Supported Applications
The Omega FTB600 Series consists of all-plastic, axial paddle wheel turbine flow meters designed for ultra-low flow applications. Based on the Pelton wheel principle, these sensors are suitable for use in medical, pharmaceutical, chemical processing, pulp & paper, semi-conductor, and agricultural industries.
The series is engineered to measure clear, transparent, or translucent fluids that transmit infrared light. The design inherently bleeds off entrained gas to improve accuracy and eliminates the need for flow straighteners or special inlet piping.
Operating Conditions & Performance
The FTB600 Series offers six distinct measurement ranges spanning from 0.1 to 120 LPM, with a turn down ratio up to 30:1. The sensor provides an accuracy of ±1% of reading and repeatability of ±0.1% of reading.
Performance is maintained within the following operating parameters:
- Ambient Temperature: -40 to 85°C (-40 to 185°F)
- Working Pressure: 150 psig at 79°C (175°F)
- Viscosity Range: 1 to 15 cSt
- Maximum Pressure Drop @ Maximum Flow: 30 psi on all units; 6.5 psi on FTB601
The sensor utilizes an infrared electro-optical transmitter and receiver with a wavelength of approximately 85 nm for non-contact rotor detection. The fluid must transmit this infrared light; the series is not suitable for use with red liquids.
Configuration Options
The FTB600 Series supports multiple configurations to accommodate specific installation needs, including hose barb or threaded connections and various flow ranges defined by model number. The wetted parts are constructed from PVDF (polyvinylidene fluoride) with FKM O-rings.
Model Ranges and Dimensions
The series includes six primary models covering the following flow envelopes:
- FTB601B: 0.1 to 2 LPM (K Factor: 36,000 pulses/Liter)
- FTB602B: 0.3 to 9 LPM (K Factor: 8,000 pulses/Liter)
- FTB603B: 0.5 to 15 LPM (K Factor: 3,200 pulses/Liter)
- FTB604B: 1 to 30 LPM (K Factor: 1,200 pulses/Liter)
- FTB605B: 2.5 to 75 LPM (K Factor: 450 pulses/Liter)
- FTB606B: 4 to 120 LPM (K Factor: 225 pulses/Liter)
Connections and Options
Models are available with standard hose barb connections. For NPT threaded connections, add the suffix "-T" to the model number at no additional charge.
- NPT Sizes: ¼ (FTB601), ½ (FTB602/3), ¾ (FTB604), and 1¼ (FTB605/6)
- Included Accessories: A strainer is included in models FTB602B through FTB606B.
Electrical Specifications
The sensor outputs a square wave pulse signal. It requires an 8 to 24 Vdc power supply with current consumption between 6 and 33 mA. A 0.9 m (3') cable is included.
Key Product Differences
Variants within the FTB600 Series are distinguished by their flow range, physical dimensions, K factor, and connection type. The "-T" suffix denotes units configured with NPT threaded connections rather than hose barbs; these threaded versions feature different overall lengths compared to the standard models.
Models FTB602B through FTB606B include an integrated strainer, whereas the FTB601B does not. The series is offered in six base model numbers (FTB601B–FTB606B), each corresponding to a specific flow range and K factor value as listed above.

Omega FTB600B Faulty Labelling Added Cost
I installed this unit according to the proper direction of flow indicated on the label. Along with the integration of the Omega DPF701 display, I spent many hours trying to get the assembly to indicate the proper flow rate. I finally realized that the direction-of-flow label may be affixed incorrectly. I checked the picture in the manual and, sure enough, the label was upside-down. I reversed the flow and the assembly functioned properly. For $600, I expect a better quality product that does not cost me valuable time to implement. Photo attached.

Compact, easy to install and set up
This sensor is relatively small. After calling tech support for some assistance, it was easy to correctly connect it with the meter. The meter was simple and quick to configure, too.

Good flowmeter for lower temperatures
The flowmeters are easy to setup and use. You need a pulse counter card, alternative is a pulse to voltage converter, for example IFMA0035.

Don't operate at the upper temperature limit.
I have burnt out 2 of these flowmeters in a non-corrosive, hot water application. These flow meters are accurate out of the box and have good turndown ratio but I am operating them just under their spec at 180F. The manufacturer claims 185F as the upper limit. I would expect a little wiggle room but I have gone through 2 devices already.

Does this meter send live results to a data source to be reviewed by the user?
Thank you for your inquiry about the flow meter. Yes, it will send an output when the application reaches the minimum threshold of flow rate as listed in the data sheet for each specific part number mentioned.

Which data logger can I use with this sensor to record the data?
Thank you for your question. The OM-CP-PULSE101A should work for your application. You will also need the IFC200 USB cable. link below.

A search for the DPF70 you recommend on another QA comes with 0 results. So, is there a display available to make this an actual meter? As it is I consider it to be just a flow sensor. I only need flow rate and I need a display that will work on 12 VDC
Thank you for your inquiry. The DPF70 is only a general series meter or display. If you are searching for a display to be powered up by 12 VDC, then, the DPF20-LV is a meter that will accept a pulse input and display flow rate.

FTP600 Series - Flow meter Program's User Guide - How to control/monitor the sensor remotely (over RS232 for example). I'm looking for command syntax. For example @U?Pxxxxxx<CR> is the command syntax to send setup data to the older model (DPF700) sensor.
Thank you for your inquiry about the FTB600 series turbine flow meter. Unfortunately, there is no commands to send to this flow meter since it only outputs a frequency. You may contact our Data Acquisition Group at das@omega.com and a colleague can advise on our LAYER N Technology available.

Is there an LCD display available for indication?
Thank you for your inquiry. We have the DPF70 series meter that will either, display, flow rate, total, or both. The DPF70 series is compatible to accept the input signal from this flow meter.
