Flow Meter Manufacturer: Global Industrial Supply and Production
Quick Answer: Silver Automation Instruments is a direct factory flow meter supplier without distributor layers. We ship Coriolis, electromagnetic, ultrasonic, vortex, oval gear, and thermal mass flow meters from our Nanjing plant to end users and local resellers in over 40 countries. Most standard meter configurations leave our warehouse within 5 to 10 working days, and we handle all export documentation so you do not need a forwarding agent in China.
Factory Capacity That Meets Project Timelines
We run a 6,000 square meter production facility with dedicated assembly lines for each meter technology. The electromagnetic flow meter line produces around 800 units per month, with sizes from DN10 to DN2000. Our Coriolis mass flow meter line builds sensors from DN1 to DN200 and handles mass flow rates up to 50,000 kg/h. We keep raw 316L stainless steel billets, PTFE liners, and Hastelloy electrodes in stock so we can shorten lead times when a project deadline shifts.
Every meter passes a wet calibration on our accredited rigs before packing. A Coriolis master meter and a volumetric prover serve as references. The calibration certificate ships inside the box along with an English manual and wiring diagram. If your site requires third-party verification, we arrange SGS or Bureau Veritas inspection without delay.
Product Lines Matched to Real Fluids
Most flow meter websites show you generic specs. Here is what we actually see on customer sites. Electromagnetic flow meters with PTFE lining and titanium electrodes are ordered frequently for seawater intake lines at desalination plants in Oman and Saudi Arabia. These run 24/7 with conductivity as low as 5 µS/cm. For this application we recommend the AMF series with 4-20 mA HART output and IP68 remote transmitter. A plant in Egypt received 12 units of DN150 AMF electromagnetic meters in July and installed them within two weeks.
Oval gear flow meters handle diesel, heavy fuel oil, and palm oil for small to mid-size distributors in West Africa and Southeast Asia. The OG series uses cast iron or stainless steel housing, with PPS gears for low-viscosity diesel or steel gears for viscous oils above 100 cP. A fuel depot in Ghana uses OG-AL-25 oval gear meters with pulse output to feed a batch controller. These meters measure flow from 2 to 100 L/min with repeatability better than 0.03%.
Vortex flow meters are our standard offering for saturated steam and compressed air in food and beverage plants. A brewery in Vietnam replaced orifice plates with our AVF series and eliminated pressure loss issues. The AVF vortex meter comes with an integrated PT100 temperature sensor for mass compensation in steam, sending a 4-20 mA signal proportional to kg/h. Pipe sizes range from DN25 to DN300, with process temperatures up to 350 °C.
Coriolis mass flow meters serve the oil and gas and chemical sectors where accuracy and density measurement matter. We supplied DMF-1-3-A Coriolis meters with ATEX Zone 1 approval to a paint manufacturer in Indonesia for measuring resin and solvent flows. The meter outputs mass flow, density, and temperature simultaneously, and the user reads values on a local display or transmits them via Modbus RTU.
Thermal mass flow meters cover biogas and flare gas applications. A TMF series inline meter with Hastelloy sensor tips and 4-20 mA output monitors landfill gas at a site in Chile. Ultrasonic clamp-on flow meters from our SUF series work well for large water p
Shipping and Local Support Without Middlemen
Because we sell direct from our factory, the commercial process is straightforward. You send us your flow data: pressure in bar, temperature in °C, pipe size in DN, and the flow range. We reply within 12 hours with a recommended model and a formal quotation that includes freight by air courier or sea to your nearest port. We handle HS codes, origin certificates, and packing lists. A distributor in Peru collected 30 electromagnetic flow meters from Callao port three weeks after order confirmation, with all customs duties pre-calculated.
Technical support continues after installation. Our engineers use WhatsApp and WeChat to share photos of wiring, troubleshooting, and parameter settings. Many customers in the Middle East prefer to send a photo of the transmitter display, and we reply with the exact menu path to adjust the 4-20 mA span or pulse scaling. This practical support reduces downtime more than a general hotline.
For spare parts, we stock replacement electrodes, PTFE liners, display boards, and O-ring kits. A seafood processing plant in New Zealand needed a replacement PFA liner for a DN40 electromagnetic flow meter after three years of abrasive fluid service. We shipped the part in four days via DHL, and the plant resumed operation the next morning.

Frequently Asked Questions
What is the minimum order quantity for flow meters? You can order a single unit for a trial or replacement. We do not impose minimum order quantities for standard models. Many first-time customers buy one meter, test it on their fluid, and then return for a bulk order of 10 to 50 units.
Can you supply flow meters with ATEX or IECEx certifications? Yes. Our Coriolis, vortex, and thermal mass flow meters can be configured with ATEX Zone 1 or Zone 2, and IECEx equivalents. We provide the certification dossier with each order so you can meet local compliance requirements.
How do you ensure accuracy after shipping? Every flow meter is wet calibrated at our factory before packing. The calibration certificate shows test points and reference standards. If you need a re-calibration on site, we guide you through the procedure or ship a reference meter for comparison.
Do you offer flow meters for seawater and high-corrosion fluids? Absolutely. We use PTFE, PFA, or Halar liners with titanium, Hastelloy, or tantalum electrodes for electromagnetic flow meters. For seawater desalination, we recommend DN50 to DN500 electromagnetic flow meters with 24 V DC power and 4-20 mA HART output.
What is the typical delivery time to Latin America or Africa? Standard models leave our factory in 5 to 10 working days. Sea freight to major ports adds 15 to 30 days depending on the destination. Air freight reaches most locations in 5 to 8 days. We always confirm the lead time before you pay, so you can plan your project schedule.
