20130134184 | LIQUID METERING AND INJECTION SYSTEM - A liquid metering system for a commercial or industrial laundry operation includes a dosing tank supported by a weight sensor that can measure the weight of cleaning solution transferred into the dosing tank. A valve assembly is operable to transfer the measured cleaning solution from the dosing tank to a transport tank, and a discharge pump is operable to pump the measured cleaning solution from the transport tank to downstream equipment. Measured quantities of different cleaning solutions can also be mixed in the transport tank before being delivered to downstream equipment. A control system regulates operation of the various pumps, valves, and manifolds, and monitors the readings from the weight sensor. | 05-30-2013 |
