GF Signet 3350

Full-Feature Transit-Time Ultrasonic Flow Meter System at an Affordable Price

Ultrasonic Flow Meters GF Signet 3350

The GF Signet 3350 is a state-of-the-art, economical alternative to magnetic, vortex and
differential pressure transmitters. Advanced microprocessing detection methods combine

with a versatile design to provide accurate and obstructionless ow measurement of

clean water applications. The GF Signet 3350 features high reliability and accuracy (up
to 0.5%), and long-term maintenance-free operation. Programming the GF Signet 3350
is simple via the front panel keypad; no PC is required for setup. The instrument features
a high-resolution, 2-line, backlit display and signal quality indication. The non-intrusive,

clamp-on sensors are quickly installed without interrupting process ows or incurring

pressure loss.

Features

• Flexible output options – Analog output,

totalizer pulse, relay outputs all included
as standard options

• Fast and easy installation – Simple,

menu-driven user interface enables quick
setup without need to connect to a laptop
PC

• Compact and lightweight –

Incorporates the latest LSI technology for
compact, rugged design. Meter weighs
less than 2 lbs

• Quick response – Ultra-fast transit-time

processing (200 ms) suits high-speed
batch processing measurements

• Multilingual – Instrument setup and

display supported in English, Spanish,
German, French and Japanese

• Superior temperature compensation –

Proprietary temperature and pressure
compensation system completely
eliminates error created by process

temperature and pressure uctuations
