How should the sensor be maintained to prevent blockage?

Clean the pre-filter monthly and blow dry with nitrogen in both directions for at least 30 minutes during shutdown to prevent contamination and blockage.

AI-Powered supplier vetting

SummaryThe supplier is a combined business engaged in instruments, meters, industrial automation equipment, electronic and electromechanical products, chemical products, and technical services. It reports substantial product output, inventory capability, valid manufacturing contracts with associated subcontractors, and export markets across South America, Europe, Australia, North America, and domestic markets. Customization, ODM, and OEM services are available, with new products reported during the past year. Service management includes documented procedures for supplier assessment, corrective and preventive actions, and complaint handling. However, no overseas warehouse, showroom, agents, branches, or SDK is available. Certification information, explicit customer case details, and verified financial results are not provided.

Supplier typeThe supplier is identified as a combined company whose business scope covers instruments and meters, industrial automatic equipment, electronic and electromechanical products, chemical products, sales, and technical services. This provides explicit evidence of a diversified industrial supplier profile.

After-Sales capabilityThe supplier reports documented and followed procedures for service assessment, corrective and preventive actions, and customer complaint handling, as well as inventory capability and lead times within 15 working days. However, it lacks overseas warehouses, showrooms, agents, and branches, which limits demonstrated overseas service infrastructure.

R&D capabilityThe supplier reports new products during the past year, provides ODM services, and supports multiple forms of customization. It does not have an available SDK, so its innovation capability is demonstrated through product development and design services rather than SDK support.

Production capacityReported annual output includes 20,000 flow meters, 5,000 pressure-sensor boxes, 15,000 metering pumps, and 5,000 level meters. The supplier also reports CNC and automatic lathing facilities, inventory capability, valid contracts with associated subcontractors, 80 qualified service suppliers, and lead times within 15 working days.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also reports ODM capability, providing strong direct evidence of broad customization coverage.

Product Q&A

Q:What causes display exceptions or a black screen?

Common causes include power failure, unstable voltage, internal circuit damage, loose display pins, or reversed DC24V polarity. Solutions involve checking power connections, verifying polarity, reseating pins, or contacting the manufacturer for repair.

Q:Why might the instantaneous flow show anomalies or zero?

This can be caused by reversed probe direction, dirty sensors, incorrect parameter settings, or flow field disturbances. Fix by correcting probe direction, cleaning sensors, adjusting parameters, and ensuring an upstream straight pipe section of at least 5D.

Q:What leads to large reading deviations in measurement accuracy?

Deviations often result from changes in gas composition, temperature/pressure fluctuations, sensor contamination, or improper installation. Recalibrate the instrument, clean the sensor, and ensure installation at the pipeline center.

Q:How to resolve abnormal 4-20mA output?

Check for range setting errors, wiring loop issues, or converter failure. Verify range configuration, eliminate interference in wiring, and contact the supplier if the converter needs repair.

Q:What causes slow response speed or unstable flow control?

Slow response is due to sensor aging or processing delays; unstable control stems from low air pressure, loose connectors, or faulty valves. Solutions include replacing the sensor, upgrading firmware, stabilizing pressure, and repairing valves.
