The present invention provides an improved sensor which is able to reject noise produced by the passage of water over the sensor. This includes providing an enlarged guard plate close to the surface of over which the water passes, reducing the total amount of water passing over the sensor and providing a drip guard plate to introduce a correcting voltage signal into water which passes over the sensor.
