The GF Signet 3350 Ultrasonic Flow Meter is a state-of-the-art, economical alternative to magnetic,
vortex, and differential pressure transmitters. The GF Signet 3350 Ultrasonic Flow Meter combines
advanced microprocessing detection methods with a versatile design to provide accurate and
obstructionless flow measurement of any clean water application.
The GF Signet 3350 Ultrasonic Flow Meter is for use with pipes made of carbon steel, stainless steel,
cast iron, copper, PVC, aluminum, FRP, PEEK, PVDF, PTFE, PFA, and other materials. The GF Signet
3350 Ultrasonic Flow Meter is not suitable for use with polypropylene pipes.
The GF Signet 3350 Ultrasonic Flow Meter features high reliability and accuracy (up to 0.5%), and
long-term maintenance-free operation.
Programming the GF Signet 3350 Ultrasonic Flow Meter is simple via the front panel keypad; no PC
is required for setup. Compact and lightweight, the GF Signet 3350 Ultrasonic Flow Meter incorporates
the latest LSI technology for compact and rugged design at less than 2 pounds.
In addition, the GF Signet 3350 Ultrasonic Flow Meter features a high-resolution, 2-line, backlit display,
and signal quality indication. The non-intrusive clamp-on sensors are quickly installed without
interrupting process flows or incurring pressure loss. The GF Signet 3350 Ultrasonic Flow Meter has a
proprietary temperature and pressure compensation system, which completely eliminates error created
by process temperature and pressure fluctuations.
Transit Time Ultrasonic Flow Meters – Technology Explained
Transit Time ultrasonic flow meters are well-suited for relatively clean fluids with low to moderate
aeration. These meters operate by comparing the time for an ultrasonic signal to travel with the flow
(downstream) against the time for an ultrasonic signal to travel against the flow (upstream). The
difference between these transit times is proportional to the flow, and the flow meter converts this
information to flow rate and total. With this technology, the transducers are mounted on the outside
of the pipe, providing tremendous advantages over more traditional and invasive flow measurement
instruments such as magmeters, vortex meters, and turbine flow meters. These benefits include no
system downtime for installation, no system contamination, no pressure drop, no moving parts, and
no risk of leaks. This product is virtually maintenance free.
