Magnetic Flow Meter Suppliers: Authorized Industrial Instrument Distributors
Quick Answer: Silver Automation Instruments is an authorized industrial instrument distributor and supplier of electromagnetic flow meters for water, wastewater, chemical, food and beverage, mining, and desalination applications. We stock sizes from DN10 to DN2000 with PTFE, rubber, and PFA liners. Send your pipe size, fluid, temperature, pressure, and flow range to get a price and data sheet within one working day.
What an Authorized Magnetic Flow Meter Supplier Should Provide
An authorized supplier holds a direct distribution agreement with a factory. That means the factory honors the warranty, the calibration certificate carries traceability, and you do not deal with a trading company that may change prices or change models from batch to batch. We sell under the Silver Automation Instruments brand and supply the complete product file with each order. The file includes the calibration certificate, material certificates for wetted parts, and a user manual in English.
Most engineers skip this part. The factory authorization matters when you need repeat orders, spare parts, or a service visit. A non-authorized trader can sell you the same model once. But if you need a replacement electrode or a matched transmitter board two years later, the factory will not support a unit from an unknown channel.
Magnetic Flow Meter Models and Specs We Stock
We keep standard configurations in stock for DN15, DN25, DN40, DN50, DN80, DN100, DN150, DN200, DN250, and DN300. Larger sizes up to DN2000 are built to order in 15 to 25 days. Standard accuracy is 0.5 percent of reading. For custody transfer or blending, we can supply 0.2 percent accuracy with matched calibration.
Liners include hard rubber for clean water and wastewater. PTFE works for acids and caustics. PFA suits high temperature chemical service. Electrode options include 316L stainless steel, Hastelloy C, tantalum, and titanium. Transmitters support 4-20 mA HART and pulse. RS485 Modbus RTU is available as well. Power is 85 to 265 V AC or 24 V DC. Process temperature can reach 180 °C with a remote mounted transmitter. Minimum fluid conductivity is 5 µS/cm for standard models.
Here is the thing about electrode selection. If the fluid is sodium hydroxide above 20 percent concentration, 316L electrodes can drift. Hastelloy C or nickel electrodes work better. If the fluid is sulfuric acid, tantalum gives good service life. We have seen a paint manufacturer in Southeast Asia replace a 316L meter every eight months until they switched to a Hastelloy C electrode meter. That unit has now run for two years without a failure.
Applications Where Magnetic Flow Meters Fit Best
Magnetic flow meters measure conductive liquids. They do not work for pure oils, gases, or steam. They are a strong fit for raw water intake, treated effluent, sludge, chemical dosing, food ingredients, pulp stock, and mining slurries. We quote these meters most often for desalination plant intake lines, cooling water loops, pharmaceutical water, and brewery CIP return lines.

Pricing and Lead Time
Price depends on diameter, liner, electrode material, and transmitter type. A DN50 standard rubber lined meter with 316L electrodes and compact transmitter is the most economical configuration. A DN100 PTFE lined meter with Hastelloy C electrodes costs more because of the materials. Volume pricing starts at ten units per quarter for distributors in Southeast Asia, the Middle East, Latin America, Africa, and Oceania.
We ship from our factory warehouse in China and we support customers through our Australia site flow-meter.com.au. International orders normally leave within 5 working days for stock models. Custom large diameter meters take 15 to 25 days. We accept bank transfer and payment against proforma invoice. Selected trade terms are available for repeat buyers.
How to Send a Request for Quote
Send us the following data: pipe size (DN), fluid name and concentration, flow range (m³/h or L/h), operating temperature (°C), operating pressure (bar), process connection (flange standard or wafer), and output signal you need. We will return a model, data sheet, and price. If you have an existing meter tag, send the photo of the nameplate so we can match dimensions.

Frequently Asked Questions
Are you an authorized distributor or a factory?
We are the manufacturer and authorized supplier for Silver Automation Instruments magnetic flow meters. You buy direct from the factory and receive a calibration certificate with each unit.
Can you supply magnetic flow meters for seawater?
Yes. We use rubber or PTFE liners with titanium or tantalum electrodes. Seawater desalination plants in the Middle East and Australia use these meters on intake and brine lines. Minimum conductivity is not an issue for seawater.
Do I need a straight run upstream and downstream?
Standard installation requires 5D straight run upstream and 2D downstream for most models. Magnetic flow meters tolerate shorter runs better than orifice plates or vortex meters. If your pipe layout is tight, we can mark the required run on a drawing.
What is the standard accuracy and turndown?
Standard accuracy is 0.5 percent of reading. Turndown ranges from 10 to 1 up to 40 to 1 depending on the transmitter and flow range. We can supply 0.2 percent accuracy for high precision batching applications.
How do I get a price for a DN80 magnetic flow meter?
Tell us the fluid, temperature, pressure, liner preference, and output signal. A simple water meter with rubber liner and 4-20 mA HART output has a different price than an acid meter with PTFE liner and Hastelloy C electrodes. We respond with a quotation within one working day.
