| The STINGRAY Area-Velocity Flow
Meter includes a submerged ultrasonic sensor that is installed at
the bottom of an open pipe or channel. Powered by 4 Alkaline 'D'
cells, the unit is portable, rugged, waterproof and dust-proof.
Exposed materials are all plastic so the sensor resists fouling
and corrosion. It has no moving parts and no orifices, ports or
electrodes. The STINGRAY displays memory, battery, temperature,
velocity and level as selected via an integral LCD Bar Graph. It
has a built-in 130,000-point data logger with RS232 @ 28.8kb output
for fast data download. Windows compatible logging - interval and
period range - 10 sec (15days) to 20 min (4 years).
