The MantaRay Portable Area-Velocity Flow Meter measures flow in open channels, partially filled and surcharged pipes using an ultrasonic sensor. It's designed for monitoring stormwater, sewage, industrial effluent, irrigation water and natural streams. The MantaRay displays and datalogs flow rate and total flow and connects to samplers, SCADA and telemetry systems.
Calibration is simple: enter the pipe diameter or channel dimensions and the MantaRay automatically computes and displays the flow rate and total on its backlit LCD display. Mount the sensor at the bottom of the pipe or channel and hang the IP67 electronics case above the high water level.
It's ideal for flow troubleshooting, balancing and checking performance of permanent flow meters. The new PDFM 5.1 is fast and easy to operate – you can mount the sensor on the outside of a pipe in less than a minute. Use the built-in keypad and calibration menu to set up the flowmeter for your application. The PDFM 5.1 works on any liquid containing bubbles or solids and is recommended for "difficult liquids" like wastewater, slurries, sludge, chemicals, viscous liquids and abrasives. Measures flow through most metal and plastic pipes including PVC, ductile iron, carbon steel and stainless steel.
|Flow range(Min-Max)||4-20 mA|
Monitor flow through open channels, partially full sewer pipes and surcharged pipes without a flume or weir. Ideal for stormwater, combined effluent, raw sewage, irrigation water and streams. Calibration is simple: enter the pipe diameter or channel shape and the AVFM 5.0 computes the flow volume and displays the flow rate. Measure forward and reverse flow and calibrate to channels of any shape.
How It Works
The AVFM 5.0 uses a submerged ultrasonic sensor to measure both Velocity and Level in the channel. The sensor is completely sealed with no orifices or ports. It mounts inside a pipe or at the bottom of a channel.
