Dairy Cheq® MilkGuard & FD

“The [Dairy Cheq® milk monitoring and reporting system] has helped us find numerous problems with our cleaning systems much quicker than we would have before… This system has been tremendously helpful to me because I can print off a graph or show them the data on the computer that proves that what I’m telling them is not working like it should be and it helps to better pinpoint exactly where the problem might be coming from.”

MilkGuard FD

How does it work?



Low temperature for pipeline cleaning

This alarm occurred following a pipe cleaning that was not hot enough. The pipeline wash had a maximum temperature of 39.2°C (103°F).  The target wash temperature of 40°C (104°F) for 4 minutes was not met, so the alarm occurred.

Possible Causes of the Low Temperature Pipecleaning Alarm may be:

  • Water heater is starting to fail
  • Pipe wash not started
  • Wash valves not in proper position
  • Pre cooler still running during the wash
  • Plugged screen in wash circulation loop
  • Not enough water volume to maintain temperature
  • Mixing valve adding cold water during hot cycle
  • Faulty check valve


Milk Too Warm

If the milk is not cooled within the required time (or regional requirement), then a “Regulatory” or rule-based condition has been breached.

The Dairy Cheq® MilkGuard FD will give the dairy farmer a warning 10 minutes after milking if cooling is not sufficient to meet the regulation.  If the milk is not cooled to below 5°C (Canada) or 45°F (US) quickly enough, then a “Regulatory” alarm will occur.

Possible Causes of the Slow Cooling Alarm may be:

  • Not enough cooling capacity
  • Failed compressor
  • Cooling efficiency is gradually degrading
  • Radiator needs to be cleaned
  • Leak in freon line
  • Thermostat has failed
  • Thermostat is not set to proper temperature


Switch on Cooler

If the milk cooling equipment is not turned on for the first milking, an alarm will occur.

The Dairy Cheq® MilkGuard FD looks for a temperature drop to detect cooling.

Possible Causes of the Switch on Cooler warning may be:

  • Forgot to switch on cooler
  • Failed compressor
  • Freon leak in cooling lines
