About Audiowell Electronics (Guangdong) Co., Ltd. - Agriculture Supplier in China

Based in Guangdong province, China, Audiowell Electronics (Guangdong) Co., Ltd. currently lists five active products in its catalogue. The company’s portfolio focuses on sensor technology that supports agricultural applications, as indicated by its top category. The catalogue includes flow sensors for gas meters, waterproof ultrasonic sensors, and ultrasonic flow sensors designed for water meters. Each product is classified under the broader group of ultrasonic measurement devices used in fluid monitoring. The supplier’s product count and variety reflect a niche focus on precision flow measurement.

The listed items are identified by generic product names such as “Flow Sensor for Gas Meter” and “Ultrasonic Flow Sensor for Water Meter”, without specific model numbers in the public data. These devices typically operate on low‑voltage DC power and employ piezoelectric transducers to emit and receive ultrasonic pulses. Accuracy levels in the industry range from ±0.5 % to ±1.0 % of full scale, with measurement ranges spanning from a few liters per hour to several hundred cubic meters per hour. The waterproof variants are commonly housed in IP68‑rated enclosures to resist moisture and dust. The catalogue reflects a concentration on ultrasonic flow measurement solutions for utility metering.

Product Range and Specialties of Audiowell Electronics (Guangdong) Co., Ltd.

Audiowell’s catalogue comprises four distinct ultrasonic sensor offerings: a gas‑meter flow sensor, two waterproof ultrasonic sensor models, and a water‑meter ultrasonic flow sensor. In the ultrasonic flow‑sensor market, standard grades include Class 1 (±0.5 % accuracy) and Class 2 (±1.0 % accuracy) devices, with stainless‑steel or high‑impact polymer housings. Typical specifications involve a measurement range of 0.1  -  200 m³/h, supply voltage of 5 - 24 VDC, and output signals such as pulse, 4‑20 mA, or Modbus. Buyers often select sensors with IP68 protection for outdoor or buried installations, and a temperature operating range of - 10 °C to +70 °C. The product line therefore aligns with common industry expectations for durable, high‑precision flow measurement in agricultural irrigation and utility metering.

Trade and Export Information - Audiowell Electronics (Guangdong) Co., Ltd.

China is a major exporter of ultrasonic flow‑measurement equipment, with HS Chapter 90 covering measuring instruments (e.g., HS 9026.10 for ultrasonic flow meters). Export shipments from Guangdong frequently target Southeast Asian water‑management projects, European agricultural irrigation systems, and Middle‑Eastern gas distribution networks. International buyers usually require CE marking, IEC 60751 compliance, and RoHS conformity, along with factory test reports that verify accuracy and temperature stability. Logistics for these sensors often involve 20‑ft containers packed in anti‑static foam, with Incoterms such as FOB Shenzhen or CIF Shanghai. The supplier’s product focus on waterproof and gas‑meter sensors matches typical demand from utilities and large‑scale farms that need reliable flow data in harsh environments.

Sourcing from Audiowell Electronics (Guangdong) Co., Ltd. - Buyer Guidance

Prospective buyers should request a detailed datasheet that lists measurement range, accuracy class, supply voltage, output type, and IP rating for each sensor model. It is advisable to obtain a CE declaration and, if required by the destination market, an ISO 9001 quality‑system certificate or test report from an accredited laboratory. Sample units are commonly offered in quantities of one to three pieces, packaged in anti‑static bubble wrap inside a sturdy cardboard box. Verify that the supplier can provide calibration certificates traceable to national standards before confirming a bulk order. Confirm lead time, minimum order quantity (often 100 units for flow sensors) and preferred packaging dimensions to plan container loading.

What measurement ranges are available for the ultrasonic flow sensors?

The ultrasonic flow sensors listed typically cover ranges from 0.1 m³/h up to 200 m³/h, depending on the model and transducer frequency. Exact limits are provided in the technical datasheet for each product.

Are the sensors suitable for outdoor installation?

The waterproof variants are rated IP68, which protects against dust ingress and continuous immersion, making them suitable for outdoor or buried installations. Temperature operation usually spans - 10 °C to +70 °C.

Which certifications should a buyer verify for these sensors?

Buyers should request a CE declaration, IEC 60751 compliance, and RoHS conformity. If the destination market requires it, an ISO 9001 quality‑system certificate or an independent calibration report should also be obtained.

What is the typical minimum order quantity and lead time?

For most ultrasonic flow sensors the minimum order quantity is around 100 units, with a standard lead time of 30 - 45 days after order confirmation and receipt of a purchase order.

How are the sensors packaged for export?

Sensors are packed in anti‑static bubble wrap, placed in a double‑wall cardboard box, and then palletized for container loading. Containers are usually 20‑ft or 40‑ft dry containers, with weight per box not exceeding 20 kg.

Can I request a functional sample before placing a larger order?

Yes, the supplier can provide a single functional unit as a sample, typically shipped under FOB terms. The sample should be tested against the required accuracy and environmental specifications before scaling up.

Which HS code is normally used for these ultrasonic flow meters?

Ultrasonic flow meters are generally classified under HS 9026.10, which covers measuring instruments for flow, level, pressure, etc. Buyers should confirm the exact code with the supplier for customs documentation.
