Title:
WIRELESS PROPORTIONAL FLOW INDICATION FOR A TIRE INFLATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2013/119498
Kind Code:
A3
Abstract:
A flow indication system for a central tire inflation system is provided. The flow indication system provides a venturi in fluid communication with the conduit providing air to a tire. A pressure reading is taken at the inlet and throat of the venturi and the air flowing through the venturi is calculated based on the pressure differential. According to some embodiments, the pressure readings are provided to a microcontroller that uses a table and interpolation algorithms to calculate the flow of the air flowing through the venturi, such as the mass of air in a given unit of time (grams/second for example).
