Coriolis Flow Meter Calibration - Smart Measurement

WebCoriolis flow meters deliver the highest level of accuracy in the industry. They can be used to verify the accuracy of other flow meters and are typically used in test benches for flow meter manufacturing. Coriolis flow meter accuracy is better for liquids than gas. Typical liquid accuracy is 0.1% and typical gas accuracy is 0.5%. WebIn comparison, flow meters with no moving parts offer the following accuracies: 0.1% to 0.5% for Coriolis flow meters, 0.2% to 2% for magnetic flow meters, and 0.7% to 1% for ultrasonic flow meters. ... Rotameters are usually limited to a 10:1 turndown ratio, which means they cannot accommodate a wide variation in flow rates. helle jansenWebJun 1, 2015 · Coriolis meters offer the advantage of a large turndown ratio—more than twice the turndown of a turbine meter. Flow velocity through a Coriolis meter is generally high. Velocity should always be considered when sizing a meter for an erosive fluid with high solids content and when considering piping limitations including pressure drop. helle ja helle

Coriolis mass flow meters use the Coriolis effect to measure the amount of mass moving through an element. WebBecause of their very precise accuracy, the Coriolis flow meters have a turndown ratio of about 100:1 or more. This means that if a meter is rated for a maximum flow rate of 200 gallons (757 liters) per minute, it is still accurate down to 2 gallons (7.57 liters) per minute. Typical mechanical meters have a turndown ratio of 10:1.
