1.1 Introduction
The DeLaval milk meter MM300 (A) is an
electronicmilk meter designed to record the
milk yieldof cows; see Fig. 1.
It has no moving parts.
Electrodes for conductivity sensing are
positionedin the regulator sensor valve.
The cable between the milk meterand the
sensor is permanently sealed.
A fat sampler can be connected to the
meter, tocontinuously collect a proportional
amount ofmilk. The sample is included in
the measuredyield.
The MM300 is certified by ICAR for official
milk recording.

1.2 Principle
The MM300 comprises of an electric circuit
board and a short transparent pipe, which
enablesfree passage for the milk.
The optical sensors detect slices of milk
flowingthrough the channel. A high speed
processor inthe milk meter processes
100,000 measurementsper second.

These measurements are analyzed in order
toseparate milk slices. The following data is
calculatedfor each milk slice:
Length of milk slice
Speed
Acceleration
Air entry
Density
By analysing and computing the above
data,accurate milk flow and yield is
achieved.
