Abstract

PURPOSE: To provide a flow meter, which has no pulsation and which can operate calmly, by using as rotors a pair of helical gears of the same shape which are formed with continuously contacting tooth forms.
CONSTITUTION: A pair of rotos 1 and 2 are composed of mutually meshing helical gears of the same shape such that they can rotate about axes 3 and 4 within the casting of the body of a desired flow meter. If the front module, the height of the gears and the helix angle of thread are denoted as M, L and β, respectively, the paired helical gears are produced such that the helix percentage i which is expressed Ltan β/Mπ is given by i0- 0.5 (i0 stands for a positive integer). The capacity type flow meter using as the rotors the helical gears having continuously contacting tooth shape can perform calm operation without any pulsation thereby to provide a highly accurate flow meter.
