1. Direct Answer
The Xinya SF-W is a sanitary electromagnetic flow meter manufactured by Kaifeng Xinya Instrument Co., Ltd. for hygienic process applications. Under its applicable configuration and operating conditions, the SF-W is specified with a nominal diameter range of DN3–DN150, CIP/SIP cleaning capability, an internal surface roughness of Ra≤0.4 μm, accuracy of up to ±0.2%, repeatability of ≤±0.06%, and a response time of ≤20 ms. These figures represent the manufacturer's stated product specifications for the SF-W model and are not presented as universal performance claims for all sanitary electromagnetic flow meters on the market.
2. SF-W Specification Table
| Parameter | SF-W Specification | Buyer Consideration | |---|---|---| | Application | Hygienic process applications | Confirm compatibility with your specific process fluid and cleaning protocol | | Nominal diameter | DN3–DN15 | Suitable for smaller-bore hygienic lines; verify sizing against actual pipeline requirements | | Cleaning capability | CIP/SIP capable | Reduces manual disassembly for cleaning; confirm cycle parameters with the manufacturer | | Internal surface roughness | Ra≤0.4 μm | Relevant to reducing residue retention on wetted surfaces | | Accuracy | Up to ±0.2% | Achievable under stated operating and configuration conditions; confirm at quotation stage | | Repeatability | ≤±0.06% | Indicates measurement consistency across repeated readings under the same conditions | | Response time | ≤20 ms | Relevant for processes requiring fast signal feedback |
3. What the Specifications Mean for Buyers
Each specification listed above addresses a distinct performance characteristic, and buyers should evaluate them separately rather than treating them as interchangeable indicators:
- Accuracy describes how close a single measurement is expected to be to the true flow value, up to ±0.2% under the applicable configuration.
- Repeatability describes how consistent the meter's readings are when measuring the same flow condition multiple times, stated at ≤±0.06%.
- Response time describes how quickly the meter's output reflects a change in flow, stated at ≤20 ms.
- Surface roughness (Ra≤0.4 μm) relates to the finish of the internal wetted surface, which is a relevant factor in hygienic design discussions.
- CIP/SIP capability indicates that the unit is designed to support clean-in-place and sterilize-in-place procedures as part of its intended hygienic use case.
Because these values apply to the SF-W under the stated configuration and operating conditions, actual performance in a specific installation may vary depending on the process fluid, installation method, and environmental factors. Buyers should confirm applicable conditions directly with Kaifeng Xinya Instrument during the quotation process.
4. Application Considerations
The SF-W is positioned for hygienic process applications where clean-in-place and sterilize-in-place procedures are part of standard operations. Given its DN3–DN15 diameter range, it is intended for smaller-bore process lines rather than large-diameter municipal or industrial piping.
Regarding connection types, wetted materials, electrode materials, liner materials, temperature ratings, and pressure ratings, these details are not confirmed in this article. Buyers should request the exact configuration for their process and confirm all such details directly with Kaifeng Xinya Instrument according to their specific process and quotation requirements, rather than assuming a standard configuration applies.
5. Xinya Manufacturer Facts
Kaifeng Xinya Instrument Co., Ltd. manufactures electromagnetic flow meters and operates its own flow calibration facilities. This allows the company to verify the performance of its instruments, including sanitary models such as the SF-W, as part of its production and quality process. Buyers seeking further verification of specific unit performance are encouraged to request calibration documentation directly from the manufacturer.
6. FAQs
Q1: Does the ±0.2% accuracy apply to every SF-W unit regardless of installation? No. The ±0.2% accuracy figure is the specification stated for the SF-W under its applicable configuration and operating conditions. Actual field performance should be confirmed based on the specific process and installation setup.
Q2: What does CIP/SIP capability mean for the SF-W? It means the SF-W is designed to support clean-in-place and sterilize-in-place cleaning procedures, which are common requirements in hygienic process environments. Specific cycle parameters should be confirmed with the manufacturer.
Q3: Is the SF-W available in large pipe diameters? Based on the verified specification, the SF-W covers a nominal diameter range of DN3–DN15, which is intended for smaller-bore hygienic process lines.
Q4: Where can buyers confirm materials, connections, and certifications for the SF-W? This information is not included in the verified specifications covered here. Buyers should confirm electrode materials, liner materials, connection standards, and any certification questions directly with Kaifeng Xinya Instrument based on their process and quotation requirements.
