Features and Capabilities
The TransPort™ Model PT868 is a transit-time flowmeter which
combines all the features of a full-size flowmeter with the
advantages of a portable instrument.
This section describes the TransPort features and general system,
and explains the theory of operation.
Overview
The TransPort measures acoustically conductive single-phase
fluids, which may have a second phase present. This includes
most clean liquids, sewage, some slurries, some oil/water
mixtures, and liquids with a small percentage of entrained gas
bubbles. The flowmeter provides two linear (4-20 mA or 0-20
mA) analog outputs of flow velocities or volumetric flow rate of
these fluids, measuring velocities from ±0.03 to ± 12 m/s (±0.1 to
±40 ft/s).
The TransPort also provides two 4 to 20-mA analog inputs in
order to connect temperature transmitters to measure energy flow
rate of liquids. Energy flow rate may be calculated for water,
glycol, and water/glycol mixtures.
