Is it okay to arrange the flow meter and control valve in this way?

I’m not an expert; it’s just my personal opinion. The layout of the flow meters and valves is generally fine; it’s more accurate for liquid media, while there are deviations for gases. If the straight section of pipe downstream of the equipment is long enough, it’s better to arrange the components in that straight section. Maintaining the flow meter is a bit troublesome as there are no inlet and outlet stop valves.
Air tends to accumulate at high points, which is detrimental to flow meters.
The actuator of the control valve is quite heavy; isn’t it better to arrange it horizontally? When arranged vertically, it is recommended to provide separate support for the actuator. The level gauge must meet the requirements for straight pipe sections, and its positioning must prevent situations where incomplete flow occurs due to air accumulation at higher points. Is this a pipeline that was added as a temporary variable update? Why isn’t a suitable location planned for valuable items like control valves and flow meters so that they can be placed there? :lol
The control valve should be installed horizontally as much as possible, and the straight pipe sections before and after the flow meter must meet the required specifications. It’s fine to use it this way, but it’s not very convenient during inspections and maintenance
The control valve should be installed horizontally as much as possible, and the straight pipe sections before and after the flow meter must meet the required specifications.
In accordance with design specifications, control valves are generally installed horizontally, with manual valves placed at both the front and back to facilitate tasks such as removing the valve from service. Flow meters used for measuring liquid flow are also usually installed horizontally, and the required lengths of straight pipe sections in front of and behind these flow meters vary; it is necessary to ensure that the appropriate lengths of straight pipe sections are provided based on actual conditions.
Flow meters have installation requirements; according to the manufacturer’s specifications, there must be a certain length of straight pipe ahead of and behind the flow meter
