The DigitalFlow GM868 flowmeter uses the patented Correlation
Transit-Time™ method of ultrasonic flow measurement to
provide accurate, drift-free measurements, without impeding or
obstructing the flowt.

Wide range of pipe sizes and flow conditions
With its broad range of measurement velocities, and its
ability to measure flow in any pipe from small to very
large, one DigitalFlow GM868 meter does the job of several
conventional meters. It handles pipes from 1 to 120 inches in
diameter (2.5 cm to 3 m), and velocities from 0.1 to 150 ft/s
(0.03 to 46 m/s)—in either direction, in steady or pulsating
flow.

For maximum accuracy, use a two-channel meter to
measure along two different paths at the same location.
A two-channel meter can also measure the flow in two
separate pipes or at two different places in the same pipe.

No pressure drop, low maintenance
Since the DigitalFlow GM868’s transducers do not obstruct
the flow, they generally do not cause any pressure drop as
other types of flowmeters do. The DigitalFlow GM868 has no
parts that foul or collect debris, and no moving parts to wear
out. As a result, it requires no lubrication, cleaning or other
routine maintenance.

Digital and analog output options
The DigitalFlow GM868 flowmeter makes it easy to send
the data where it needs to go, through the standard digital
output, standard or optional analog outputs or optional
alarms. All outputs are conveniently set up and calibrated
from the keypad or from a computer using the PanaViewPlus
program.
