Greyline Instruments Stingray Operating Manual

Stingray Solution for Flow Monitoring

at Flume Site without Electrical Power

Newton Falls, NY

An operator visits the site periodically and downloads
the log file from the Stingray. The level data is used
with 'Greyline Logger' software to generate a flow
report for the Parshall flume.

The Stingray sensor was installed in the flume using
the stainless steel mounting bracket supplied with
each meter. A single screw is used to hold the
ultrasonic level-velocity sensor in place at the correct
position in the approach section of the flume. The
electronics enclosure is kept inside an unheated
shed beside the flume. The Stingray logger is rated
for operation from -20° to +60°C.

Stingray performance demonstration before

installation in a 36" Parshall Flume

Newton Falls Fine Paper needed to monitor
discharge of final treated effluent from their plant in
New York state. A 36" Parshall Flume was already
installed but no electrical power was available at the
flume location.

Plant engineers solved the problem with a Greyline
Stingray Portable Level-Velocity Logger. They
programmed the Stingray to take readings at two
minute intervals for operation up to six months on just
four standard D-cell Alkaline batteries.
