AI-Powered supplier vetting

SummarySHANDONG RENKE CONTROL TECHNOLOGY CO., LTD. is identified as a Jinan-based trading company operating in manufacturing-related industries, including integrated circuits and environmental monitoring instruments. The supplier reports ISO9001:2015, RoHS, CE, and FCC certifications. It provides extensive customization and ODM services, has introduced new products within the past year, and reports OEM service for well-known brands. Production-related information includes sensor productivity of 400,000 pieces and five quality inspectors, although finished-product inspection has instructions but no written records. The supplier lacks inventory, overseas warehouses, overseas agents or branches, and a valid manufacturing-capacity contract with affiliated subcontractors. Financial records are referenced for 2022–2024, but no monetary figures or detailed financial indicators are provided. Customer evidence is limited to one associated buyer name and does not establish the scope or quality of completed projects.

CertificationsThe supplier reports an ISO9001:2015 certificate and product certifications including RoHS, CE, and FCC. These certifications explicitly support quality-management and product-compliance capability.

After-Sales capabilityThe supplier reports no inventory capability, no overseas warehouse, no overseas showroom, and no overseas agents or branches. It also reports serving zero countries overseas, so the provided evidence does not demonstrate strong after-sales coverage, particularly internationally.

R&D capabilityThe supplier reports new products within the past year, provides ODM services, and offers customization from samples, designs, and full specifications. However, it reports no available SDK, so innovation capability is supported in product development and design services but not across all technical-development resources.

Production capacityThe supplier reports sensor productivity of 400,000 pieces, five quality inspectors, and production equipment including an MST mounter and auto-soldering and soldering capabilities. Nevertheless, it has no valid manufacturing-capacity contract with affiliated subcontractors, and its inspection and supplier-assessment procedures lack written records, limiting assurance of production control.

Customization capabilityBoth reported design-service fields list customization from samples, designs, full customization, minor customization, and flexible customization. The supplier also reports ODM capability, providing explicit evidence of broad customization support.

Product Q&A

Q:Where is this Doppler ultrasonic flow meter used?

It is primarily used in open irrigation channels, municipal sewer pipes, and hydrological basins. It is particularly suitable for monitoring low water levels; the water level should ideally be at least 20 centimeters, with the sensor submerged by at least 5 centimeters. In standard pipes and channels, water depth is measured using a pressure Doppler flowmeter, while flow velocity is measured using an ultrasonic Doppler flowmeter, and flow rate is calculated from these measurements.

Q:How should a Doppler flow meter be installed downstream of a gate or pump?

If installed downstream of a gate, pay special attention to the water surface to ensure it is stable. If the Doppler flowmeter is installed at a distance from the gate equal to 30 times the channel width, but the water surface remains unstable, increase the distance between the device and the gate until the flow stabilizes. There is no limit to this distance; it could be 60 times the channel width, 80 times the channel width, or more, until the flow stabilizes.
