AI-Powered supplier vetting

SummaryThe supplier is identified as a combined company with manufacturing, export, service, quality-control, and R&D capabilities. Evidence shows documented procedures for corrective actions, customer complaints, supplier assessment, and R&D design controls. It provides overseas installation, debugging, maintenance, repair, and training, supported by overseas agents or branches, but has no overseas warehouse or showroom. R&D capabilities include recent product development, ODM/OEM services, 3D design, multiple engineering software tools, and documented design verification activities; however, no SDK is available. Production evidence includes four production lines and stated annual capacities of 500,000 level sensors, 500,000 pressure sensors, and 300,000 flow meters, with lead times within 15 working days in both peak and off-peak seasons. No explicit certification, financial-strength evidence, or named customer cases is provided.

Supplier typeThe supplier is explicitly classified as a combined company rather than an offshore company. Its listed offerings cover manufacturing, export trade, service, quality control, R&D, and sustainable development capabilities, indicating a broad integrated supplier profile.

After-Sales capabilityThe supplier has documented and followed procedures for corrective and preventive actions and customer complaints.

Product Q&A

Q:Which kind of liquid can be measured?

Holykell suggests ensuring medium purity, no dense gas, no suspended solids like crystals, no large sediment deposits at the bottom, and medium viscosity under 10mPa.s. Normal measurement is up to 10mPa.s, while dynamic viscosity over 30mPa.s cannot be measured.

Q:What is the maximum level range?

The UE3001 model supports up to 7 meters, while the UE3003 model supports a range from 5 to 15 meters.

Q:What are the available output signals?

Available outputs include Voltage (1-5V, 0-5V), Current (4-20mA, 0-20mA), and Serial ports (RS485, RS232).

Q:Is the product customizable?

Yes, the product offers full customization including output signals, power supply, temperature range, and IP rating (IP65 to IP68).

Q:What is the response time of the sensor?

The sensor has a response time of less than 200ms to ensure high accuracy and quick readings.
