The oval rotor principle has proven to be a reliable and highly accurate method of measuring flow. Along with the smooth oval rotors, exceptional repeatability and high accuracy over a wide range of viscosities and flow rates are features of the FTB3000 Series flow meter design.The low pressure drop and high pressure rating means the Omega FTB3000 Series flow meter is suitable for both gravity and pump (in line) applications.Please take a few minutes to read through this manual before installing and operating your meter. If you have any problems with the meter, refer to the maintenance and troubleshooting sections of this manual.If you need further assistance, contact Omega’s customer service department by telephone or fax for advice.2.SpecificationsService Fluids: Clean liquids, max particle size .125" Accuracy: ± 0.25% of reading or better above 100 cstk Repeatability:± 0.05%Flow Range:w/ Mag Coil Pickup 2 to 20 GPMw/ Hall Effect Pickup 0.02 to 20 GPMK-factor: 460 pulses per gallon (approximate)Operating Temperature:w/ Mag Coil Pickup: -268°C to +232°C (-450°F to +450°F)w/ Hall Effect Pickup: -40°C to +150°C (-40°F to +302°F)Operating Pressure: 3000 PSIG standardMinimum Fluid Viscosity: 100 cstkWetted Parts: 316 SS body and gears with peek gear seats Bearings: Shielded, self lubricating 440 SS ball bearings Connections:Flange Option: 1" MNPT STDPickup Coil: Magnetic Type or Hall Effect (6 to 24 vdc power) Calibration: 10-point calibration traceable to NIST @ 100 cstks3.Operation3.1PrincipleThe FTB3000 Series of positive displacement meters use a pair of smooth oval rotors to provide a reliable and highly accurate measurement of flow. The smooth oval rotors displace a precise volume of fluid which is passed through the measurement chamber during each revolution. The smooth oval rotor design along with the viscosity of the fluid provides a complete viscous seal within the measurement chamber.The unique patented design ofOmega’s Oval Gear meterincorporates two smooth ovalrotors 90 degrees out of phase.The phase relationship of therotors is maintained by twooval timing gears which areout of the flow path. The ovaltiming gears have a pitchdiameter equal to the outsidediameter of the smooth oval rotors.The flow through the meter measurement chamber follows the path of least resistance. Therefore no liquid passes through the center cavity between the rotors. The fluid is displaced from the inlet to the outlet via the area between the smooth oval rotors and the inner diameter of the meter housing.3.2Precautions▪Before use, confirm the fluid to be used is compatible with the meter and make certain that the operating conditions conform to the meter specifications.▪To prevent damage to the meter slowly fill the system with fluid (this will prevent damage that may be caused by air purge).▪Keep the flowrate within the meter ratings.▪Remove meter from the piping, replacing with a short pipe, when cleaning the piping system by flushing. Costly damage to the meter may result if the assembly is cleaned by flushing with the meter installed.4.Installation▪Use thread sealant on all pipe threads.▪Install the meter carefully to avoid pipe strains.▪The meter must be installed on the discharge side of the pump.▪In tank-head operation, the head of the fluid must be higher than the pressure loss of the meter.▪The flow direction must conform to the arrow mark on the meter body.▪The meter must be installed in the correct orientation (see figure below).▪Connect appropriate connector from pick-up from DCS or electronics.Pickup ConnectionsStandard MAGHall Effect(Open Collector) Redi-Pulse(Open Collector)A - Signal (+)B - Common (-)A - 8 - 30 Vdc (+)B - Common (-)C - Pulse OutputA - 3.5 - 24 Vdc (+)B - Common (-)C - Pulse Output5.Maintenance5.1GeneralThe Omega FTB3000 Series flowmeters do not require routine maintenance and do not contain any field serviceable or replaceableparts.5.2Trouble ShootingRefer to the following troubleshooting guide for assistance withpossible meter malfunctions:TROUBLE CAUSE REMEDYFluid will not flow through the meter ▪Meter installedwith incorrectorientation.Re-orientate the meter.▪Line to meterblocked.Clear line to meter.▪Insufficientdifferentialpressure.Increase upstreampressure.Reduced flow through the meter ▪Line to meterpartially blocked.Clear line to meter. ▪Insufficientdifferentialpressure.Increase upstreampressure.Meter readings inaccurate ▪Fluid flowrate istoo low.See “Specifications” formin and max flowrates. ▪Fluid viscosity toolow.Check fluidspecifications.▪Air in fluid.

