Ultrasonic flowmeters are widely used for flow measurement of gases and liquids. In particular, the Transmit-time Clamp-on Ultrasonic Flowmeters has its own characteristics. Several factors can influence its measurement accuracy.   1. Fluid Properties  - Viscosity: Highly viscous fluids can affect the propagation of ultrasonic waves and lead to inaccurate measurements. The more viscous the fluid, the greater the resistance to the wave propagation, which may cause deviations in the measured transit times and thus affect the accuracy of flow rate calculation. - Density: Changes in fluid density can also impact the measurement. Different densities can cause variations in the speed of sound within the fluid, which is crucial for the time difference measurement principle. If the density is not properly accounted for, it can result in errors in determining the flow rate. - Temperature: Temperature has a significant effect on the speed of sound in the fluid. As the temperature changes, the sp

In the field of flow measurement, choosing the right flowmeter is crucial for accurate and reliable results. In this blog post, we will compare three types of flowmeters - electromagnetic flowmeters, mass flowmeters, and ultrasonic flowmeters - specifically in terms of their advantages and disadvantages for measuring micro flows.   Electromagnetic Flowmeters Advantages:  - Accurate measurement of conductive liquids. - No moving parts, resulting in low maintenance. - Can handle a wide range of flow rates.  The working principle of an electromagnetic flowmeter is based on Faraday's law of electromagnetic induction. When a conductive liquid flows through a magnetic field, an electromotive force (EMF) is generated. The magnitude of this EMF is proportional to the velocity of the liquid. By measuring this EMF, the flow rate of the liquid can be determined.  Disadvantages:   - Only works with conductive fluids. - May be affected by electrical interference. - Can be relatively expensive.
