Variable Area Flow Meter Applications
Tips: How do variable area flowmeters handle high or low temperature environments?
Variable area flowmeters have standard and special high temperature models, the standard model is suitable for the medium temperature range of -20°C to 120°C, while the special model can work normally under the environment as high as 450°C or as low as -80°C. Users should choose the appropriate temperature range according to the actual working conditions and pay attention to the impact of high or low temperature environment on the accuracy of the stainless steel flow meter. In addition, the flowmeter housing and components are made of high-quality stainless steel to ensure long-term stable operation even under extreme conditions.
