What Flow Calibration Systems Does Xinya Instrument Manufacture?
Kaifeng Xinya Instrument Co., Ltd. manufactures both flow measurement instruments and flow calibration systems. This article focuses specifically on the flow calibration systems Xinya produces, their typical application scope, and what buyers should know before requesting a customized configuration.
Verified Manufacturer Facts (Xinya-Specific)
The following information reflects Xinya’s stated manufacturing scope for flow calibration systems:
- Xinya manufactures liquid flow calibration systems and gas flow calibration systems.
- Xinya also manufactures flow meters (electromagnetic, turbine, vortex, Coriolis, gas turbine, Roots, and related types) as a separate but related product line.
- Xinya operates its own calibration facilities, which are used for internal factory measurement and verification of meters it produces.
- Calibration system uncertainty figures below are described as applicable "under system conditions and configuration," meaning actual performance depends on the specific setup delivered.
No claims regarding annual production capacity, project case studies, delivery timelines, pricing, or third-party system certifications are made in this article, as these are not part of the verified information available.
Category 1: Liquid Flow Calibration Systems
Liquid flow calibration systems are used to verify and calibrate flow meters intended for liquid media. Xinya’s liquid calibration systems are generally grouped into two configurations:
- Laboratory systems: typically covering DN6–DN150
- Industrial systems: typically covering DN15–DN1000
Applicable system uncertainty:
- Laboratory systems: up to ≤0.05%
- Industrial systems: up to ≤0.2%
These uncertainty values represent the achievable range under specified system conditions and configuration, not a fixed guarantee across all setups.
Category 2: Gas Flow Calibration Systems
Gas flow calibration systems are used for verifying gas flow meters using methods such as:
- Venturi sonic-nozzle method
- Reference-meter based method
Typical coverage:
- DN15–DN300
- Applicable uncertainty: up to ≤0.3% under system conditions
These systems are generally referenced against ISO 9300 (critical flow Venturi nozzles) and applicable Chinese national standards for gas flow measurement, where relevant to the sonic-nozzle method.
Liquid vs Gas Flow Calibration Systems Comparison
| Parameter | Liquid Flow Calibration System | Gas Flow Calibration System |
|—|—|—|
| Calibration Method | Static mass method, master meter method | Sonic-nozzle (Venturi) method, reference-meter method |
| Typical Size Range | DN6–DN150 (lab) / DN15–DN1000 (industrial) | DN15–DN300 |
| Applicable Uncertainty | ≤0.05% (lab) / ≤0.2% (industrial) | ≤0.3% |
| Reference Standards | Applicable Chinese metrology standards | ISO 9300 and applicable Chinese standards |
| Typical Use Case | Water, chemical liquids, oil-based fluids | Natural gas, fuel gas, air/gas media |What Determines the Final System Configuration
Xinya does not offer a single fixed calibration system model. The actual configuration supplied depends on several buyer-specific factors:
- Medium to be calibrated (liquid or gas type)
- Flow range required
- Meter size (DN range)
- Meter type to be tested
- Required measurement uncertainty
- Calibration method requested (e.g., static mass, master meter, sonic nozzle)
- Testing procedure or protocol required by the buyer
- Any additional customer-specific technical requirements
Because these variables directly affect tank size, piping design, reference standards, data acquisition setup, and automation level, two calibration systems built for different customers are rarely identical.
Information Buyers Should Prepare Before Requesting a Quote
To receive an accurate technical proposal, buyers are generally expected to provide:
- Type of medium (liquid type or gas composition)
- Required flow range (minimum and maximum)
- Meter sizes and types to be calibrated
- Required calibration uncertainty
- Preferred or required calibration method
- Any applicable national or industry testing standard
- Site conditions relevant to installation (if known)
Frequently Asked Questions
Does Xinya manufacture flow meters as well as calibration systems?
Yes. Xinya manufactures flow meters (including electromagnetic, turbine, vortex, and gas-type meters) and separately manufactures flow calibration systems used for verifying such meters.What is the difference between laboratory and industrial liquid calibration systems?
Laboratory systems generally cover smaller diameters (DN6–DN150) with tighter uncertainty (up to ≤0.05%), while industrial systems cover larger diameters (DN15–DN1000) with uncertainty up to ≤0.2%, depending on configuration.What calibration method is used for gas flow systems?
Gas flow calibration systems from Xinya are based on the sonic-nozzle (Venturi) method and reference-meter based methods, referencing ISO 9300 and applicable Chinese standards where relevant.Can Xinya guarantee a specific uncertainty value for every project?
Uncertainty figures listed are applicable under specified system conditions and configuration. Final achievable uncertainty depends on the actual system design agreed upon with the buyer.Does Xinya use its calibration systems for its own products?
Xinya operates its own calibration facilities for internal factory measurement and verification purposes.Summary
Xinya Instrument manufactures two main categories of flow calibration systems: liquid flow calibration systems (laboratory and industrial configurations) and gas flow calibration systems based on sonic-nozzle and reference-meter methods. Actual system specifications vary by medium, flow range, meter type, required uncertainty, and customer testing requirements. Buyers seeking a calibration system should provide these technical details to receive an accurate, project-specific configuration rather than relying on a single standardized model.
