The FTB-100 Series of turbine meters have a sealed ball bearing design for high accuracy performance (±½% of reading, not full scale) at an economical cost. The non-metallic bearing retainers minimize friction, thereby allowing these meters to be used with clean fluids that have poor lubricating properties ( i.e.water). Ball bearings also give the widest linear flow range, particularly in larger turbines. Bearing replacement and clean-up are fast and easy, since all internal parts are easily accessible by removing a single nut.
These turbine flowmeters have a low mass rotor design which allows rapid dynamic response, so they can be used in pulsating flow applications. Deflector cones eliminate downstream thrust on the rotor and allow hydrodynamic positioning of the rotor between the cones. This provides wider rangeability and longer bearing life than conventional turbine flowmeters. Integral flow-straightening tubes minimize the effects of upstream turbulence.
FTB-100 Turbine Meters are available with integral signal conditioners (as shown in photo) which provide scaled and unscaled frequencies, 4-20 mA, or 0-5 Volt outputs. Units without integral signal conditioners are supplied with mating connector for two-wire hook-up.

Viscosity affects the reading? I.e. a sensor calibrated for water will have same readings when used for oil with viscosity between 25 to 75 cSt (viscosity changing by oil temperature) ?
Thank you for your inquiry about the turbine flow meter. Yes, the viscosity affects the reading and the turbine flow meter is calibrated for water and if you have a viscous liquid to measure, then, it will need to be specifically calibrated for that liquid for an additional cost as noted on the data sheet. Please note, in the event the temperature changes so does the viscosity and therefore, the calibration will be affected as a result. Highly recommend a positive displacement flow meter such as the FPD3000 series.

1. Can the FLSC-C1-LIQ be mounted remotely from the FTB-101? Need to locate the signal conditioner away from the turbine meter due to high ambient temperature. 2. How is the FTB-101 wired-connector or pigtail? If pins, what connector is required?
Thank you for your inquiry. It is recommended not to separate the signal conditioner from the flow meter and in the event that it must, you can add 2-wire shielded cable from the 2 PINS of the turbine flow meter to reduce the electrical noise.

Is there somewhere I can download a 3D model of this flow meter?
Thank you for your inquiry and unfortunately, Omega does not provide CAD or STEP files for their products.

I need to connect the FTB-102 with a PLC. Can this flowmeter generate a 4-20mA or a DC signal or even a digital pulse output which can be read on the controller to monitor flow through the meter?
Thank you for your inquiring about this this flow meter. The FTB-100 series turbine flow meter self generates a sinusoidal wave and will need an amplifier such as the FLSC-AMP to amplify to a square pulse.

Are these good for zone 0?
Thank you for your inquiry in regard to the turbine flow meter. The FTB-100 series coupled with the signal conditioner identified in the data sheet is ATEX rated, without it, unfortunately, no.

Do any of the pins connect with the body of the flow meter or housing the signal conditioner sits in?
Thank you for your inquiry about this flow meter. The turbine flow meter and signal conditioner are recommended to be purchased as a 'SYS' or system and they are scaled together to be used when received.

If the system with the signal conditioner is rated for Zone 0, why does the datasheet say the signal conditioner is only rated for Zone 1 and 2? Thanks,
Thank you for your inquiry. The system is only rated for Zone 1 and 2, not Zone 0.

Do any of the electrical connections have an electrical connection with the housing? Is it isolated? I'm using with a piece of equipment that requires an SELV power supply and equipment. The housing will be PE grounded.
The self powered flow meter does not come with an electrical housing. The body of the flow meter needs to be grounded if used in a noisy environment.
