Abstract
A non-intrusive milk flow sensor includes first and second cylindrical nipples of a conductive material. Each of the first and second cylindrical nipples has an inner diameter. A molded rubber body has a passage therethrough joining the first and second nipples. The body fixes the first cylindrical nipple inline with the second cylindrical nipple and is bonded with the nipples. The body has an inner diameter defined by the passage equal to the inner diameter of the first and second cylindrical nipples. The molded rubber body insulates the first cylindrical nipple from the second cylindrical nipple. A first electrical lead is connected to the first cylindrical nipple. A second electrical lead is connected to the second cylindrical nipple.
