Systems and methods for wash monitoring

A wash-quality monitoring system comprising:

• a housing;
• one or more processors housed within the housing;
• a supply water flow meter configured to be disposed in a supply water line of a wash system, the supply water flow meter being in communication with the one or more processors and configured to transmit, to the one or more processors, water flow readings of water flow through the supply water line;
• one or more chemical conduits disposed within the housing, the one or more chemical conduits each including a chemical input providing fluid communication into the housing and a chemical output providing fluid communication out of the housing;
• at least one color sensor disposed on each of the one or more chemical conduits, each of the at least one color sensor being in communication with the one or more processors and configured to transmit, to the one or more processors, color readings of a chemical disposed within each of the respective one or more chemical conduits;
• at least one chemical flow meter disposed on each of the one or more chemical conduits, each of the at least one chemical flow meter being in communication with the one or more processors and configured to transmit, to the one or more processors, chemical flow readings of chemical flow through each of the respective one or more chemical conduits;
• a current sensor in communication with the one or more processors, the current sensor being disposed on a power cable providing power to the wash system and transmitting, to the one or more processors, current readings of an electrical current flowing through the power cable;
• and
• a memory containing processor-executable instructions that, when executed by the one or more processors, cause the one or more processors to:
• determine that a new wash cycle has begun based on a determination that the current running through the power cable exceeds a predetermined idle value,
• compare the water flow readings with a predetermined acceptable range of water flow readings associated with the supply water line,
• in response to the determination that the new wash cycle has begun, compare the chemical flow readings with a predetermined acceptable range of chemical flow readings associated with each of the one or more chemical conduits and compare the color readings with a predetermined acceptable range of color readings associated with each of the one or more chemical conduits, and
• initiate an alarm if at least one of the water flow readings, the chemical flow readings, or the color readings are not within the respective predetermined acceptable ranges of readings.
