<p>A gas turbine meter (1) that is miniaturized based on its design is disclosed. While the size of the gas turbine meter (1) is small, it has a large rangeability over a very large range of pressure. The turbine meter includes a body (10) which is bilateral or symmetrical. Diffusers (15) are included with the turbine meter (1) that maintain the rotor (45) of the turbine meter (1) in position and prevent dust from entering into bearings (75). The rotor (15) of the turbine meter (1) optimally has twelve flat blades (150), each having an angle of 45° from the plane of the blank (12). Close clearance is maintained between the blades (150) and the interior (11) of the meter. Notches (140) are formed at the lower end of the blades (150), thereby forming the shafts (170) of the blades (150) which are optimally sized to increase stiffness. The magnetic strength of the magnetic pick-up (400) has a small genus strength to avoid magnetic drag.</p> |
