the A screen, use the up arrow key to choose either AL HI or AL LO and then press the SET key to set the alarm rate. Use the up arrow and left arrow as above to reach the desired digits. (Note: Using the flow alarm function disables the pulse output function.)
The K-factor can be found on the model-serial label. The line reading K = xxxx gives the desired number.
READING IN OTHER UNITS Changing Volume Units. The default K-factor units are
pulses per gallon. To read your total in metric or other units instead, the standard K-factor must be converted to the desired volume units. For example, to read in pulses per liter, the K-factor must be multiplied by the applicable number shown below.
NOTE: Both rate & total will read in whatever units you choose.
To Convert K to: Multiply by:
Liters .26418
Cubic Meters 264.18
Fluid Ounces .0078
Cubic Feet 7.48
Changing Time Units: To read your rate in liters per sec­ond (for example), convert the K-factor volume units as shown above and change the time units to Seconds, using the Set Time Unit instructions at right.
Set 20 mA. Press the SET key to advance to SET 20, to set the flow rate, in volume units per time unit, at which 20 mA is desired. Use the up arrow key to reach your desired value. Then press the left arrow key to move to the next digit. Repeat the process until the entire number is entered. The processor will automatically scale the 4-20 mA loop accordingly, with 4 mA at zero flow.
Set Decimal Point. Press the SET key again for the D prompt. Pressing the up arrow key switches among no decimal place, one decimal place and two decimal places.
Set Time Unit. When the SET key is pressed again, a blinking time unit appears. Press the up arrow key to select SEC (seconds), MIN (minutes), HR (hours) or DAY (days) (for example, gal/min, or gal/hr).
To return to normal operation after entering settings, press SET again. When the unit is connected to an operating flow sensor, the rate (larger digits) and total (smaller digits) indica­tor numbers should appear in the display.

Operation of 4-20 mA Output. If the 4-20 mA output is in use
and is correctly connected, the signal should vary between 4 mA and 20 mA in proportion to the flow, with the top flow rate set by the user. At no time should the signal drop below 4 mA. A reading between 0 and 4 mA indicates a fault of some type, typically in the loop power supply or the connections (see Troubleshooting). In the rare instance that the 4-20 signal fluctuates excessively (“paints”) it may need to be damped by additional averaging. Contact Omega for information on how to increase filtering.
Operation of the Pulse Output. If the pulse output is being used, it should pulse for 0.1 second every time the set num­ber of gallons has been totalized. If a pulse-responsive meter­ing pump is properly connected to this output, it should stroke periodically. If this does not occur, see Troubleshooting.

GENERAL INFORMATION
The Omega FTB700-T is a blind (non-indicating) 4-20 mA transmitter. It accepts a pulse frequency input from the flow sensor, and conver ts this input into a continuous analog output signal. Power for the transmitter is taken from the current loop itself, so only two wires are required. The digital design makes it possible to span the unit in the field without tools. The frequency at which 20 mA is desired is entered on a set of rotary switches, and an internal microcontroller au­tomatically scales all other values accordingly. An additional benefit of the microcontroller is its ability to average inputs, for smoothing of the output signal. The degree of averaging can be selected in the field, from 2 to 16 seconds.
For maximum environmental protection, the electronic com­ponents are encased in a special semi-flexible urethane potting material. The housing is cast from aluminum and fuse-coated. The clamshell housing is provided with mount­ing feet for remote mounting.
The FTB700-T will operate on a relatively wide range of cur­rent loop voltages, 24 to 36 Vdc. Lower voltages limit the load that can be applied to the loop without distortion of the signal. (See Load/Supply chart below if there is a question regarding voltage vs. load.) A built-in power regulator sup­plies the appropriate power to the flow sensor.

INSTALLATION
Wall Mounting. The FTB700-T comes with mounting
feet and requires four screws to attach it to any stable surface.
Connection. The upper por tion of the housing must be removed to make connections. Use a standard hex wrench (5/32” or 4 mm) to loosen the screws, then remove the upper half. The connections are made to terminal blocks in the upper half, which contains the potted electronics. The terminal blocks are removable and can be unplugged and plugged back in for convenience.
Consult the FTB700-T Connections Diagram before connecting to the current loop and flow sensor. Be careful to follow the color coding of the flow sensor wires in order to establish the correct polarity. Incorrect polarity can damage the sensor.
Caution: If output is being used to control an external device, such as a metering pump, do not connect the de­vice until programming is completed. If malfunction or incorrect programming of
the output could cause personal injury or property damage, separate safeguards must be installed to prevent such injury or damage.
SETTINGS
Setting Frequency. The FTB700-T converts a train of off/on
pulses from the flow sensor into a continuous milliAmp signal that ranges from 4 mA at zero flow to 20 mA at the desired maximum flow. The desired maximum is determined by the user and entered as a frequency as follows:
1)
Decide what flow rate should represent the top of the scale. This is ordinarily the maximum expected flow, or a value just above it, in gallons per minute.
2)
Locate the K-factor of the flow sensor (found on the Serial Number label on your meter). K-factor is the number of pulses the flow sensor produces per gallon of flow.
3)
Calculate frequency, using this formula:
K-Factor x Top Flow (GPM) = Frequency 60
4)
Enter the frequency using the four rotary Frequency switches. Note the decimal point between the third and fourth switches.
SETTING FREQUENCY EXAMPLE
In an installation with an estimated maximun flow rate
1) of about 150 GPM, a flow rate of 170 GPM is selected as the full-scale maximum, the flow at which the current loop will register 20 mA.
In this example, "K = 54.50". (In your actual ap-
2) plication, look for the K-factor on the Serial Number label on your meter.)
Calculate the frequency as
3)
54.50 x 170 60
4)
Rounding to one decimal point, enter 154.4 on the
= 154.42
rotary switches by turning the rotary switch pointer to the desired digit.

Setting Averaging Time. For most applications, this step can be ignored, as the standard setting will work fine. However, when a particularly steady output signal is desired, or in large pipe, a larger averaging period may be desirable. Note however that the averaging period requires a tradeoff, since a longer averaging period implies a slower response time. If steady signal is more impor tant than fast response, increase the averaging time as desired. See the diagram below for the switch positions and their corresponding times.

Checking Calibration
Normally it should not be necessar y to check calibration, since the digital design of this unit virtually eliminates drift. However, there are two types of calibration check that can be performed. Look at the diagram below to locate the 4 and 20 mA force switches. To force the 4 mA output, put its switch in the up position. Check the current output at the Power terminals, and if necessary trim to 4.00 mA using the appropriate trimpot. Return the switch to the down position, and repeat the process with the 20 mA switch.

Problem
No analog signal at reading device
Output stuck at 4 mA
mA signal does not match flow rate
Probable Cause Try...
Break in current loop Dead power supply Reversed polarity
No frequency input from flow sensor
Inadequate voltage Wrong frequency setting
Check if loop indicator light is on Check multimeter voltage on power supply Check polarity
Check flow sensor connections Check flow sensor polarity Be sure terminal blocks are firmly plugged in With flow sensor disconnected, use short wire to repeatedly short between sensor “S” and “-” terminals. Output should rise.
