Hello, dear friend. In the basement of an apartment building, a heat meter and hot water supply was installed. Instead of old, broken meters, new ones were installed. The flow meters themselves were no longer on the pipes. But the calculator remained on the wall. The foreman said to take it off and throw it in the trash. But I disobeyed and secretly took it for myself. Black box with dial.
It looks like an old Soviet electricity meter, with a bunch of wires.
These wires were laid to ultrasonic flow meters and thermocouples (KTSPR-001).
He removed the upper part of the device, having previously torn off the verification seal. On the case there is a serial number and the name of the assembler. This is in case you need to find a "scapegoat" when the device breaks down.
I even connected it to the network. At the same time, the device turned on with a green LED. Surely the heat calculator was working, the verification period simply expired.
Having removed the inner metal casing, we find ourselves in the kingdom of microcircuits and radio components, coated with varnish.
This device was produced either in Sarapul or in Arzamas. According to the document found on the net. These radio factories worked for the defense industry. And in the 1990s, they had to produce more consumer goods to survive. This is probably why such a heat meter was born. Created by Soviet engineers using radio components containing precious metals, but at the same time, the LCD was used from a foreign company. This is what an open curtain means.
As for precious metals in this equipment, there are capacitors "KM" and others. When disassembling it, you can earn a small penny.
But my hand does not rise to break the miracle of post-Soviet thought into scrap metal and destroy it. Maybe there are radio amateurs among the readers who would use this device for any crafts. I'll send him free of charge.
Surely there will be many such fans. Therefore, I decided whose comment within a month would gain the most likes from other readers from the date of the article's release. I'll send it to that one. Don't pass by. Write a comment, subscribe to the channel and like. Perhaps this "miracle" will be yours.
By the way, there is a document on this device on the net. Link here.
