ABSTRACT:
A vortex swirl flowmeter sensor circuit electrically connected to an electro-thermal sensor generates a voltage signal output from a flowmeter probe with the signal having a large signal to noise ratio. The sensor is electrically connected in a bridge network in the input to an operational amplifier. The output of the amplifier is fed back through a signal enhancement circuit for maintaining the instantaneous temperature of the sensor, and therefore its resistance constant.
