The Crucial Role of Dielectric Constant in Radar Level Measurement

Level meter /

Radar level transmitters are widely used in various industrial applications, utilizing microwave-based distance measurements to assess the liquid level in tanks and containers. Among all the selection parameters, the dielectric constant (εr) of the medium is one of the most critical factors influencing radar performance. 1. What is Dielectric Constant and Why is it Important? […]

Effects of Scaling on the Measurement Parameters of Electromagnetic Flow Meters

Flow meter /

The working principle of electromagnetic flow meters is based on Faraday’s Law of Induction: when a conductive fluid flows through a magnetic field, it cuts through the magnetic flux lines, generating an induced electromotive force (EMF). The magnitude of this EMF is proportional to the flow velocity, which is then used to calculate the flow
