Afimilk MPC Milk Meter Body
Afimilk MPC body is a measuring chamber connected as part of the milking system in the
parlor. The milk meter body is installed between the milking cluster and the milk line thus
all the milk harvested from the cow flows through the body during milking. The Afimilk
MPC body is an assembly of three main parts:
o Upper Cover and Inlet Port: Milk enters the main chamber through the inlet. The
inlet is available in two diameters: 5/8 inch, or 7/8 inch (see Ordering Afimilk MPC,
below).
o Mid-Section: Milk fills up the measuring chamber in the mid-section while the
outlet port's valve is closed. The mid-section body contains the following
components:
> Three electrodes measuring milk electrical conductivity
> A cylindrical valve, which also serves as overflow tube
> A silicon gasket
o Lower Cover and Outlet Port: Lower cover is the milk discharge mechanism of the
milk meter. Its outlet port connects the milk meter to the main milk line via a
rubber elbow pipe. The mid-section body contains a solenoid and diaphragm
lifting and lowering the valve in the mid-section, allowing milk to accumulate and
be dumped into the main milk line per Afimilk MPC's operation sequence.
The electrodes detect milk conductivity
and the milk level in the mid-section.
When a full mid-section is detected, a
signal is sent to energize the solenoid.
When the solenoid is energized, vacuum
causes the flexible diaphragm to pull the
valve down, a path opens between the
mid-section and the lower cover and the
milk drains via the outlet port into the
milk line.
Each portion of milk is measured
precisely. The amount of each portion
may vary from 200 to 330 cc, depending
on the milk flow rate.
