Product definitions

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.

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.
