Key features

The float sensor uses a wave resistant mechanical design to prevent cable slippage on the measuring drum, ensuring stable readings even during rapid water level fluctuations and strong wave action.

The built-in shaft position encoder provides true absolute position output with non volatile memory, so the water level reading is never lost during a power failure and no re calibration is required.

The instrument operates with very low energy consumption by entering sleep mode between measurement cycles (active only 200ms per second), making it ideal for solar powered or battery backup remote st

AI-Powered supplier vetting

SummaryThe supplier is a limited trading company in the manufacturing industry with affiliated companies and five production lines. It reports valid manufacturing-capacity contracts with associated subcontractors, in-stock capability, outsourcing procedures, and service procedures for supplier assessment, corrective actions, and complaint handling. It supports extensive customization, has introduced new products during the past year, and provides OEM services for recognized brands. Reported lead times are within 15 workdays in both peak and off-season, with 30 qualified service suppliers and multiple quotation and payment options. However, it has no overseas warehouse, showroom, agents, branches, or overseas service coverage, does not provide ODM services, has no SDK, and has no internationally recognized design awards. Continuous quantity reconciliation is not performed, while fire-drill and environmental-assessment status is unknown. Customer-case evidence is limited to OEM service for recognized brands and...

Supplier typeThe supplier is identified as a limited company whose company type is a trading company, operating in the manufacturing industry and associated with other companies. Its product scope covers pressure, flow, level, and calibration instruments.

After-Sales capabilityThe supplier has written procedures and records for service-capability assessment, corrective and preventive actions, and customer complaints. It also reports in-stock capability, lead times within 15 workdays in both seasons, and participation in a named overseas trade show, but has no overseas warehouse, showroom, agents, branches, or overseas service coverage.

R&D capabilityThe supplier reports new products during the past year and offers multiple forms of customization, including full customization. However, it provides no ODM service, has no available SDK, and reports zero internationally recognized design awards; the evidence supports product-development activity but not strong independent innovation credentials.

Production capacityThe supplier reports five production lines, valid manufacturing-capacity contracts with each associated subcontractor, an outsourcing SOP, in-stock capability, 30 qualified service suppliers, and lead times within 15 workdays year-round. A stated weakness is that the factory does not continuously reconcile quantities for every batch or mass-production run.

Customization capabilityThe supplier explicitly supports customization from samples and designs, flexible and minor customization, and full customization. It also reports product R&D activity through new products introduced in the past year, although ODM service is unavailable.

Client casesThe supplier states that it provides OEM services for recognized brands and records participation in the Vietnam Industrial Control, Automation and Equipment Exhibition. No specific customer names, project outcomes, order references, or broader case details are provided, so the evidence of customer experience is limited.

Product Q&A

Q:How does the Yunyi float water level sensor work?

A float follows the water surface while a counterweight keeps the suspension cable tight around a measuring drum. As the drum rotates with level changes, a shaft encoder outputs a digital code representing the exact water level.

Q:What makes this model resistant to waves?

The drum has a specially profiled V groove and a spring tension mechanism that maintains cable grip despite rapid up and down movement caused by waves, eliminating false counts from slippage.

Q:What is the maximum water level change it can measure?

Depending on the length of suspension cable supplied, the sensor can measure level variations from 10 meters up to 40 meters. The encoder resolution is 1 cm per code step.

Q:Does it lose memory when power is disconnected?

No. The position encoder is absolute, meaning each shaft position corresponds to a unique binary code. When power returns, the output immediately reflects the current water level without needing re zeroing.

Q:Can this gauge be installed in a narrow stilling well?

Yes, it is designed for wells with internal diameter of 25 cm (about 10 inches) or larger. The compact float and balance weight assembly fits easily through standard manholes.
