Construction/Design Principles:
|
|
The turbine meter is a volumetric measurement device which operates by sensing the linear velocity of the fluid passing through it. Using a known cross-sectional area of the meter housing enables it to determine the volumetric flow rate. As fluid passes through the meter, it conveys an angular velocity (RPM) to the rotor, which is proportional to the linear velocity of the flowing fluid.
|
| Since
the linear velocity of the flowing fluid though a
given area is directly proportional to the
volumetric flow rate, it follows that the speed of
rotation of the rotor is directly proportional to
the volumetric rate. |

The design of
liquid turbine meter is relatively simple. It consists of a
cylindrical housing similar to a flanged pipeline spool
piece, a precision balanced free-running rotor and a pick-up
assembly positioned as close to the rotor as practical
without penetrating the housing wall. Fluid passing through
the meter causes the turbine to rotate. Small pieces
of ferrous metal embedded in some or all of the turbine
fins, pass through the the magnetic field generated by the
Pickoff Coil. This disturbance in the magnetic field
is interpreted by the flow computer as a pulse. Quantifying
the total number of pulses in a given time period allows the
meter to accurately interpret/measure the total volume of
flow through the meter. |

Typical Applications: |
|
In general, Liquid Turbine Meters are well suited for measurement of any low viscosity liquid (50
cP is the suggested max) which is chemically compatible with the materials of construction of the turbine meter. Available materials include
316SS,
Brass,
Aluminum,
PVDF,
PVC, and Epoxy Coated Carbon Steel. Consider using a liquid turbine meter in
applications where you're currently using a Variable Area (Rotameter) Flow Meter.
