Icarus Flow Meter: Legacy Gas Rotameter Component Spares and Variable Area Calibration Updates
Spares and Calibration Support for Legacy Icarus Gas Rotameters
Quick Answer: Silver Automation Instruments supplies aftermarket component spares and variable area calibration updates for legacy Icarus gas rotameters. Common spares include glass metering tubes, floats, needle valves, seals, and scale plates. Send the Icarus serial number, gas type, pressure, temperature, pipe size, and flow range to get a spares and calibration quote.
Many plants still run Icarus variable area gas rotameters on purge lines, blanketing lines, analyzer sample loops, and pilot gas feeds. These meters are simple and reliable. Original spares are now difficult to find. A cracked tube or a worn needle valve can stop a process line for days.
We have seen this on customer sites many times. A gas utility in Indonesia ran an Icarus rotameter on a nitrogen purge panel for nine years. The float started sticking. The glass tube was dirty but intact. The real issue was a swollen O-ring and a worn inlet valve seat. They did not need a new meter. They needed three small parts and a cleaned scale.
A paint manufacturer in Southeast Asia sent us six Icarus rotameters from a gas blending skid. Four units needed new floats and two needed complete tube and seal kits. The replacement parts matched the original dimensions and the meters returned to service within one week.
Icarus Gas Rotameter Spare Parts We Supply
We keep replacement parts for common Icarus gas rotameter sizes. The usual range covers DN6 to DN50 connections with flow spans from a few L/h up to about 200 m³/h air equivalent. We can also source parts for larger units when the customer provides a clear photo of the meter tag.
Spare parts scope includes borosilicate glass metering tubes, stainless steel floats, Hastelloy C floats, PTFE seals, Viton and Kalrez O-rings, needle valve cartridges, inlet and outlet compression fittings, back plates, scale plates, and mounting hardware. The floats and tubes are checked dimensionally against the old part before shipping. This reduces the risk of a wrong taper angle or a float weight mismatch.
How Variable Area Calibration Updates Work
Calibration is not only about cleaning the meter. Gas density changes when the process gas, pressure, or temperature changes. A rotameter scale is valid only for the original gas and reference conditions. If a customer changes from air to nitrogen or from nitrogen to carbon dioxide, the same float height gives a different actual flow.
Here is the thing. If the original scale is still readable but the gas is different, we can calculate a correction. If the scale is faded or cracked, we can supply a new scale plate or a calibration sticker. We need the original tube code, float material, float height marks, and the new gas composition. Our calibration bench uses an air or nitrogen reference and corrects to the target gas based on density, float geometry, and operating pressure.
For example, a customer in Australia was using an Icarus rotameter on a methane line at 0.4 bar g. The meter scale had been made for air at 1 bar abs and 20 °C. At the same float height, the real methane flow was much lower than the scale reading. We supplied a revised scale for methane at 0.4 bar g and a new set of PTFE seals. The meter then read within the customer specified tolerance.
Common Failure Modes on Icarus Gas Rotameters
The most common failure is a cracked glass tube. This often happens when the meter is installed with pipe strain or when the float is dropped d

Data Needed for a Spare Parts or Calibration Quote
Most engineers skip this part, but the serial number alone is not enough for a reliable quote. We need five details. We need the gas type or gas mixture, the operating pressure in bar g, the operating temperature in °C, the connection size in DN, and the required flow range. A photo of the scale and the float helps a lot.
Send these details by WhatsApp at +86-25-52155837 or by WeChat at +86 15365082610. You can also call us at +86-25-68650347. We will return a spares list, calibration proposal, lead time, and courier cost to your location.
Replacement Options With 4-20 mA HART Output
If the meter body is cracked beyond repair, we can quote a direct replacement. Options include a new variable area flow meter with 4-20 mA HART output or a thermal mass flow meter for very low gas flow. We also supply Coriolis mass flow meters when the customer wants high accuracy and direct mass flow output.
Why Work With Silver Automation Instruments
Silver Automation Instruments serves customers in Southeast Asia, Oceania, Latin America, Africa, and the Middle East. Our core products include Coriolis mass flow meters, electromagnetic flow meters, ultrasonic flow meters, vortex flow meters, oval gear flow meters, thermal mass flow meters, pressure transmitters, and paperless recorders. This range helps us support a legacy Icarus rotameter with spare parts or replace it with a new instrument when the meter body is beyond repair.
FAQ
Q: What is included in an Icarus rotameter spares kit?
A: A standard kit includes a borosilicate glass tube, float, O-ring seal set, needle valve cartridge, and inlet and outlet fittings. We build custom kits based on your meter tag and process conditions.
Q: Can you recalibrate a legacy Icarus gas rotameter for a different gas?
A: Yes. We can correct the scale for air, nitrogen, oxygen, carbon dioxide, biomethane, natural gas, argon, and many process gas mixtures. The customer must provide the new gas composition and operating pressure and temperature.
Q: How do I know if my Icarus variable area meter needs recalibration?
A: The scale is faded, the float height does not match a reference flow meter, the gas type or pressure has changed, or the meter has been rebuilt with a new tube or float. Any of these conditions means the old scale is no longer reliable.
Q: What data do you need to quote spare parts?
A: We need the Icarus serial number, gas type, pressure in bar g, temperature in °C, pipe size in DN, and required flow range. A clear photo of the scale, tube, and float speeds up the process.
Q: Do you supply components for hazardous area installations?
A: We can supply spare parts for rotameters installed in safe areas and many hazardous area layouts. If the meter is part of an ATEX Zone 1 or Zone 2 panel, send the area classification and the original meter tag so we can verify material and fitting compatibility.
