About the Oil Flow Meter

The oil flow meter prototype has been developed for 'real time' oil flow measurement with specific attention given to the mechanical packaging to allow dyno and 'on car' correlation of data in motorsport applications.

The oil flow meter installs directly into a suitable existing oil pipeline modified to accept flexible -16 tube connector couplings.

Using the established ultrasonic 'time of flight' measurement principle, the oil flow meter is a true solid-state device. The flow tube, transducers and mounting arrangement are compatible with an installation on an engine, capable of measuring liquid flow of up to 200 litres/min and temperatures of up to 150°C.

The remote processing electronics are rated for 105°C and can be placed up to one metre away from the flow tube. These electronics provide the user with flow data over a USB or analogue interface and can be powered from an automotive supply of 5 to 24 volts.

The ultrasonic oil flow meter is currently in prototype form, with the final product under development.
