The accuracy of ultrasonic flow meters is influenced by changes in liquid temperature and sound speed. Variations in liquid temperature lead to changes in sound speed, which impacts the flow calculation accuracy. Changes in chemical composition, pressure, and reaction products can alter sound speed, thus influencing measurement precision. This article provides sound speed data for various liquids to enhance the precision of ultrasonic flow meters.
1. Fluids exhibit different sound speeds at various temperatures
Ultrasonic flow meters primarily calculate flow based on the sound speed of the liquid. Liquid sound speed is influenced by temperature and chemical concentration, affecting the flow measurement. Additionally, the state of the fluid, such as temperature and pressure, can affect measurement accuracy.
2. The environment is the main factor affecting liquid sound speed
Liquid sound speed changes due to environmental factors. Chemical reactions, composition changes, sedimentation, and environmental pressure all affect sound speed. The production of by-products alters the liquid concentration and impacts sound speed, making it a constantly changing parameter. Sound speed data serves as a reference, not a fixed measure.
