GENERAL INFORMATION
Meet the Seametrics jWAVE. Capture accurate and
reliable ow readings with your mobile device, with less
hassle and in less time—wherever you need a ow or
volume measurement.
No wires. No bulky electronics box to lug around. Your
ultrasonic ow meter hardware installs on the outside of
your pipe in a snap—and senses through the pipe wall.
Your mobile device displays readings and helps you set
up the hardware.
The jWAVE Flow Meter solution starts with the jWAVE App
(downloadable from the app stores) and works on both
iOS and Android devices.
The jWAVE Flow meter is a compact, strap-on transit
time ultrasonic transducer device. The jWAVE operates
by alternately transmitting and receiving a burst of
sound energy between two transducers. It then wirelessly
transmits ow measurements to your mobile device. Use

the portable data logger to conveniently record ow for
as long as 14 days or as little as one minute.
The jWAVE is highly portable. Just bring the rechargeable
clamp-on meter in its lightweight, weatherproof case,
along with a tablet or smartphone (iOS or Android).
Bluetooth connectivity replaces wires, and the jWAVE App
guides you through setup.
The convenient cam cleats let you mount the ow
meter on any pipe in seconds—no cumbersome clamps
required.
Bi-directional readings are transmitted to your mobile
device for display and your location’s settings are stored
in the jWAVE App, ready for reuse.
When you are done, simply release the cleats, then take
the compact meter on to your next location.
