Dairy Cheq® MilkGuard & FD

“We were alerted early and able to fix the problem and prevent high bacteria counts.  All in all I sometimes wonder how we managed without this valuable management tool.  I am and continue to be impressed.”

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
