The MantaRay Portable Area-Velocity Flow Meter measures
both and Velocity to calculate flow in an open channel orLevel
pipe. Calibration is simple: enter the pipe diameter or channel
dimensions and the automatically computes andMantaRay

The ultrasonic sensor mounts inside the pipe or the bottom of a channelon
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 orifices or ports.no

Careful selection of sensor mounting location results in best performance and
maintenance-free operation. Avoid locations where sediment builds up.

Best possible accuracy will result when t is not andhe water highly turbulent

displays flowthe rate and total on its backlit LCD display.

Built-in 2-Million Point Data
Logger

Use MantaRaythe to store time and date-stamped flow values at 10 second to 60
minute intervals. Daily flow reports are automatically created where total, minimum,
maximum and average flow rates are displayed on the LCD display. Transfer log files
to any USB flash drive just by connecting to the logger's USB output. Windows
software is included to display log files in graph and table formats, change
measurement units and generate flow reports. Export data to graphic or text file
formats, or directly to Microsoft Excel.

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 24VDC batteries to extend the MantaRay’s operating time
indefinitely. Or connect the battery charger supplied with each flowmeter for
continuous operation or for long term 4-20mA output and relay operation. Maximum
power consumption is 2.7 Watts.
