FTB700-Series
Inline Turbine Meters
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

of single piece casting stainless. Turbine rotors on all models are Kynar (PVDF).
FTB700-Series meters can be or dered with various output options. The basic model (FTB700) comes with pulse output only. An electronics module FTB700-D can be mounted to display flow rate and total (resettable or non-resettable), and provide a programmable pulse or 4-20 mA output. The FTB700-T is a blind 4-20 mA transmitter. All of these controls/displays can be mounted on the meter or remotely mounted on a wall or panel up to 2,000 feet away.

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
See Connection Diagrams and Operating Instructions for FTB700-D (rate/total display) or FTB700-T (blind analog transmitter) on following pages.

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.
