Is it possible to treat precision instruments in this way without treating the village chief as a cadre?

Random design, lazy on-site, laissez-faire supervision ;P

If you look carefully, it seems that there are many problems, such as the position of the bracket, water accumulation in the insulation site, etc.

The design and construction personnel are too inexperienced.

Inexperience is one of the reasons. The key point is that the technical person in charge or the professional person in charge has neglected his duty.

Can any hero explain it in detail? I don't understand?

What should you pay attention to when installing a mass flow meter? 1. The installation location should be chosen to avoid electromagnetic interference. The installation location of sensors and transmitters and cable laying should be as far away as possible from equipment that easily generates strong electromagnetic fields, such as high-power motors, transformer facilities, frequency conversion equipment, etc. 　　2. The mass flow sensor should be installed so that the sensor flow direction mark is consistent with the fluid flow direction. And make the arrow point in the same direction as the flow rate configured inside the transmitter. (Note: Mass flow meters can be used in both directions. If the installation direction is opposite to the actual flow direction, just modify the flow direction configuration in the transmitter. ) 3. The mass flow meter is a flow meter that measures based on the vibration principle of the measuring tube. Therefore, when installing the sensor, consideration should be given to providing solid support near the flanges of the process pipelines on both sides (about 2 to 10 times the pipe diameter) to avoid vibrations in the instrument and related pipelines. If strong pipeline vibration is unavoidable, it is recommended to use flexible pipes to isolate the pipeline system from the instrument sensors. 　　4. Since the mass flowmeter works based on the Coriolis force principle, in order to avoid the influence of gravity on the measurement accuracy. Whether the measuring tube of the mass flow meter is installed upward or downward, try to keep the measuring tube vertical or horizontal to the ground plane. 　　5. During installation, the connecting flange surfaces should be parallel to each other, and the centers of the two flanges should be on the same axis to avoid additional stress. It is strictly forbidden to use the sensor to straighten the upstream and downstream process pipelines, otherwise the measurement will be affected or even the sensor will be damaged. 　　6. On the upstream and downstream pipelines of the sensor, it is recommended to install stop valves and bypasses to facilitate zero adjustment, daily maintenance and to ensure that the sensor can be in a full pipe state when not working. Use a regulating valve downstream of the flow meter for flow control.

The pipeline support of this pipeline is also problematic.
