EMCO's
Turbo-Bar provides significant cost savings for line sizes from 3
to 80 inches without compromising performance. With high
accuracy, wide turndown, and a unique low- mass rotor design
without welded joints, EMCO's Turbo-Bar gives our customers the
benefit of over 30 years of practical experience. The
Turbo-Bar measures liquids or gases, including steam, for pipe
sizes from 3 to 80 inches.
EMCO has developed a unique
manufacturing process to fabricate a turbine rotor that offers
superior performance and maximizes longevity. Using an
electrical discharge process, the rotor assembly, including
the hub and the blades, is cut from one solid block of
stainless steel. No welding, which could have a negative
impact on the structural strength of the rotor, is
involved. In addition, the rotor assembly incorporates a
low-mass design, resulting in significant bearing load
reduction.
The Turbo-Bar measures the
point velocity of a fluid stream within the pipe. The
kinetic energy in the fluid stream causes the turbine rotor to
spin in direct proportion to flow. As each turbine blade
rotates past the magnetic pickup coil, the magnetic field is
broken and a small voltage pulse is generated.
The "Smart," microprocessor-based electronics
calculates the point velocity, using a linear relationship
developed during calibration, between the sensor input and
velocity. The electronics then translates the
local velocity into an average flow velocity and then into a
flow rate, based on user-selected engineering units. The
optional 8-character, 2-line, local display alternates between
flow rate and totalized flow. Either a square wave,
relay, or 4-20 mA output signal communicates to user
equipment.
