This micro flow sensor has been initially developped to measure the flow through a micro dispensing valve. Micro dispensing valves usually use pressurized fluid from a reservoir and they are activated by an electromagnetic coil. Because micro valves have very short opening times of only a few milliseconds, the flow sensor needs to have a very short reaction time and high sampling rate of 20 kHz, to be able to capture this event properly.

Because the Pulsed Flow Sensor is capable of measuring strong fluctuating flow, it can be used to monitor the flow of pulsating pumps. For pump manufacturers the pulseform can be measured to optimize the pumping performance of their product. In other applications the volume flow of the pump just has to be measured to control the process.
The Pulsed Flow Sensor was designed to measure volume flows that take microseconds to minutes. It can automatically Integrate the volume flow to determine the processed volume from a dispensing or sampling process.
