About Henan Changrun Automation System Co., Ltd - Industrial Valves & Gauges Supplier in China

China hosts 22 active product listings from Henan Changrun Automation System Co., Ltd. The catalogue spans satellite receivers, electric and electronic sensors, GPS navigation devices, industrial valves and gauges, as well as a selection of agricultural tools. Product titles include high‑temperature pressure liquid level meters, multiple series of fuel level sensors (Cr‑606, Cr‑6061‑3, Cr‑6061‑2, Cr‑6062, Cr‑607), magnetic‑strictive and side‑mounted magnetic flap level gauges, boiler level gauges (Cr‑6032, Cr‑6033), and diagnostic tools such as a Debug Tool and a GPS All‑in‑One machine. Each entry belongs to HS‑code families for measurement instruments (typically 9026), navigation equipment (8526), and industrial valves or gauges (8481), reflecting the technical nature of the offerings.

The supplier’s catalogue is organized under six top categories, with a particular focus on level measurement and sensor technology. Items such as the Cr‑6011 cable‑type water level gauge and the Cr‑uhz side‑mounted magnetic flap gauge illustrate the range of liquid‑level instrumentation, while the Cr‑606 series fuel level transmitters address automotive and gas‑station applications. The inclusion of a GPS product (labelled simply “Gps”) and a Cr606g GPS All‑in‑One machine indicates capability in satellite navigation hardware. Overall, the 22 listed items provide a cross‑section of electronic sensing and industrial gauge solutions that are common in automation and process‑control markets.

Product Range and Specialties of Henan Changrun Automation System Co., Ltd

Henan Changrun’s product list concentrates on liquid‑level measurement devices and related sensor technology. The Cr‑606 series, for example, includes capacitance, ultrasonic and magnetic‑flap variants that are used to monitor fuel, lubricant and water levels in tanks, with typical accuracy ranges of ±0.5 % of full scale and operating temperatures up to 85 °C. Magnetic‑strictive gauges such as the Magneto‑strictive Liquid Level Gauge generally offer a resolution of 1 mm and are compatible with stainless‑steel or brass housings. Boiler level gauges (Cr‑6032, Cr‑6033) are designed for industrial steam systems and often meet DIN 28030 specifications for pressure‑rated gauges. GPS and satellite receiver units fall under the 8526 HS chapter, where buyers normally expect compliance with CE and FCC standards and a positioning accuracy of 2 - 5 m for civilian‑grade devices. Diagnostic tools like the Debug Tool are typically used for firmware verification and may support USB or CAN interfaces.

Trade and Export Information - Henan Changrun Automation System Co., Ltd

Exporters of industrial sensors and level gauges from China usually ship to buyers in Southeast Asia, the Middle East, Europe and North America, where process‑automation, oil‑&‑gas and automotive sectors demand reliable measurement equipment. HS‑code 9026 (instruments for measuring or checking the flow, level, pressure of liquids or gases) and HS‑code 8481 (valves, taps, cocks) dominate customs declarations for the listed items, while navigation devices are classified under HS‑code 8526. Commonly required certifications for these categories include ISO 9001 quality‑management, CE marking for EU markets, RoHS compliance for electronic components, and where applicable ATEX certification for hazardous‑area installations. Freight is typically arranged in 20‑ft or 40‑ft containers with anti‑static packaging for electronic sensors, and wooden crates with moisture‑absorbing liners for gauge assemblies. Incoterms such as FOB Shanghai or CIF destination port are standard in Chinese export contracts for these product families.

Sourcing from Henan Changrun Automation System Co., Ltd - Buyer Guidance

When sourcing level transmitters or gauges from Henan Changrun, buyers should request the latest type‑test report, calibration certificate (often a NIST‑traceable report) and a material safety data sheet for any sealing compounds. For GPS and satellite receiver units, a CE Declaration of Conformity and a test report confirming compliance with ITU‑R Radio Regulations are typical prerequisites. Verify that the supplied specifications list measurement range, accuracy class (e.g., Class 0.5 % FS), operating temperature limits and connection type (4‑20 mA, Modbus, HART) before confirming order quantities. Samples of representative models are usually provided in small‑pack cartons; examine the sample for sensor response time and gauge linearity, and compare the test data with the supplier’s documentation to confirm consistency.

What product categories does Henan Changrun Automation System Co., Ltd list?

The supplier lists liquid‑level meters, fuel and lubricant level sensors, magnetic‑flap and magneto‑strictive gauges, boiler level gauges, pressure transmitters, GPS navigation units, and diagnostic/debug tools.

How many distinct products are active in the catalogue?

The catalogue contains 22 distinct product entries covering sensors, gauges and navigation equipment.

Which HS‑code families are relevant for these items?

Typical HS codes are 9026 for measurement instruments, 8481 for industrial valves and gauges, and 8526 for satellite navigation and GPS devices.

What certifications should a buyer ask for before purchasing?

Buyers normally request ISO 9001, CE marking, RoHS compliance and, for hazardous‑area gauges, ATEX certification or equivalent test reports.

What technical specifications are standard for the Cr‑606 fuel level transmitters?

Cr‑606 transmitters usually offer a measurement range of 0 - 100 % fuel level, accuracy of ±0.5 % FS, temperature operation from - 40 °C to +85 °C and output signals such as 4‑20 mA or Modbus.

What packaging and shipping methods are typical for these products?

Electronic sensors are packed in anti‑static bags within sealed cartons; larger gauges are crated with wooden frames and moisture‑absorbing packs. Shipments are commonly sent in 20‑ft or 40‑ft containers under FOB or CIF terms.

How can a buyer verify the performance of a liquid level gauge?

Request the calibration certificate and a recent type‑test report, then compare the gauge’s linearity, repeatability (often ≤0.2 % of full scale) and response time with the documented values.

What lead time and minimum order quantity are typical?

Suppliers in China generally quote a lead time of 15‑30 days for standard models and may set a minimum order quantity of one full container load (approximately 500‑800 units depending on size).
