SylvanLakeWH 24,172 #77 Posted September 24, 2019 (edited) Some kind of directional river flow gauge...? Kind of looks like the device in this picture... Edited September 25, 2019 by SylvanLakeWH 1 Share this post Link to post Share on other sites
CasualObserver 3,406 #78 Posted September 24, 2019 Appears all stainless... going to guess some sort of food/dairy/beer or chemical tank mixer? 1 Share this post Link to post Share on other sites

formariz 11,861 #80 Posted September 30, 2019 @Ed KennellIts a water current meter. What kind of need did you have for it Ed? Share this post Link to post Share on other sites

It is a really fine instrument that I didn't have the heart to scrap when we went to closed loop test stands with venturi type flow meters. The impeller has one of the most friction free bearings I have ever seen. With the flick of a finger, the impeller will spin forever. The venturi meters were eventually replaced with magnetic flowmeters. This flow meter was also used to measure flow during hydro turbine index testing by dropping the meter in front of turbine intake as shown in Jim's photo. The tail fins aligned the meter with the flow direction and the voltage produced by spinning impelled was calibrated for velocity. Other devices used to measure flow were pitot tubes and the salt velocity method. 4 Share this post Link to post Share on other sites
Ed Kennell 35,822 #83 Posted October 8, 2019 This should be easy as the modern day version are pretty common. But this is an earlier version that I have never seen before. Share this post Link to post Share on other sites

With the flick of a finger, the impeller will spin forever. https://en.wikipedia.org/wiki/Air_bearing Air bearings (also known as aerostatic or aerodynamic bearings) are bearings that use a thin film of pressurized gas to provide a low friction load-bearing interface between surfaces. The two surfaces do not touch, thus avoiding the traditional bearing-related problems of friction, wear, particulates, and lubricant handling, and offer distinct advantages in precision positioning, such as lacking backlash and static friction, as well as in high-speed applications.[1] A differentiation is made between aerodynamic bearings, which establish the air cushion through the relative motion between static and moving parts, and aerostatic bearings, in which the pressure is being externally inserted. Gas bearings are being mainly used in precision machinery tools (measuring and processing machines) and high-speed machines (spindle, small-scale turbomachinery, precision gyroscopes). 1 Share this post Link to post Share on other sites

Ed Kennell 35,822 #87 Posted October 9, 2019 It is an early version of a Pyrex pot handle with a glass handle circa 1940-45. This is the modern version. 2 Share this post Link to post Share on other sites

Obviously this would have to be an aerodynamic bearing as there is no external pressure source. This instrument is used in dirty unfiltered water so it must have some type of seal that is also near zero friction. More research needed. Share this post Link to post Share on other sites
