Product Details

FLR1000 Series flow sensors can measure extremely low flow rates from 20 mL/min to 500 L/min. These sensors are suitable for a wide variety of industrial, commercial, and laboratory flow applications. Not for use with Hydrogen or Helium. FLR1000 Series flow sensors operate on 12 Vdc power and are designed for incorporation into data acquisition systems that supply 12.5 Vdc to sensors and receive 0 to 5 Vdc linear signals in return. Because of their cost effectiveness, FLR1000 Series units may replace conventional glass tube and ball flow meters in applications in which an electrical signal proportional to flow rate is desired.

The FLR1000 Series uses a Pelton-type turbine wheel to determine the flow rate of the gas. The rotation rate of the turbine wheel is linear over a wide dynamic range. The electro-optical system consists of a diode emitting energy in the infrared spectrum. Light energy is alternatively reflected and absorbed from "spokes" deposited on the small turbine wheel. This reflected light energy is detected by a photodiode. Thus, as the turbine wheel rotates in response to gas flow rate, electrical pulses are generated. Processing circuitry provides a DC voltage output proportional to the flow rate. For example, output signal is 1.0 Vdc at 20% of rated flow, 2.5 Vdc at 50% of rated flow, 4.0 Vdc at 80% of rated flow, and 5.0 Vdc at 100% of rated flow. Sensors can handle 20% above their rated flow without being damaged.

Rated 4 out of 5 by from These work as expected We have used these in the past, so we know what to expect.

Rated 4 out of 5 by from C+ to B- FLR1204 20-100L/min works. Spec sheet states "fast response" I did not find this to be true. Power requirements states 30mA (typical) with 11.5 V to 15.0 V supply, so 0.345 W to 0.45 W. Data logger has .4 W. Will data logger power the senor or not??? Also, the FLR1204 sensor is on a by-pass plumbing, I was not aware of this.

Rated 3 out of 5 by from works and functions but limited Purchased unit but had to return the first one due to a defect on the screen. got the second one in and it works great, in an environment without any back pressure. The second any pressure is added to the mix the gauge is rendered useless. unfortunately the testing we are performing requires some pressure while still maintaining flow and we are not able to get the value we are looking for. looking at other gauges that might have a different system to make our test work.

Rated 3 out of 5 by from Warning - Will not work with Hydrogen Will not work with Hydrogen even though the manual says call Omega for Hydrogen calibration info. Talked to an Omega engineer and was told they cant give calibration info because the unit will leak hydrogen.

Can I use this meter as is to measure a water flow but also a more viscous (10 cP), transparent mix (water with honey) or do I need to do a measurement and calculate a conversion ("k") factor for the viscous fluid?

Asked by: cristel
Thank you for your inquiry about this flow meter. Unfortunately, 10 cP is the maximum viscosity that the flow meter can handle or is recommended to measure. An alternative for viscous liquids is using a positive displacement flow meter.

What is the pinout for this sensor in a 4-20 mA model? P/N FLR1009ST-I. Thank you.

Asked by: Stingray36
Thank you for your inquiry about the flow meter. The manual outlines the wire schematic flow the "-I' flow meter such as the FLR1009ST-I meter you have. It goes as follows on page 13 of 34. The RED wire should be connected to the Positive of the power source. The BLACK wire should be connected to the Negative ( Ground ) of the power source. The WHITE wire provides the signal output (active current) and should be connected to the positive terminal of the display, data acquisition system or current meter with an impedance of 0 - 500Ω (Ohms). The GREEN wire is NOT used.

Can I use this to measure the permeability of prepreg composite under a vacuum bag?

Asked by: Robyn123
Thank you for your inquiry about the flow meter. Unfortunately, it is not recommend to use under vacuum. The FMA1700/1800A mass flow meters for gases can measure flow rate in vacuum conditions.

What is the Mfr and P/N of the electrical connector? Or, better yet, the mating connector/crimps?

Asked by: Pablo
Thank you for your question? We do not sell the connector alone. If you are looking for the power supply connector, the part number for the connector and cable is FLR1000-PW for 120VAC, or FLR1000-230PW for 230VAC. If you are looking for the communication cable connector, the part number for the connector and cable is FLR1000-C.

The user's guide / manual for these units (FLR1003 / FLR1203) indicate Viton O-rings as standard, but EPDM optional. Can I order the EPDM option?

Asked by: SeanS
Yes. Add suffix "-EPDM" to the part number for the EPDM O ring option.
