Variable Area Flowmeter Calibration

Variable Area Flow Meter Calibration Services (Rotameters)

Labcal provides specialist variable area flowmeter calibration for gas and air flow measurement across laboratories, manufacturing, utilities, and industrial process environments. Variable area flowmeters, also known as rotameters, are widely used for visual flow indication and basic control. Regular calibration helps maintain accuracy, traceability, and confidence in your readings.

We calibrate variable area flowmeters across a wide range of gas flow rates and gases including Oxygen, Helium, CO², Argon and Nitrogen, supporting routine maintenance and traceable calibration.