Their small size and standard 3⁄4 NPT fittings make them suitable for new or existing applications. The LVU-230 models have a relay output along with a 316 SS or PVDF sensor and an integral miniaturized, encapsulated electronic control unit mounted in a cast aluminum, explosion-proof, watertight enclosure. The LVU-260 is a 2-wire, 4 or 20 mA output system.Both use an ultrasonic wave propagation sensor mounted in the liquid medium. The electronics generates a continuous wave ultrasonic signal that completely illuminates the liquid-sensing area. The absence of liquid in the sensing area causes the ultrasonic signal to dissipate, which the electronics senses as a “dry” condition (and provides a 4 mA output signal in the LVU-260). When liquid is present, the amplitude of the ultrasonic signal increases, indicating a “wet” condition. This signal is converted by the electronics and energizes the 10 A relay (LVU-230) or a 20 mA output signal (LVU-260). The LVU-230 electronics may be set to provide the control output to an alarm, pump, or other device on either a dry or wet condition.SPECIFICATIoNS Repeatability: 2 mm (0.08") typical Delay (on): 0.5 s Input Power: LVU-230: 115 Vac 50/60 Hz standard; 230 Vac 12 Vdc, or 24 Vdc (optional) LVU-260: 9 to 36 Vdc outputs: LVU-230: 10 A DPDT LVU-260: Low-level fail-safe: 4 ±1 mA dry; 20 ±1 mA wet; high level: 20 ±1 dry, 4 ±1 wet ¾ NPT THREAD Ultrasonic liqUid level switchesLVU-230S, shown smaller than actual size.Housing: NEMA 4/NEMA 7 watertight, explosion-proof enclosure, cast aluminum Class I, Group C and D, Class II, Groups E, F and G; and Class III, Division I and 2Sensor Material: L VU-230S, L VU-260S: 316 L SS L VU-230K, L VU-260K: PVDF Temperature: Sensor: -40 to 149°C (-40 to 300°F) Electronics: -29 to 77°C (-20 to 170°F)operating Pressure: Up to 1000 psig Mounting: 3⁄4 NPT standard Weight:453 g (1 lb)。

If you have any problems with the meter, refer to the maintenance and troubleshooting sections of this manual.If you need further assistance, contact your local Omega Representative or contact the Omega customer service department by telephone, fax, or email for advice.2Operation2.1PrincipleThe Omega FTB500 Series of Low Flowrate Meters has been developed to meet the need for a low flow measurement device for use with low to moderate viscosity clean liquids and for gas measurement applications.The Omega FTB500 Series of Low Flowrate Meters is a family of low flow rate measurement devices whose design is based on a Pelton Wheel-like rotor. The measured fluid is directed tangentially through a velocity nozzle against the rotor causing it to spin. The pickup coil senses the spinning motion of the rotor through the housing and converts it into a pulsing electrical signal. Summation of the pulsing electrical signal relates directly to the total flow, while the frequency is related to the flow rate.2.2Precautions♦Do not drop the meter. Dropping the meter may result in damage to the meter housing and/or internals.♦Do not operate the meter at flowrates greater than the maximum flowrate marked on the meter. Operating atflowrates greater than the maximum flowrate may over-spin the meter. Over-spinning may result in damage tothe meter.CAUTION:Avoid over-spinning the meter. Over-spinning the meter may result in damage to the meter internals and lead to meterfailure.3 InstallationUpon receipt of the flowmeter carefully inspected it, checking for any indications of damage which may have occurred during shipment. Inspect all packing material carefully for parts or components which may have been packed with the shipment. Refer to the packing list/invoice for a detailed list of items included in the shipment.3.1 General PipingThe Omega FTB500 Series of Low Flowrate Meters is capable of sensing fluid flow in one direction only. The meter housing is marked by a flow direction arrow to indicate the direction of flow through the meter. The meter must be installed in the piping in the correct orientation to ensure the most accurate and reliable operation. Care should be taken in the proper selection of the mating fittings. Size, type of material, and pressure rating should be the same as the flowmeter supplied.When it is expected that flow will be intermittent, the meter should not be mounted at a low point in the piping system. Solids which settle or congeal in the meter may affect meter performance.In order to achieve optimum electrical signal output from the flowmeter, due consideration must be given to its isolation from ambient