Description

The MantaRay is a portable area velocity meter that measures flow using a submersible ultrasonic sensor. The unit is designed for flow surveys in open channels, partially-full sewer pipes, and surcharged pipes – making the portable open channel flow meter suitable for sewer monitoring, industrial flow monitoring, irrigation flow, and natural streams. Easy to Use The MantaRay Portable Area-Velocity Flow Meter measures both level and velocity to calculate flow in an open channel or pipe. 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. 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, making it resistant to build-up and fouling. Sleep Mode for Extended Battery Life Use the MantaRay’s ‘Sleep Mode’ function to extend battery life while logging flow. The digital display, outputs, and non-essential functions are suspended during sleep mode. Based on the logger interval, the MantaRay activates the sensor for 12 seconds to obtain flow readings and then resumes low power mode until the next logger sample interval. To indicate that sleep mode has been activated, the digital display flashes every few seconds while sleeping. External Battery Input Connect external 12 or 24 V DC batteries to extend the MantaRay’s operating time indefinitely.
