Altometer Flow Meter: Sourcing Krohne Industrial Process Induction Spools
Quick Answer: Silver Automation Instruments supplies Altometer compatible electromagnetic flow meters and Krohne style industrial process induction spools for water, wastewater, chemical, food, and marine plants. Send pipe size, liner material, electrode material, pressure, temperature, and flow range for a same day price. Standard sizes from DN15 to DN600 ship from stock or within 3 weeks to Southeast Asia, Oceania, Latin America, the Middle East, and Africa.
Why Buyers Search for Altometer Flow Meter and Krohne Induction Spools
Maintenance teams often need a direct replacement without waiting 8 to 12 weeks for an OEM package. Procurement engineers search for Altometer flow meter sourcing when a plant shutdown is close. They also search for Krohne industrial process induction spools when only the measuring tube is damaged but the transmitter still works. Silver Automation Instruments handles both cases. You can replace the full meter or just source the spool with matching coils and liner.
We have seen this on customer sites many times. A water plant in the Philippines had a flooded meter pit and the coil housing was cracked. The transmitter was fine. The buyer needed a DN200 hard rubber liner spool with 316L electrodes. We shipped a compatible induction spool in 12 days. The site avoided a full meter swap and saved about 40 percent on cost.
What an Induction Spool Does in a Magnetic Flow Meter
An induction spool is the welded measuring tube with field coils, electrodes, and liner. In Krohne and Altometer style magnetic flow meters the spool creates the magnetic field. The electrodes pick up the voltage signal. The transmitter converts that signal to flow rate. If the liner is worn or the coils are wet, the reading drifts. You do not always need a new transmitter.
In practice most engineers skip this part. They order a complete flow tube when the liner fails. But if the transmitter is less than five years old, sourcing only the induction spool is cheaper. You need to confirm coil resistance, electrode type, liner material, process connection, and DN size before ordering.
Common Specifications for Procurement
We stock and source inline electromagnetic flow meters from DN15 to DN600. Standard liner options include hard rubber, PTFE, PFA, and EPDM. Electrode materials include 316L, Hastelloy C, titanium, and tantalum. Process connections cover wafer, flanged EN 1092-1, ANSI 150, ANSI 300, JIS 10K, and DIN PN16. Output options include 4-20 mA HART, pulse, RS485 Modbus, and Profibus DP. ATEX Zone 1 approval is available for hazardous area lines.
For Krohne industrial process induction spools the key data is written on the meter nameplate. Send us the serial number, DN size, liner code, electrode code, and flange rating. A clear photo of the nameplate is enough in most cases. If the nameplate is gone, measure the pipe ID, flange bolt circle, and liner thickness. We can reverse engineer the spool from those values. Minimum fluid conductivity for standard magnetic flow meters is 5 µS/cm. PTFE lined spools handle process temperatures from -25 °C to 150 °C. A PT100 sensor can be added to the transmitter if the site also needs temperature data.
Industries Where We See Repe
at Orders

Water and wastewater plants order DN80 to DN400 meters for raw water, backwash lines, sludge, and chemical dosing. A desalination plant in Saudi Arabia needed a seawater flow meter replacement for a Krohne unit. We supplied a DN150 PTFE lined meter with titanium electrodes and 4-20 mA HART. The order shipped to Dammam in 10 days.
Food and beverage buyers often need PTFE or PFA liners for CIP cleaning. A dairy in New Zealand replaced an Altometer style meter on a milk pasteurizer line. We quoted a DN40 sanitary connection flow meter with 316L electrodes and IP67 housing. The line ran 24 hours after install.
Chemical and marine customers ask for aggressive media compatibility. Sulfuric acid, caustic soda, seawater, and urea all need different liner and electrode combinations. Tell us the concentration and temperature. We will match the wetted parts to the process. Flow range can be stated in m3/h or kg/h depending on the fluid. No need to guess.
Quotation Data You Need to Send
For a fast quote send six data points. Pipe size in DN or inches. Liner material if known. Electrode material if specified. Process pressure in bar. Process temperature in degrees C. Flow range in m3/h or kg/h. Also mention the country and port of delivery. We ship by DHL, FedEx, air freight, or sea freight depending on size and urgency.
Because freight cost changes with flange size, a DN300 spool costs more to ship than the part itself in some cases. We quote ex works, FOB Shanghai, CIF, and DDP options. You choose the Incoterm that fits your import license and tax setup.
FAQ
Q: Can Silver Automation Instruments supply original Krohne induction spools?
We can source original Krohne parts through our procurement network. Lead time is usually shorter than local OEM channels in Southeast Asia and the Middle East. We also supply compatible induction spools when the original part is obsolete or over budget.
Q: How do I know if my Altometer flow meter needs a new spool or a full meter?
Check the signal. If the transmitter powers up and self test passes but flow shows zero or drifts, the spool liner or electrodes are often damaged. If the transmitter is dead, a complete meter is usually the better choice.
Q: What is the typical delivery time for a Krohne style induction spool?
Standard DN25 to DN200 spools with hard rubber or PTFE liners ship in 7 to 15 days. Large DN250 to DN600 spools or Hastelloy and tantalum electrodes take 3 to 4 weeks. Custom flange ratings may add one week.
Q: Can you match the existing transmitter wiring?
Yes. We confirm coil resistance, electrode wiring, and excitation voltage before shipping. Most Altometer and Krohne compatible transmitters accept the same 4-20 mA HART wiring. If you need a new transmitter we supply that as well.
Q: Do you ship to our country?
We ship to Southeast Asia, Oceania, Latin America, Africa, and the Middle East. Send your city and port. We will confirm freight cost and transit time with the quote.
