The TransPort
®
Model PT878GC is a transit-time clamp-on gas
flowmeter which combines all the features of a full-size gas
flowmeter with the advantages of a portable instrument.
This section describes the TransPort features and general system,
and explains the theory of operation.
Overview
Depending on the selected application, the TransPort PT878GC
measures the flow of clean, dry gases in pipes from 4 to 24 in. in
diameter. The flowmeter provides one linear 0/4-20 mA analog
output of flow velocities or volumetric flow rate of these gases,
measuring velocities from ±1 to ±120 ft/sec (±0.3 to ±40 m/sec),
along with one selectable frequency or pulsed totalizer output.
Figure 1-1 illustrates the PT878GC in use on a typical pipe, along
with cases for the PT878GC and accessories.
