High-Cost Performance Selection Guide (Three-Step Approach)

Step 1: Ensure “Good Enough Performance” — Avoid Overpaying for Unused Features

• Accuracy: Most Chinese ultrasonic level transmitters provide 0.2%–0.5% accuracy, which is sufficient for water, wastewater, and storage tank applications. Ultra-high precision (0.1%) from imported devices is often unnecessary.

• Practical functions: Identify your core needs — if you only need on-site display and 4–20mA output, a basic model works. For networking (RS485/Modbus) or alarm output (relay), choose advanced models with these features.

• Working conditions: For tanks with light foam or steam, select models with false echo learning or echo curve display — Chinese brands now handle these conditions effectively at a fraction of the cost.

Step 2: Focus on Key Details for Stability and Durability

• Probe material: Choose based on liquid type:

  • PP: For mild acids/alkalis.

  • PVDF or PTFE: For strong acids, corrosive or hygienic environments.
    These materials outperform stainless steel in chemical resistance while keeping costs reasonable.

• Protection level: For outdoor or humid sites, ensure IP67 or higher. This is the baseline for long-term reliability.

• Process connection: Double-check thread/flange size for compatibility. A mismatch may lead to extra adapters and leakage risks.

Step 3: Choose Reliable Suppliers

• Technical support: Prefer brands that offer clear selection guidance and responsive technical service.

• Warranty & after-sales: Check the warranty period (1–2 years) and after-sales policy. Localized service reduces downtime and maintenance costs.

• Sample testing: For critical projects, always test a sample before bulk orders. Field testing is the most direct proof of performance under your actual conditions.

Conclusion

Chinese ultrasonic level transmitters have reached a mature and reliable stage in both performance and technology. By focusing on your actual application needs, key technical parameters, and supplier reliability, you can find a product that is stable, affordable, and perfectly suited for your working conditions.
Before making a large purchase, communicate clearly with the manufacturer and conduct on-site testing — this ensures you choose a solution that truly works for you.
