However, with the increasingly harsh application environment and the continuous improvement of safety requirements, the performance and stability of mass flowmeters have been challenged to a higher level. Especially in harsh environments such as explosive, corrosive, high temperature and high pressure, the transmitter housing of the mass flowmeter is an important component to protect the internal electronic components and sensors, and its performance is directly related to the overall reliability and safety of the flowmeter.

[0003] Traditional transmitter housing designs usually adopt a single-chamber structure, which meets the basic protection and installation requirements to a certain extent. However, with the deterioration of the industrial environment and the improvement of safety standards, the single-chamber design has gradually exposed its shortcomings in terms of explosion-proof performance, structural strength, electromagnetic compatibility, and thermal management.

[0072] Traditional mass flow meter transmitter housings have the following disadvantages:

[0073] 1. Insufficient explosion-proof performance: Because traditional designs do not fully consider the requirements of explosive environments on the shell, there are safety hazards when used in explosive environments. This may be due to unreasonable explosion-proof structure, improper material selection or poor sealing performance.

[0074] 2. Insufficient structural strength: The existing shell may be deformed or damaged when subjected to external pressure, impact or vibration, affecting the normal operation of the flow meter. This is usually related to uneven wall thickness design, unreasonable structural layout or insufficient material strength.

[0075] 3. Low protection level: Existing technologies may not be able to effectively prevent external dust, moisture or other contaminants from invading the interior of the housing and damaging internal components. This may be due to imperfect sealing measures, unreasonable interface design or lack of necessary protective structures.

[0076] 4. Poor electromagnetic compatibility: In an environment with severe electromagnetic interference, the existing housing may not provide adequate protection for the internal electronic components, resulting in signal distortion, equipment failure or performance degradation. This is usually related to insufficient electromagnetic shielding measures, poor grounding design or unreasonable line layout.

[0077] 5. Poor thermal management performance: In high temperature environments, existing technologies may not be able to effectively dissipate heat, resulting in overheating of internal components, performance degradation, or shortened life. This may be due to unreasonable heat dissipation structure design, improper heat dissipation material selection, or lack of necessary thermal management strategies.

[0078] In view of the above-mentioned shortcomings, the object of the present invention is to provide a mass flow meter transmitter housing, which can:

[0079] 1. Enhance explosion-proof performance to ensure safe use in explosive environments.

[0080] 2. Improve structural strength and resist external pressure, impact and vibration.

[0082] 4. Improve electromagnetic compatibility and protect internal electronic components from electromagnetic interference.

[0083] 5. Optimize thermal management performance to ensure stable operation in high temperature environment.

[0084] By achieving the above objectives, the present invention can achieve the following technical effects:

[0085] 1. Provide a higher level of explosion-proof protection and reduce the risk of use in explosive environments.

[0086] 2. Enhance the structural stability and durability of the shell and extend its service life.

[0087] 3. Effectively isolate external pollutants and protect the cleanliness and integrity of internal components.

[0088] 4. Reduce the impact of electromagnetic interference on flow meter performance and improve measurement accuracy.

[0089] 5. Optimize heat dissipation performance to prevent internal components from overheating and ensure reliable operation of the flow meter in high temperature environments.

[0090] The key points of the mass flow meter transmitter housing protection provided by the present invention are as follows:
