Titan Enterprises has published a technical article discussing the factors which determine the overall performance of pulse output turbine flow meters and how each factor influences the accuracy of flow measurement.
Flowmeters have become essential measuring devices used in a vast array of different industries from commercial applications measuring the fuel feeding industrial boilers and flow monitoring of lubricant supply lines for wind turbines to dosing chemicals for agricultural sprays. Domestically, flow meters are installed to manage the dispensing of beer or coffee and built into washing machines and dishwashers to meter efficient water usage.
The repeatability and linearity of turbine flow meters are key elements in determining performance and overall accuracy. Both the mechanical properties of the flow meter and the physical properties of the fluid combine to influence the general performance of the flow measurement device.
The article explains terms synonymous with calibrating flow meters, such as the K-Factor, calibration uncertainty, repeatability, accuracy and linearity. It also discusses the relationship between flow factors and how they each influence overall meter performance.
Turbine flow meters, such as Titan’s Beverage flow meter and 800 series, offer the high level of repeatability and reliability required for accurate batch delivery systems, whilst the company’s Atrato and Metraflow ultrasonic flow sensors and the larger oval gear flow meters are highly accurate over wider flow ranges, especially with viscous liquids such as oils.
Neil Hannay, Senior R&D Engineer with Titan Enterprises, said: “When customers are deciding on appropriate flow meters to suit their application, they need to be aware of the difference between FSD linearity and ‘of reading’ linearity accuracy, as suppliers often do not specify which accuracy is being quoted for. The technical article from Titan illustrates how the linearity reading has a significant impact on the performance of the flowmeter, particularly at the low end of its flow range.”
