LIQUID METERING DEVICE AND PROCESS FOR DISPENSING A LIQUID CLEANING SOLUTION

摘要

A liquid metering system for a commercial or industrial laundry operation includes a dosing tank supported by a sensor that can measure the volume of the fluid passed there though with a magnetic field. The flowrate or volume can be used to determine the amount of a cleaning solution dispensed to a plurality of washing machines. A plurality of valves, as well as the sensor and pump, may be controlled by a controller which opens and closes the valves and operates the pump, to control the dispensing of various cleaning solutions to the washing machines.

主权项

1. A liquid metering device for dispensing a cleaning solution in a laundry operation, the device comprising:
a first supply tank containing a first cleaning solution; a pump configured to withdraw the first cleaning solution from the first supply tank and provide an output stream having a flowrate; a sensor in communication with the output stream and configured to utilize a magnetic field of the output stream to measure a volume of the output stream passing through the sensor; a controller in communication with the sensor and configured to adjust a flowrate of the first cleaning solution based upon the volume of the output stream that has passed though the sensor.
