nnnnshaft)
nnnnFor liquids only
nnnnTangential turbine flow meters continue to be the most common
nnnnway to measure flow electronically in a wide range of industries.
nnnnEnhancements to tangential turbine flow meter systems are
nnnnproducing a flow-sensing device that is smaller, easier to install,
nnnnand more accurate than ever before. Malema manufactures a
nnnnline of Tangential Turbine (also called Paddle Wheel) Flow meters
nnnnthat utilize sophisticated circuitry to foster signal conditioning.

nnnn0-RING SEAL
nnnnIllustrated is the M-10001
nnnnModel with 1/4" ports.
nnnnOperation
nnnnThe rotational velocity of the
nnnnrotary wheel varies linearly
nnnnwith the average velocity of
nnnnthe fluid flowing through the
nnnnflow meter. A square wave
nnnnpulse is generated by a Hall
nnnnEffect from magnets
nnnnembedded in the vanes of the
nnnnrotor wheel. Depending on
nnnnthe output version of the M-
nnnn10001, the pulse signal is
nnnnrelayed directly, converted to a 0-10 VDC (voltage) output or a
nnnn4-20 mA (current) output. The voltage and current models are
nnnnspan-adjustable over the flow range of the unit.
nnnnCustom Versions Available
