Fischer & Porter Flow Meter Catalog: Legacy Rotameters and Magnetic Flowmeter Parts
Quick Answer: If you are searching the Fischer & Porter Flow Meter Catalog for legacy rotameters and magnetic flowmeter parts, you do not need the original PDF. Silver Automation Instruments cross references legacy Fischer & Porter data and supplies compatible tubes, floats, electrodes, liners, and transmitters. Send your tag number, pipe size, and flow range for a quote.
Why Legacy Fischer & Porter Flow Meters Still Matter
Many plants in Southeast Asia, the Middle East, and Latin America still run Fischer & Porter rotameters and magnetic flowmeters installed 20 or 30 years ago. The original catalog is often lost. Maintenance teams still have the tag plate, and they still need parts. That is where we help.
Fischer & Porter is no longer an active brand. The original catalogs are hard to find. In practice, most engineers skip the catalog search and go straight to a supplier that can read the old model code.
What the Fischer & Porter Catalog Covered
The legacy catalog grouped small variable area meters under a 10A series and magnetic flowmeters under a 10D series. A 10A rotameter might have a glass metering tube, a stainless float, and a threaded or flanged connection from DN15 to DN80. A 10D magnetic flowmeter might have a PTFE or hard rubber liner and electrodes in Hastelloy C or 316L stainless steel.
We work with these series codes often. A customer in Vietnam recently sent us a photo of a 10D tag with a missing transmitter board. We matched the liner and electrode data to a modern Silver Instruments magnetic flowmeter and a HART transmitter.
Legacy Rotameter Parts We Supply
We supply replacement glass tubes, metering floats, needle valves, O-rings, and scale plates for Fischer & Porter style rotameters. The common sizes are DN15, DN25, DN50, and DN80. Process connections can be female threaded, male threaded, or flanged. Flow ranges are always part of the quote because the float shape must match the scale.
Tell us the model code from the tag. If the tag is gone, measure the tube length and the process connection. We can often identify the meter from those two numbers plus the flow range.
Typical applications include nitrogen purge lines, chemical dosing skids, and boiler feedwater sampling. We have supplied rotameter parts for a paint manufacturer in Southeast Asia and a water treatment plant in the Philippines.
Magnetic Flowmeter Parts for Older Fischer & Porter Units
For 10D series magnetic flowmeters, we supply liners, electrodes, grounding rings, and replacement transmitters. Common liner materials are PTFE, PFA, and hard rubber. Electrode materials include 316L stainless, Hastelloy C, and tantalum.
Many old F&P magmeters used a separate converter. You can replace that converter with a Silver Instruments transmitter with 4-20 mA HART, pulse output, and Modbus RTU. We have done this on desalination plants in Oman and wastewater plants in Chile.
Here is the thing.

Replacement Instead of Repair
Sometimes a legacy rotameter or magmeter costs more to repair than replace. If the meter body is cracked or the liner is worn past the electrode tip, a new Silver Instruments meter is the better option. We offer metal tube rotameters, electromagnetic flowmeters, and ultrasonic flowmeters for DN15 to DN600.
So if your Fischer & Porter unit is beyond repair, we can cross reference the process data and propose a new meter. The new meter does not need to match the old footprint exactly. We often supply adapters or new flanges to fit the existing pipe.
How to Read a Legacy Fischer & Porter Tag Plate
Most engineers skip this part, but it saves time. Take a clear photo of the tag plate and the flow direction arrow. Note the model code, serial number, pipe size, liner material, and electrode material if visible. Also note the power supply and output signal.
If the tag is faded, use a flashlight at a low angle. The code is often engraved. A typical tag might read 10A2235 for a rotameter or 10D1430 for a magnetic flowmeter. Send the photo to us through WhatsApp at +86 15365082610 or by email. We will identify the series and quote the right part.
FAQ: Fischer & Porter Flow Meter Parts
Q: Can you supply a Fischer and Porter rotameter tube only?
Yes. We can supply replacement glass tubes and matching floats for most 10A series rotameters. Send us the tube length, end fitting type, and the old float material.
Q: Do you have original Fischer Porter catalogs in PDF?
We do not keep original PDF catalogs for download. We use old catalog data and tag plate codes to cross reference parts. A photo of your tag plate is usually enough.
Q: What magnetic flowmeter parts are available for old 10D series units?
We supply PTFE and PFA liners, 316L stainless and Hastelloy C electrodes, grounding rings, and replacement transmitters with 4-20 mA HART or Modbus RTU.
Q: How do I confirm my legacy F&P meter size from the tag?
Look for a two digit number like 15, 25, 50, or 80 on the tag. That often shows the meter size in millimeters. If the tag is unreadable, measure the process connection and send us the flow range.
Q: Can Silver Instruments replace a Fischer Porter flowmeter with a new model?
Yes. We can cross reference your old tag data and propose a new rotameter or magnetic flowmeter. We match pipe size, liner, electrode, flow range, and output signal.
