Review: Nice product but the nuts to mount it were missing. - I bought this rotameter to measure and control fairly low flows of carbon dioxide gas. The graduations on the scale are for oxygen flow but I can apply a factor or even recalibrate it for carbon dioxide. I like the metal barbed nozzles which easily take 1/4" thick-walled silicone tubing. The needle valve is finely made with a smooth sharp metal cone adjusted into a metal seat. It's important that these rotameters are mounted absolutely vertically for best accuracy. I designed a 3D-printed stand to hold the rotameter. However, the nuts that are needed to mount it (and are shown in the desertcart listing) were not included with the product. These are very unusual nuts with special threads and aren't locally available. So, now I have to take the time, trouble and expense to find suitable nuts online before I can mount this device. Either that or design and 3D-print some nylon nuts. I am not at all pleased about this - why can't the vendor include these difficult-to-find nuts with the product as expected in the desertcart listing? UPDATE I managed to identify the required nuts as being M10 x 1.0. It would cost me ~$10 to order a packet of these on desertcart (they're not available locally). I just printed some flanged nuts on my 3D printer out of PETG - these worked well - see photos. ## Features - Mainly used to detect oxygen flow, control the flow of oxygen, the gas flow can be detected - Product function: to measure oxygen and other gas single-phase non-pulsating flow - Flow range: 0.1-1.5 LPM - Tips:When using the flowmeter, the output pressure of the gas cylinder should be adjusted to around 0.1-0.2Mpa. If the float keeps floating to the top, it means that the actual flow rate has exceeded the range of the flowmeter - Usage: Often used for home brewing, malt juice oxidation, and beer brewing; It can also be used for aquaculture, releasing oxygen into aquariums, and any other place where oxygen flow needs to be monitored ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01N0UWZ2T | | Best Sellers Rank | #47,402 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #30 in Flowmeters | | Date First Available | December 27, 2016 | | Is Discontinued By Manufacturer | No | | Item Weight | 3.52 ounces | | Manufacturer | JIAWANSHUN | | Package Dimensions | 5.2 x 3.15 x 1.85 inches | ## Images ![JIAWANSHUN Oxygen Air Flow Meter 0.1-1.5LPM Gas Flow Regulator Gas Flowmeter with Copper Connector - Image 1](https://m.media-amazon.com/images/I/61byjfETsZL.jpg) ## Questions & Answers **Q: What is the ball made of?** A: It is made of glass. How do I know? I just accidently crushed mine when I put it back together after putting plumbers tape on both connectors and the regulator because it leaked air. **Q: Do i use the middle, bottom, or top of the ball for measuring reference ? also, important: can you answer this with 100% certainty of your claim?** A: Bottom of the ball. I am willing to stake your life on it (not mine though, the thing costs $17, how certain can you be for $17?). **Q: Can this be used to measure carbon dioxide flow? is there a conversion factor for converting the flow rate to co2?** A: Yes, of course you can! You'll need to apply a factor to the scale reading or recalibrate it yourself with carbon dioxide. There's a chart of the factors for a large variety of gases relative to air on the Mattheson website - search on-line for "Rotameter Conversion Factors". Because this rotameter is calibrated for oxygen and not air, you'll need to ratio the relative factors for the two gases. Oxygen is 0.951 and carbon dioxide is 0.808. Anyone who says you can't do this doesn't know what they're talking about :) **Q: Hi, We are planning to purchase the product for our lab. Due to it will belong to the, is there an email to get a quote for it?** A: With Amazon you can always get a printable receipt for your purchases.
