Machine monitoring systems: On-premise vs. Cloud based
On-premise (also called Enterprise) system
Everything is in your shop floor.
The machines are connected through LAN (which can be wired or WiFi) to a local server. Users can see reports if they are on the same LAN, from within the shop floor.
Cloud based system
Machines are connected through IOT to the Cloud, through the mobile phone network. Users can see reports from the internet, from anywhere in the world.
Here is the comparison. The ‘tracker’ here refers to the hardware device connected to a machine that tracks the activity of the machine.
On-premise, WiFi LAN
On-premise, Wired LAN

What is Proof and ABV on alco(hic!)hol bottles ?
Alcohol by Volume, or ABV, is the percentage of ethyl alcohol in the total volume. You’ll find ABV Alcohol by Volume also written as ABV, V/V, or alc/vol. All these mean the same thing – 40 ml of alcohol in every 100 ml of contents (the other 60 ml being mainly water): 40 % V/V, 40 % ABV, Alc. 40% by vol, 40 % vol, 40% alc/vol.
Proof is a more complicated and confusing term.
The term ‘Proof’ originated in England 500 years ago. Rum was taxed at different rates depending on its alcohol content. The rum was tested by soaking a pellet of gunpowder in it. If the gunpowder could still burn after the soaking, the rum was rated as ‘above proof’ and taxed at a higher rate. Gunpowder would not burn after soaking in rum that had less than 57.15% ABV. So rum that contained this percentage of alcohol was said to be “100° (one hundred degrees) proof”. To convert Proof to ABV, just multiply by 0.5715.
See the label below, and note the year of manufacture. It’s 86 % ABV (that’s a crazy amount – the average whisky is about 40 %), which means 86 % alcohol and 14 % water. The label actually says “flammable”.
In the US, proof merely meant 2 x ABV. So if a bottle said 100 % Proof, it meant 50 % ABV.
Very confusing, this Proof business. Happily for us tipplers of today, Proof is obsolete.
ABV, which is easy to understand even with faculties dulled by alcohol, is the standard used the world over.
Here’s a page that has ABV for various types of liquor.
