The E-Flow uses highly accurate and reliable radar planar microwave technology to capture the true velocity and depth of flow zero contact with the flow. With the simple software to configure your E-Flow you can record and measure flow in any channel shape, whilst sending measure flow, level, and velocity seamlessly over the 4G network to view in realtime on the cloud platform. -
Page 4: Principle Depth Of Flow Measurement
1.2.3 Flow Measurement Principle The velocity and level measurements recorded by the E-Flow sensor is used to calculate the flow rate. Flow rate (also known as Q, as the flow, or as throughput) is the amount of fluid moving through a channel or pipe in a period of time. -
