Abstract
Apparatus and related methods for continually measuring and dispensing precise amounts of bulk chemical in a car wash application. A gravimetric dispensing assembly can include a load cell and a syringe dosing pump that is suspended below the load cell such that an entire mass of the syringe dosing pump is communicated to the load cell. In this manner, the load cell can measure the actual mass of chemical being dispensed from the syringe dosing pump on a continuous basis without solely relying on the rated volumetric capacity of the syringe dosing pump. The syringe dosing pump can be driven by a stepper motor that can be pulsed as directed by a controller so as to maintain, increase or decrease an amount of bulk chemical being dispensed from the syringe dosing pump.
