Flow Meter China Manufacturer Directory: High-Quality Sourcing Guide for Flanged Magmeters
Quick Answer: Flanged magmeters are the safest choice for most process lines from DN15 to DN2000. Silver Instruments manufactures flanged electromagnetic flow meters in China with PTFE or rubber lining, 316L electrodes, and 4-20 mA HART output.

Why Flanged Magmeters Dominate Process and Utility Lines
Flanged connections match the piping standards most plants already use. DIN, ANSI, and JIS flanges are common in our export markets. A flanged magmeter installs between two flanges on a pipe run. The body sits rigid. There is no need to cut threads or weld adapters. This saves installation time on site.
In practice, most engineers choose flanged magmeters for water lines, chemical dosing, and effluent flow. The flanged design handles higher pressure than wafer types. We see this on customer sites in Vietnam, Indonesia, Saudi Arabia, and Mexico. A water utility in Vietnam ordered DN150 and DN200 flanged magmeters for a desalination plant expansion. They needed PN16 flanges and hard rubber lining for seawater.
Parameters That Decide a Flanged Magmeter Quote
You can shortlist suppliers faster if you send these six data points. Pipe size, fluid, pressure, temperature, flow range, and power supply. For example, a dairy plant in Australia may need a DN40 flanged magmeter with 316L electrodes and food grade PTFE lining. A chemical plant in the Philippines may need a DN80 unit with PVDF lining and optional grounding rings.
Here is the thing. Most price differences come from the liner and electrode material. PTFE and PFA suit aggressive chemicals and higher temperatures up to 120 °C. Hard rubber is lower cost and works well for water and wastewater. Neoprene suits weak acids and alkalis. 316L electrodes cover most clean liquids. Titanium or tantalum electrodes work for seawater and chlorinated systems but cost more.
Accuracy, Output, and Installation Details
Flanged magmeters from Silver Instruments offer 0.5 percent accuracy as standard. An optional 0.2 percent version is available for billing and custody transfer. Output options include 4-20 mA, pulse, RS485 Modbus, and HART. Most engineers specify 4-20 mA HART for integration with PLC or SCADA systems.
Installation requires a straight run. We recommend 10D upstream and 5D downstream where possible. The pipe must stay full. The electrode plane must remain horizontal for fluids with solids or air bubbles. Grounding rings are often needed on plastic or lined pipes. We have seen this overlooked on customer sites many times.
Price Ranges and Lead Times
Small flanged magmeters from DN15 to DN50 typically start around USD 300 to USD 600 depending on liner and electrode. DN80 to DN200 units may range from USD 600 to USD 1500. Large sizes above DN300 go up based on flange rating and material. These are budget figures, not a formal quotation. Your exact price depends on volume and optional certifications.

How to Check a Supplier Before You Pay
Ask for a test report and calibration certificate. Ask which flow standard the factory uses. Ask if the supplier can provide third party inspection. Silver Instruments calibrates every flanged magmeter on a certified rig before packing. We send photos and test data with the shipping documents.
Most engineers skip the part about flange standards. Confirm whether the unit matches DIN, ANSI, or JIS before ordering. A mismatch means extra adapters on site. Also confirm the display language and engineering units. We configure units to show m3/h, L/s, or gpm based on your plant standard.

FAQ: Five Questions Engineers Ask Before Buying
Question: What is the minimum fluid conductivity for a flanged magmeter?
Answer: Standard units need at least 5 µS/cm. For demineralized water or very low conductivity fluids, ask us to confirm a special electrode design.
Question: Can a flanged magmeter measure corrosive chemicals?
Answer: Yes. Choose PTFE or PFA liner with titanium or tantalum electrodes. Send us the chemical name and concentration so we can check compatibility.
Question: Which flange standards do you offer?
Answer: DIN, ANSI, and JIS are common. Other standards are available on request. Specify the standard and pressure rating when you send your inquiry.
Question: Do flanged magmeters need grounding rings?
Answer: Metal pipes usually do not need grounding rings if the meter body is grounded. Plastic or lined pipes often need grounding rings or a grounding electrode.
Question: What is the typical accuracy of a flanged electromagnetic flow meter?
Answer: Standard accuracy is 0.5 percent of reading. An optional 0.2 percent version is available for billing applications.
