1. A method of measuring of flow rate using a measured element rotating in response to flow and a handheld electronic device, the handheld electronic device comprising at least one of a smart phone, tablet or laptop and including a processor, the method comprising:
- identifying one or more properties associated with the measured element using the handheld electronic device;
measuring rotational speed of the measured element using the handheld electronic device, including recording a plurality of sequential images or a video of the measured element as it rotates using a camera of the handheld electronic device; and
calculating a flow rate using the one or more properties associated with the measured element and the rotational speed of the measured element using the processor of the handheld electronic device.

Abstract
The methods and systems described herein can be used for remote measuring of flow rate from a multitude of different flow meters without requiring each flow meter to be capable of onboard processing and displaying of flow rate information. A single electronic device can be used to remotely measure the flow rate of a multitude of different flow meters.
