摘要: A liquid flow sensor includes a housing positioned in conduit and comprises contacting portion extending generally parallel to an axis of the conduit. An electromagnetic coil is within cooperates with pair electrodes exposed on generate signal relating rate. Liquid velocity profile enhancement provided increase accuracy rate sensing. In particular, plurality projections or transverse ridges may be defined for causing turbulence adjacent portion. The have cylindrical shape circular cross-section. Alternately, open upper defining channel. preferably arranged two bands opposite side edges Each band also include gap respective electrode. series define sawtooth cross-sectional shape. Method aspects invention are disclosed.
