Ultrasonic Flow Gauge: A device for Fluid Flow Rate Measurement Through a Narrow Tube

Onboard propellant gauging of spacecraft used as a gas flow meter and liquid flow meter

Propellant availability onboard is one of the main factors determining the spacecraft life. It is essential to gauge the propellant accurately for the estimation of spacecraft end-of-life (EOL) and to optimize the mission strategy. The project aimed for GEOSAT class spacecraft and interplanetary missions. The developed ultrasonic flow gauge can be integrated into the spacecraft for onboard propellant gauging. Can also be used as a gas and liquid flowmeter. Lightweight, low power consumption, analog as well as digital output ports, test points in the circuits, capable of measuring flow rate from 0.1 LPM to 6 LPM are the major salient features of this device.

Used in space and aviation industries.
