MANUFACTURER: EMCO

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.
