Optrel float flowmeter for Supplied Air systems (4090.040)
The Optrel float flowmeter is a basic diagnostic tool designed to give you complete confidence that systems with a compressed air supply (Supplied Air) are working properly. Its job is a simple, quick and reliable check that the right amount of clean air is reaching the welder's helmet. In environments where the oxygen concentration is low or highly toxic contaminants are present, this check is not optional: it is a critical part of the safety procedure.

Technology details
Reliable air flow check
The float flowmeter, also known as a rotameter, works on a simple and reliable mechanical principle. Air from the system flows through a precisely calibrated tapered tube and lifts a small float inside it. The height to which the float rises is directly proportional to the volumetric air flow rate, so you can read the value in litres per minute immediately and unambiguously. With no electronics or complex mechanisms, there is nothing to fail, which makes it an ideal tool for routine daily equipment checks before entering a hazardous area. It is a key step in verifying that the respiratory protection system delivers the performance required by safety standards. Investing in this simple tool gives you certainty that the life-protecting system works to specification, which is absolutely critical for safety in low-oxygen or highly toxic environments.
