AVFM6.1 – Area Velocity Flow Meter
The Area Velocity Flow Measurement method is the most common method of all flow measurements. The AVFM 6.1 Area Velocity Flow Meter uses a submersible ultrasonic sensor measuring both the level and velocity of flowing liquid to calculate flow measurement in an open channel or pipe. The sensors are mounted either inside a pipe or at the bottom of a channel, and the sensor is built to resist fouling, corrosion, and abrasion. The AVFM 6.1 Area Velocity Flow Meter can be configured with the standard submerged velocity-level sensor or with submerged velocity in combination with a separate non-contacting ultrasonic level sensor, which is suitable for highly aerated fluids or those with a high concentration of suspended solids.
