Product Q&A

Q:What media and tank applications is this double flange differential pressure level transmitter suitable for?

It is ideal for closed, pressurized storage tanks, vacuum vessels, and open tanks containing liquids, semi-liquids, or paste media compatible with 316 stainless steel. Its dual remote seal diaphragms prevent clogging, buildup, and corrosion while accurately measuring level without impact from bubbling or sediment deposition.

Q:Do you offer OEM, ODM, or custom flange connection options?

Yes, we provide full OEM and ODM customization services. We can customize the flange standard (ANSI, DIN, JIS), capillary lengths (e.g., 3m, 5m, 10m), measuring range (up to 0-150m), capillary fill fluids, and mounting configurations to meet your specific project requirements.

Q:What output signals and display options are available for this level gauge?

The transmitter provides a standard 2-wire 4-20mA DC signal output with strong anti-interference and long transmission distance capability. It features field-readable display options, including 0-100% isometric scale, LCD, or LED indicator heads.
