The following is a detailed analysis of customer needs and recommended optimization suggestions, combining product parameters and industry experience to ensure accurate selection and suitability for actual application scenarios:

 

I. Verification of Matching Degree between Customer Core Needs and Recommended Products

 

Requirement Parameters | Customer Original Requirements | Recommended Product Parameters | Matching Conclusion

 

Media Type | Superheated Steam | Hot Steam (clearly marked as applicable to superheated steam) | Fully matched; vortex flow meters are a common solution for steam measurement.

 

Temperature Range | 0-400℃ | Upper temperature limit 400℃ (covers requirements) | Fully matched; needs confirmation regarding whether the customer is involved in low-temperature condensation risks (e.g., during start-up and shutdown).

 

Pressure Range | 40 bar (≈4.0 MPa) | Pressure rating 4.0 MPa | Fully matched; needs confirmation regarding whether it is a steady-state pressure or has pulsating pressure.

 

Flow Rate Range | 0-35 tons/hour | Nominal 35 tons/hour (actual lower limit approximately 5% of the range) It needs to be explained to the customer that the vortex flow meter cannot measure zero flow, but it can cover 5%-100% of the range (i.e., 1.75-35 tons/hour). It needs to be confirmed whether the customer accepts this range.

II. Technical Advantages and Industry Application Value of Recommended Products

 

Integrated Temperature and Pressure Compensation Function

Core Value: The density of superheated steam changes significantly with temperature and pressure. The integrated temperature and pressure sensor can compensate for fluctuations in operating conditions in real time, ensuring flow measurement accuracy (traditional vortex flow meters require external compensation devices, increasing costs and potential failure points).

 

Data Support: 1.5% accuracy is based on the comprehensive error after temperature and pressure compensation, 2-3 times better than uncompensated solutions.

 

Isolated Replacement Design

Maintenance Convenience: The sensor and measuring tube can be separated, allowing probe replacement without cutting the pipeline, suitable for high-temperature steam pipelines (high downtime maintenance costs).

 

Application Scenarios: Continuous production industries such as chemical and power industries, reducing annual maintenance time by more than 50%.

 

Vibration and Interference Resistance

Technical Configuration: Employs dual-probe differential detection + digital filtering algorithm to effectively suppress the impact of pipeline vibration (such as steam hammer, pump outlet vibration) on the signal.

 

Industry Certification: Complies with ISO 13359 vortex flow meter vibration resistance standard, suitable for operating conditions with vibration levels ≤5mm/s.

 

III. Key Details Requiring Further Confirmation with the Customer

 

Flow Rate Limit and Process Requirements

 

Issue: The vortex flow meter cannot measure zero flow (no signal when there is no vortex). The customer's stated flow rate of "0-35 tons/hour" may include low flow monitoring requirements during start-up and shutdown.

 

Suggested Solution: If extremely low flow monitoring is required (e.g., <5 tons/hour), an orifice plate flow meter + differential pressure transmitter (range ratio up to 10:1) can be added.

 

If only process control is required, the recommended product flow range (1.75-35 tons/hour) is sufficient.

 

Explosion-proof and Safety Certification

 

Risk Point: If the steam pipeline is located in an explosive environment (e.g., chemical plant, oil and gas platform), it is necessary to confirm whether an explosion-proof type (e.g., ExdIICT6) is required.

 

Recommended Product Status: The currently recommended model does not specify an explosion-proof rating; supplementary certification is required based on the customer's site environment.

 

Installation Direction and Straight Pipe Section Requirements

Standard Requirements: Vortex flow meters require a 10D upstream and 5D downstream straight pipe section (D is the pipe diameter). If site space is limited, a rectifier or a reduced-diameter flow meter can be recommended.

 

Customer Confirmation Items: Provide a pipe layout diagram or site photos to assess whether the straight pipe section meets the requirements.
