Abstract

An apparatus, method and system providing for calibration and/or control of a liquid dispensing system is disclosed. The hand-held calibration auditing tool includes a flow meter ( 36 - 37 ) with inlets adapted for quick connection to one or more liquid inputs to a liquid dispensing system ( 10 ). A sensor ( 94 - 95 ) having a data output of liquid flow information for a liquid input to the dispensing system ( 10 ) is operably connected to a controller ( 12 ) to receive the liquid flow information for the liquid input. The controller ( 12 ) provides a dilution rate and other liquid flow information for a liquid product input to a dispenser.

First claim

What is claimed is:

1. A liquid dispensing system, comprising:
a dispenser in fluid communication with a plurality of liquid inputs, said plurality of liquid inputs comprising a plurality of liquid products and at least one liquid diluent;
a plurality of flow meters, wherein each fluid communication between the dispenser and a liquid input includes one of the plurality of flow meters, and wherein each flow meter outputs data of liquid flow information related to the fluid communication between the dispenser and liquid input; and
a controller operably connected to the plurality of flow meters to receive the outputted data of the liquid flow information for each of the plurality of liquid inputs, wherein the controller displays a dilution ratio comprising an amount of liquid product communicated to the dispenser relative to an amount of liquid diluent communicated to the dispenser.

2. The dispensing system of claim 1 wherein the controller comprises a data store for storing the liquid flow information for each of the plurality of liquid inputs.

3. The dispensing system of claim 2 wherein the data store includes date time stamp information associated with the liquid flow information.

4. The dispensing system of claim 1 wherein the controller further comprises a data link configured to transmit the liquid flow information and dilution ratio.

5. The dispensing system of claim 1 wherein the dispenser further comprises a liquid output for dispensing a use solution to a end-use application.

6. The dispensing system of claim 5 wherein the end-use application comprises at least one of:
a. an on-site formulator;
b. a laundry system;
c. a warewashing system.

7. The dispensing system of claim 1 wherein each of the plurality of flow meters is positioned within the system prior to combining the liquid product and the liquid diluent.

8. The dispensing system of claim 1 wherein at least one of the plurality of flow meters includes means for dampening in-line pressure pulses.

9. The dispensing system of claim 8 wherein the flow meter associated with one of the plurality of liquid inputs is in fluid communication to a liquid diluent configured to measure higher volume flow than the flow meter associated with one of the plurality of liquid inputs in fluid communication to a liquid product.

10. The dispensing system of claim 8 wherein each of the plurality of flow meters is connected in fluid communication to a separate one of the plurality of liquid inputs.
