Does the flow meter require straight pipe sections?

It has a lower requirement for straight pipeline sections compared to other types, as there are no obstacles in the pipe causing pressure loss.

What power supply options are available?

The flow meter can be powered by 110-240V AC, 24V DC, or battery, offering flexibility for different installation environments.

What is the operating temperature range?

The standard operating temperature range is -20 to +120 degrees Celsius, depending on the selected liner and electrode materials.

AI-Powered supplier vetting

SummaryYantai Auto Instrument Making Co., Ltd. is a China-based limited company established in 1994 and operating in Shandong. It presents itself as a manufacturer of pressure transmitters, flow meters, level instruments, and related products, with design, R&D, production, sales, OEM customization, and maintenance activities. The supplier reports ISO9001:2015, ISO14001:2015, and ISO45001:2016 certifications, six production lines, advanced production and calibration equipment, and export activity since 2015. Evidence supports manufacturing capability, product-related technical specialization, and imported-brand maintenance services. However, the available information does not sufficiently establish financial strength, the scale or effectiveness of after-sales service, verified innovation performance, or a broad customer portfolio. One recorded buyer is SVAAR PROCESS SOLUTIONS PRIVATE LIMITED, and shipment records identify Shanghai as an origin port.

Supplier typeThe supplier is identified as a Chinese limited company and qualified source manufacturer specializing in pressure transmitters and flow meters. Its stated activities cover product design, R&D, production, sales, OEM customization, and self-managed export, indicating a manufacturer rather than only a trading intermediary.

CertificationsThe supplier reports holding ISO9001:2015, ISO14001:2015, and ISO45001:2016 management-system certificates. These explicitly demonstrate certifications in quality, environmental, and occupational health and safety management.

After-Sales capabilityThe supplier states that it undertakes maintenance for Rosemount, Yokogawa, Honeywell, and other imported-brand pressure, differential-pressure, and liquid-level transmitters. This supports the existence of relevant maintenance capability, although the scope, response performance, and service coverage are not provided.

Production capacityEvidence indicates a physical factory in Yantai, six production lines, advanced production and calibration equipment, and product coverage spanning pressure, flow, and level instruments. The supplier also claims integrated design, R&D, production, and sales operations, supporting a positive assessment of manufacturing capability.

Customization capabilityThe company background explicitly states that it provides OEM customization, while its product scope includes multiple instrument categories and configurations such as remote diaphragm-seal pressure transmitters and different flow-meter types. This supports customization capability, although specific customization limits and delivery performance are not stated.
