This electronic device increases the width of the pulses delivered by an AIC High Rate flowmeter and facilitates the connection of the flowmeter to a third party acquisition system which does not accept out narrow pulses.

The PULSE STRETCHER increases the standard 700 µs (0.7 ms) wide pulses delivered by an High Rate AIC sensor to 3000 µs (3 ms).

The box provides two output connectors, allowing simultaneous connection of an AIC fuel flowmeter to an AIC board computer and a third party acquistion system. The box streteches the consumption signal and provides an additional PNP consumption streteched signal output which can be used with third party acquisition systems when necessary.

The PULSE STRETCHER does not introduce any latency in the consumption signal.

The unit is housed in a robust aluminum case.

This device accepts the signal from any High Rate AIC fuel flowmeter and can be connected to any AIC data logger or AIC display and to a third party data acquisition system.

The box features a power indicator as well as a fuel pulse indicator. These indicators help is case of wiring issues.
