System, method, and network for controlling distribution of chemicals and fluids
A vehicle wash assembly for distribution of fluids at a vehicle wash location includes a vehicle wash component operable to dispense fluid into a fluid line for application onto a vehicle by a downstream applicator, and an inlet or outlet of the vehicle wash component is associated with a port configured with an adjustable effective orifice area. A control system receives instructions corresponding to timing information, a target flow rate and/or a target volume of the fluid to be dispensed from the outlet, analyzes the instructions, and generates separate instructions that differ from those received. The separate instructions include a time for when the vehicle wash component is to be actuated, a duration of operation upon actuation, and an effective orifice area of the port. Upon transmission, the separate instructions cause the vehicle wash component to dispense the fluid according to such instructions during a dispensing operation.
