FTB600B Series Installation 1 IMPORTANT: READ INSTRUCTIONS THOROUGHLY BEFORE INSTALLING FLOW METER Section 1 - Introduction A. General Description The FTB600B Series is an axial paddle wheel turbine type flow meter based on the pelton wheel principle. This unique patented design makes the FTB600B Series a very accurate, repeatable, linear device.
1 FTB600B Series Installation C. Material Characteristics of PVDF (Polyvinylidene Fluoride) 1. Material of construction Trade name - Kynar All wetted parts of the FTB600B Series are PVDF, excluding the O-ring. Wetted parts include any part of the meter that will or could come in contact with the fluid. List of wetted parts: 1. Barbed fittings 5. End caps 2. Flow meter body 6. Strainer 3. Rotor 7. Bearings 4. Helical nozzle (Viton O-ring seal) 2.
FTB600B Series Operating Parameters 2 Section 2. - Operating Parameters A. Temperature Since the FTB600B Series has printed circuit boards molded into the body of the meter it is strongly recommended that 180°F not be exceeded. Exceeding 180°F can cause irreparable damage to the circuit boards. B. Flow Ranges The FTB600B Series is available in six different sizes, which cover a flow range from 0.1 to 120 lpm. Specific flow ranges FTB601B 0.1 to 2 lpm (0.03 to 0.53 gpm) FTB602B 0.3 to 9 lpm (0.08 to 2.

FTB600B Series Operating Parameters 2 C. Recommended Viscosity Range 1-5 cSt (w/o correction) The effects of changing viscosity on the FTB600B Series are the same as any other turbine flow meter. It is important to remember that a turbine meter is a viscosity dependent device, where as the viscosity increases the linearity of the flow meter will decrease. (Water like viscosities are ideally suited for use with the FTB600B Series) The FTB600B Series is factory calibrated with water.
3 FTB600B Series Silicone Treatment Section 3 - Silicone Treatment Silicone treatment is standard for all types of the FTB600B Series series electronics.
FTB600B Series Infrared Sensors 4 Section 4 - Infrared Sensor A. Supply Voltage 24 Vdc. Do not exceed 24 Vdc. Doing so can cause overheating and eventual failure of all PC boards. Printed circuit boards are nonrepairable. B. Frequency Output 1. Square wave pulse, unscaled (See Figure 4-1) 2. Output impedance 75 ohms 3. Directly proportional to flow rate 4. Output - dc frequency 5. Offset 0.64 volts 6. Peak voltage = Supply voltage - 1.2 volts 7. Peak to peak voltage Supply voltage - 1.2 volts - 0.

Frequency Ranges for (non-cartridge models) pulses/l Model Frequency (Hz) K-Factor FTB601B 60 to 1200 36,000 FTB602B 40 to 1200 8,000 FTB603B 27 to 800 3,200 FTB604B 20 to 600 1,200 FTB605B 18.75 to 562 450 FTB606B 15 to 450 225 D. Cable Requirements 1. 20 to 22 AWG (American Wire Gauge) 2. 4 conductor-shielded cable. NOTE Avoid influences of strong electromagnetic forces as they can damage components on the PC boards.

5 FTB600B Series Installation Section 5 - Installing the FTB600B Series in the fluid line. A. Make sure the fluid is compatible with PVDF (polyvinylidene fluoride) and meets viscosity, pressure and temperature parameters of the FTB600B Series. The fluid must also meet filtration requirements as listed in 3D. B. Install the FTB600B series in the fluid line with the arrow pointing in the direction of the flow. C.
