Abstract: An apparatus and a method for measuring fluid flow parameters. The apparatus can have a plurality of upstream sensors and a plurality of downstream sensors in communication with a computer. By comparing the sensor reading to an ambient condition, or a known fluid characteristic, the presence of fluid can be determined. The computer can utilize measured data from the sensors and known sensor placement to calculate volumetric flow rate and make determinations about equipment health.

Abstract: A computer implemented method and system for ordering food that creates a cloud-based central account. The method uses computer instructions to create and store a user account and restaurant accounts in the central account. A dynamic library of restaurant information is connected to the user account, the restaurant account and the central account. A menu ordering software application is accessed by a client device processor. Computer instructions create an order and a code indicating the order price and menu items, prompt the restaurant to create the menu items in the order, and tell the client device processor when the order is ready for pick up.
