AI-Powered supplier vetting

SummaryYantai Auto Instrument Making Co., Ltd. is a China-based limited company established in 1994 and operating in Shandong. It presents itself as a manufacturer of pressure transmitters, flow meters, level instruments, and related products, with design, R&D, production, sales, OEM customization, and maintenance activities. The supplier reports ISO9001:2015, ISO14001:2015, and ISO45001:2016 certifications, six production lines, advanced production and calibration equipment, and export activity since 2015. Evidence supports manufacturing capability, product-related technical specialization, and imported-brand maintenance services. However, the available information does not sufficiently establish financial strength, the scale or effectiveness of after-sales service, verified innovation performance, or a broad customer portfolio. One recorded buyer is SVAAR PROCESS SOLUTIONS PRIVATE LIMITED, and shipment records identify Shanghai as an origin port.

Supplier typeThe supplier is identified as a Chinese limited company and qualified source manufacturer specializing in pressure transmitters and flow meters. Its stated activities cover product design, R&D, production, sales, OEM customization, and self-managed export, indicating a manufacturer rather than only a trading intermediary.

CertificationsThe supplier reports holding ISO9001:2015, ISO14001:2015, and ISO45001:2016 management-system certificates. These explicitly demonstrate certifications in quality, environmental, and occupational health and safety management.

After-Sales capabilityThe supplier states that it undertakes maintenance for Rosemount, Yokogawa, Honeywell, and other imported-brand pressure, differential-pressure, and liquid-level transmitters. This supports the existence of relevant maintenance capability, although the scope, response performance, and service coverage are not provided.

Production capacityEvidence indicates a physical factory in Yantai, six production lines, advanced production and calibration equipment, and product coverage spanning pressure, flow, and level instruments. The supplier also claims integrated design, R&D, production, and sales operations, supporting a positive assessment of manufacturing capability.

Customization capabilityThe company background explicitly states that it provides OEM customization, while its product scope includes multiple instrument categories and configurations such as remote diaphragm-seal pressure transmitters and different flow-meter types. This supports customization capability, although specific customization limits and delivery performance are not stated.

Product Q&A

Q:What is the measurement accuracy?

The level measurement accuracy is 0.5%. For flow measurement, standard weir tanks have an accuracy of 1-5%, while non-standard tanks range from 10-30%.

Q:What are the available power supply options?

Standard power is 24VDC. Optional supplies include 220V AC (+15% 50Hz) and 12VDC battery-powered options.

Q:Can this device be used in corrosive environments?

Yes. While ABS is the standard probe material, PTFE material is available for use in corrosive environments.

Q:What communication protocols are supported?

Optional communication interfaces include RS485 and RS232, supporting the MODBUS protocol.

Q:What is the maximum probe cable length?

The standard probe cable length is 10 meters, with a maximum extension up to 100 meters.
