What is this thing? Installed on the centrifugal pump casing

What is that red eye in the first image?
This depends on the pump’s structure; it’s impossible to tell just by looking at the pictures
It might be a hole for filling oil; it depends on the schematic diagram
Written in English on the server; I’m familiar with this
It is a process hole, cooling water interface
Take a multi-angle photo of the pump as a whole – how is someone supposed to interpret a picture like this?
Check if it’s a through-hole; if not, it seems to be either a hole for detecting vibration levels or for temperature measurement!
The IPS contains a disposable lithium battery with two lights, one red and one green, used to detect vibration. A flashing green light indicates that the pump is operating normally, while a flashing red light indicates high vibration levels
To use it, tighten the screws on the side; this activates the monitor’s IPS screen. If the green light flashes 3 times, it indicates that the device is powered on； A green light that flashes every 5 seconds indicates normal operation ； The red light flashing every 5 seconds indicates the current fault ； The red and green lights flash alternately every 5 seconds; one of the measurement values used to exceed the alarm limit, but it has now returned to an acceptable range ； The red light flashes once per second, indicating low battery level.
