Greyline AVFM 6.1 Area Velocity Flow Meter
Part:
AVFM 6.1
Measure flow in open channels and partially filled pipes without requiring a flume or weir.
No flume or weir required
Programmable for custom channel shapes, pipe sizes
Submerged ultrasonic sensor measures flow, velocity and level
Large backlit LCD display
Onboard 26 million point data logger
Multiple signal outputsGreyline AVFM 6.1 Area Velocity Flow Meter
Measure flow through open channels, partially full pipes and surcharged pipes without a flume or weir. Ideal for wastewater stormwater, effluent, industrial wastewater, and irrigation water.

The AVFM 6.1 uses a submerged ultrasonic sensor to continuously measure both Velocity and Level in the channel. The sensor resists fouling, corrosion and abrasion. The flow meter can be configured with the standard submerged velocity-level sensor, or with submerged velocity plus a separate non-contacting ultrasonic level sensor, for highly aerated fluids or those with high concentration of suspended solids.

View flow rate and total flow on the large backlit LCD display and connect to external devices with three 4-20mA outputs and two control relays. Flow rate, volume, run hours, and diagnostic information available through the optional Modbus® RTU serial communications.

Easy to Install and Use
The AVFM 6.1 Area-Velocity Flow Meter measures both Level and Velocity to calculate flow in an open channel or pipe. Configuration is simple: enter the pipe diameter or channel dimensions and the AVFM 6.1 automatically computes and displays flow volume.

The ultrasonic sensor mounts inside the pipe or on the bottom of a channel with a stainless steel mounting bracket (included) and a single screw into the bottom of the pipe or channel. No special compounds, tools or hardware are required. The sensor is completely sealed with no orifices or ports.
