Abstract

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.

TECHNICAL FIELD Vehicle wash components and fluid management systems including such vehicle wash components are provided for use in locations where vehicles are washed. BACKGROUND Car washes are often labor, equipment maintenance, and input intensive. In addition, chemicals used in the car wash industry have become increasingly concentrated in order to reduce material handling concerns and shipping costs of those chemicals. SUMMARY According to certain implementations, a vehicle wash assembly for distribution of fluids at a vehicle wash location may include: a vehicle wash component operable to cause fluid to be dispensed from an outlet thereof into a fluid line for application onto a vehicle by a downstream applicator within the vehicle wash location. An inlet or the outlet of the vehicle wash component is associated with a port configured with an adjustable effective orifice area. A control system including at least one processor integrated into the vehicle wash assembly and communicatively coupled to the vehicle wash component may be configured to cause the vehicle wash component to operate to cause the fluid to be dispensed from the outlet. The control system receive instructions related to operation of vehicle wash component, the received instructions including at least one of timing information, a target flow rate or a target volume of the fluid to be dispensed from the outlet. In response to receipt of the instructions, the control system may be configured to analyze the instructions and generate separate instructions for operating the vehicle wash component based on the analysis. The separate instructions may differ from the received instructions and 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. The control system may transmit the separate instructions to cause the vehicle wash component to dispense the fluid according to the separate instructions during a dispensing operation. In various implementations and alternatives, the instructions related to operation of the vehicle wash component may include the target flow rate or the target volume, and the analysis of the instructions by the control system includes at least one of: determining the effective orifice area of the port to reach the target flow rate during the dispensing operation, or determining a duration of time for the dispensing operation of the vehicle wash component to reach the target volume. The control system generates the separate instructions for operating the vehicle wash component by generating the separate instructions to cause the vehicle wash component to operate according to at least one of selected operational parameters or for a selected duration of time to reach the target flow rate or the target volume, and upon the control system causing the vehicle wash component to operate according to the separate instructions. The control system may determine from one or more communicatively coupled flow meters an actual flow rate of the fluid dispensed from the vehicle wash assembly. The control system may then determine the actual flow rate does not correspond to one of the target flow rate or the target volume, and may generate modified separate instructions to cause the effective orifice area of the port to be adjusted to reach the target. In such cases, prior to causing the effective orifice area of the port to be adjusted, the control system may analyze received flow rate information from the one or more communicatively coupled flow meters during an evaluation period to calculate the actual flow rate. The evaluation period may include one or more of: evaluation over a predefined volume of fluid dispensed from the vehicle wash assembly, evaluation over a predefined number of the dispensing operations of the vehicle wash assembly, or evaluation over a predefined accumulation of time during which the vehicle wash assembly is actuated by the control system during the dispensing operations. In some cases, the received instructions may be related to operation of the vehicle wash assembly further includes a target outlet pressure for dispensing of the fluid from the downstream applicator, and the analysis of the instructions by the control system may involve: calculating a pressure drop between the vehicle wash assembly and the downstream applicator based on the target outlet pressure; calculating a target fluid outlet pressure of the vehicle wash assembly necessary to achieve the target outlet pressure, and the control
