FAQ

Q: What is the difference between a flange-mounted differential pressure transmitter and a conventional DP transmitter?

A: A flange-mounted model connects directly to the process vessel or pipeline through a flange assembly, making it suitable for level measurement and applications involving viscous, corrosive, or contaminated media.

Q: How are the transmitters packaged for international shipment?

A: Products are typically packed with protective cushioning in export cartons or wooden cases, depending on order quantity and transportation requirements.

Q: What information is required for model selection?

A: Buyers typically provide the measurement medium, pressure range, operating temperature, flange specification, output signal, installation method, and certification requirements.

Q: What is the recommended recalibration interval?

A: For most industrial applications, recalibration is recommended every 12 to 24 months. The actual interval depends on process conditions, regulatory requirements, and criticality of the measurement point.

Q: Are spare parts available for long-term maintenance?

A: Yes. Common spare parts such as display modules, electronic boards, seals, gaskets, and process connection components can be supplied to support maintenance and inventory planning.

Q: Can the transmitter be used for both level and flow measurement?

A: Yes. It can measure differential pressure for flow applications and liquid level when installed on tanks, vessels, or pressure containers.
