Product Q&A

Q:What is the MOQ for this product?

The MOQ is 1 piece. Sample orders are also accepted.

Q:Is this meter suitable for high-temperature caustic soda applications?

Yes! It is specifically designed for high-temperature caustic soda recovery, withstanding up to 180 degree C for hot alkali processes.

Q:Why are PTFE/PFA lining and Hastelloy electrodes important for caustic soda?

Caustic soda (NaOH) is highly corrosive, especially at elevated temperatures. PTFE/PFA lining provides excellent chemical resistance, while Hastelloy electrodes offer superior corrosion protection against aggressive alkali solutions.

Q:What is the maximum pipe size this meter can measure?

This insertion type meter can measure pipe sizes from DN350 up to DN2000. Larger sizes are available upon request.

Q:What output signals are available?

RS485 Modbus (standard), with 4-20mA, pulse output, and HART protocol available as options.
