on sensors. Thanks to microprocessor-based electronics, the ow meter can be easily
congured from the front keyboard to particular applications. The Time Delta S is ideally
suited for liquid ow measurement for pipe diameters from 0.50 to 235 inches. Systems are
composed of a converter and sensor set. Applications include ow measurement of any
uid through which an ultrasonic signal may be transmitted, including those of unknown
sound velocities. The ow meter is a compact and lightweight instrument incorporating
the latest electronics and high speed digital signal processing technologies (32 bit MPU),
resulting in high performance and easy operation.
Features
• Dynamic flow correction – system
develops characteristic proles to correct
for optimal ow rates across the velocity
range
• Simple configuration – complete setup
from front keyboard and menu driven
software interface
• Digital outputs – 2 outputs may be
congured for totalizer pulse, ow switch,
range limiting, overow, memory alarm,
and abnormal signal condition
• Enhanced anti-bubble measurement
technology (ABM) – removes the effect of
entrapped and suspended ow bubbles
• Rugged and reliable – NEMA-6 (IP67)
enclosure makes Time Delta S well suited
to most industrial environments
• Maintenance free – no moving parts
provides long-term reliable operation
• High accuracy – ±0.5% to ±1.0% of
velocity typical on calibrated system
