MantaRay

• Measures flow in partially filled pipes and open channels
• No flume or weir required
• 4-20mA and Relay outputs for connection to Samplers and SCADA
• Powered with built-in rechargeable NiMH batteries
• 2 million point data logger with USB output to Flash drives
• Backlit LCD display for flow rate, totalizer and menu system
  
• Simple 5-key Calibration
• Measures Reverse Flow
• Works in Irregular Channel Shapes

Designed for flow surveys in open channels, partially full sewer pipes and surcharged pipes. MantaRay is ideal for stormwater, sewage, irrigation water and natural streams. The MantaRay uses a submerged ultrasonic sensor to
continuously measure both Velocity and Level in the channel. The sensor resists fouling, corrosion and abrasion.
View realtime flowrate and total flow on the large backlit LCD display. Connect to samplers or SCADA and telemetry systems with the 4-20mA and relay outputs. Download flow log files to a USB memory stick. 

The MantaRay uses a submerged ultrasonic sensor to continuously measure flow or reverse flow. The sensor is a completely sealed ultrasonic unit with no orifices or ports. It is hydrodynamically shaped and designed to shed deposits and stringers for reliable operation in sewage, stormwater and stream flow applications.
