Product Q&A

Q:Does this flowmeter require an external power supply?

No, the mechanical pointer version operates without power. However, the intelligent version with LCD and HART support requires 24VDC, 220VAC, or battery power.

Q:What materials are available for the measuring part?

Available materials include stainless steel, Hastelloy, Titanium, PTFE, and FEP lining to meet specific pressure and corrosion requirements.

Q:What is the accuracy level of the flowmeter?

Standard accuracy is 2.5%, with special types offering 1.5% or 1.0%. Temperature drift is less than +/- 0.1% per 10 degrees Celsius.

Q:Can the flowmeter be customized for specific flange standards?

Yes, we offer customization for flange standards, thread types, and other connection modes according to customer requirements.

Q:What is the maximum turndown ratio?

The standard turndown ratio is 10:1, while special types can achieve a ratio of up to 20:1.
