If the needle of the tester moves even slightly towards the zero side, it shows that electricity is flowing.* Conversely, if the needle does not move from ∞ at all, then there is no electrical conductivity. It can be judged that detection with an electromagnetic flow meter is not possil...
frequency are proportional to each other. Therefore, detecting the number or pulse of vortices makes it possible to measure flow. The main method of detection involves sensing the vortex vibration with a piezo element. However, a more robust method utilises ultrasonic waves to detect the vortex ...
with paddle wheel flow meters, the flow path is restricted in order to generate enough thrust to spin the paddles when there is small flow. For these types of flow meters, pressure loss occurs easily. Conversely, with electromagnetic, non-insertion thermal, and ultrasonic flow meters, there is...
