About Kaifeng Hengtian Automation Instrumentation Co., Ltd. - Flowmeter Supplier in China

China hosts a range of industrial instrumentation firms, and Kaifeng Hengtian Automation Instrumentation Co., Ltd. lists five distinct flow measurement devices. The catalogue comprises a Dmf mass flowmeter, an Mfld electromagnetic flowmeter, a Lugb vortex flowmeter, a Lwg intelligent turbine flowmeter, and an Ht-1000b supersonic flowmeter. Each model is classified under the flowmeter product family used for liquids and gases in process industries. The supplier’s listing reflects a focus on electronic and mechanical flow measurement technologies. The catalogue does not specify certifications, so buyers must verify compliance with relevant standards.

Product Range and Specialties of Kaifeng Hengtian Automation Instrumentation Co., Ltd.

The five devices cover the main flow‑measurement principles: a mass flowmeter that typically offers an accuracy of ±0.5 % of full‑scale and a flow range of 0.1‑1000 kg h‑1, an electromagnetic flowmeter designed for conductive liquids with class‑0.5 accuracy and stainless‑steel flow tubes, a vortex flowmeter built to ISO 5167 tolerances for steam and water, an intelligent turbine flowmeter with digital output and resolution down to 0.01 % of reading, and a supersonic (ultrasonic) flowmeter capable of measuring high‑velocity gas streams up to 200 m s‑1. Materials commonly used include 316L stainless steel, Hastelloy, and PVDF liners, and output options span 4‑20 mA, 0‑10 V, and Modbus‑TCP.

Industry standards that buyers usually reference include IEC 60179 for electromagnetic meters, ISO 5167 for vortex meters, IEC 60751 for turbine meters, and IEC 60534‑9‑2 for ultrasonic flowmeters. Typical grades are Class 0.5 for high‑precision applications and Class 1.0 for general‑purpose installations. Buyers often request data sheets that list pressure ratings (up to 25 bar for many models), temperature limits (‑30 °C to +200 °C), and media compatibility charts.

Trade and Export Information - Kaifeng Hengtian Automation Instrumentation Co., Ltd.

Chinese flowmeter exporters commonly serve Europe, North America, the Middle East, and Southeast Asian process industries. The products fall under HS chapter 90 (instruments and apparatus for measuring), and buyers usually require CE marking for the European market, UL certification for the United States, and ISO 9001 quality‑management registration as a baseline. For hazardous‑area installations, IECEx or ATEX certification is frequently requested. Export shipments are typically packed in wooden crates with anti‑static liners, sized for 20‑foot or 40‑foot containers, and Incoterms such as FOB Shanghai or CIF Rotterdam are standard practice.

Regulatory checks often involve customs inspection of the CE Declaration of Conformity and test reports that verify the accuracy class. Chinese manufacturers of flowmeters benefit from established supply chains for stainless‑steel components and calibrated test rigs, which helps meet the tight tolerances demanded by downstream users in oil & gas, water treatment, and chemical processing.

Sourcing from Kaifeng Hengtian Automation Instrumentation Co., Ltd. - Buyer Guidance

When evaluating Kaifeng Hengtian’s flowmeters, request the latest calibration certificate, a CE Declaration of Conformity (or equivalent for the target market), and material certificates for any wetted parts. Verify that the listed accuracy class, pressure rating, and temperature range match the process conditions of the intended installation. Ask for a functional sample or a trial unit; many suppliers accept a minimum order of one unit for testing before larger purchases.

Typical buyer verification steps include checking compliance with IEC standards, confirming that the output signal matches the control system (4‑20 mA, Modbus, etc.), and ensuring that the packaging meets ISO 11607 for protection during sea freight. Lead times for new orders from Chinese flowmeter makers range from 30 to 45 days after receipt of a confirmed purchase order, and MOQ is often set at one unit per model, allowing flexible trial orders.

What flow‑measurement principles are covered by Kaifeng Hengtian’s product list?

The catalogue includes mass, electromagnetic, vortex, intelligent turbine, and supersonic (ultrasonic) flow measurement technologies, each suited to different media and flow‑rate ranges.

Are calibration certificates available for these flowmeters?

Buyers should request the latest calibration certificate from the supplier; calibrated test reports are standard documentation for flow‑meter accuracy verification.

Which certifications should a buyer confirm before importing these instruments?

Typical certifications to request are CE marking for Europe, UL listing for the United States, ISO 9001 quality‑system certification, and IECEx or ATEX if the equipment will be used in hazardous areas.

What are the common output signal options for the listed flowmeters?

Standard outputs include 4‑20 mA, 0‑10 V, and digital protocols such as Modbus‑TCP, depending on the specific model and customer requirement.

What packaging and shipping formats are used for these devices?

Flowmeters are usually packed in anti‑static wooden crates with moisture‑barrier liners, sized for 20‑foot or 40‑foot containers, and shipped under Incoterms such as FOB Shanghai or CIF destination port.

What typical lead time and minimum order quantity apply?

Lead times are generally 30‑45 days after order confirmation, and the minimum order quantity is often one unit per model, enabling trial purchases before bulk procurement.