electrical interference such as nearby motors, trans-formers, and solenoids.A typical flowmeter installation is shown below:Blocking and Bypass valves should be installed if it is necessary to do preventive maintenance on the flowmeter without shutting down the flow system. The Bypass valve can be opened before the Blocking valves are closed allowing the flow to continue while removing the turbine flowmeter for service.BYPASS RUN METER RUNIMPORTANT: All flow lines should be purged prior to installing themeter. To prevent possible damage to the meter, install themeter ONLY in flow lines that are clean and free of debris.Upon initial start-up of the system a spool piece should be installed in place of the flowmeter so that purging of the system can be performed to remove all particle debris which could cause damage to the meter internals. In applications where meter flushing is required after meter service, care should be taken as to not over-spin the meter, as severe meter damage may occur.CAUTION:Avoid over-spinning the meter. Over-spinning the meter may result in damage to the meter internals and lead to meterfailure.3.2Strainers/FiltersThe Omega FTB500 Series of Low Flowrate Meters is designed for use in a clean fluid service. However, the service fluid may carry some particulate material which would need to be removed before reaching the flowmeter. Under these conditions a strainer/filter may be required to reduce the potential hazard of fouling or damage that may be caused by foreign matter.METER SIZE MESH SIZE PARTICLE SIZE(Maximum)¼" to ½"100 .00555/" to 1¼"70 .00881½" to 3"40 .015If a strainer/filter is required in the system, it should be located upstream of the flowmeter taking care that the proper minimum distance is kept between the strainer and flowmeter.3.3Installation KitsInstallation kits for the Omega FTB500 Series of Low Flowrate Meters consist of two lengths of appropriate tubing cut to a length appropriate for the upstream and downstream straight pipe run with appropriate end fittings.4Maintenance4.1GeneralPreventive maintenance for the Omega FTB500 Series of LowFlowrate Meters consists of a thorough general inspection.Remove the meter from the service line and take to a clean workarea. Use the following procedures and exploded component views to remove, inspect, and reinsert the flowmeter internals.4.2Disassembly1.Hold the meter securely using a vise. Meter orientationshould be such that the threaded plug is facing up. Useextreme care not to damage the meter housing or pipingconnections when placing in the vise.ing a large-blade screwdriver, turn the plugcounterclockwise to remove.3.To remove the shaft assembly, carefully thread a 10-32screw into the hole provided in insert. Thread the screwinto the insert until it bottoms out (finger tight only).4.Turn the housing over and slowly and carefully pull theshaft assembly and internals out of the housing. Takecare not to damage the shaft, rotor, and/or bearings.5.Remove and discard the gasket/seal.4.3Inspection & Repair1.Examine the flowmeter internals for signs of corrosionor fouling by foreign materials.2.Examine the shaft, rotor, and bearings for signs of wearand/or damage.3.If wear or damage is present, replace with new parts.NOTE: Clean all of the internals in an approved cleaning solution.Exploded View: C – Hard Carbon Bearing ModelsExploded View: BB - Ball Bearing ModelsRotorRotor4.4 Assembly1.Install any new parts.2.Guide the rotor and bearing assembly onto the shaft.Make sure the rotor is installed with the cup side of thePelton wheel facing the “IN” side of the housing.3.Place a new gasket on the insert. Always use a newgasket.4.Place the shaft assembly insert, gasket, and rotorassembly back into housing by inverting the housing tokeep gasket and rotor assembly in place.5.Install the threaded plug and tighten to 50 ft-lb.4.5Pickup Coil TestingTesting the MAG and MCP (RF) coils consists of measuring the resistance with an ohmmeter. Resistance measurements are to be made when there is no flow through the meter or with the coil removed from the meter housing.1.Measure the resistance between pin A and pin B. Theresistance should be approximately as listed in thefollowing table of some common coils.2.The resistance from any pin to the case should be greaterthan 1 Mohm.COIL DC RESISTANCE(Ohms)MC2PAHT 15.0 ±10%MCP3A 11.5 ±10%PC13-74G 1800 ±10%PC13-74S 1850 ±15%PC24-45G 1350 ±10%PC24-45S 1850 ±15%PC28-13G 120 ±20%PC28-14G 180 ±20%If either resistance measurement fails, replace the pickup coil.
