Wave probes operate by measuring the current that flows between two stainless steel wires that are immersed in water. This current is converted to an output voltage that is directly proportional to the immersed depth.
Each wave probe comprises two parallel stainless steel rods with a plastic head and foot. The head is fixed to the calibration stem and a mounting block is supplied that allows the calibration stem to be fixed to any vertical surface.
The water level float gauge uses a float which moves up and down a displacement transducer to measure slowly changing water levels, typically in flumes or 3D basins. The water level is determined by accurately measuring the distance from the head of the transducer to the magnetic field produced by a magnet mounted inside the float. The advantage of this method is that there is no contact, and therefore no friction, between the float and the transducer.
The transducer consists of a 10mm diameter stainless steel tube, which contains a stretched magnetostrictive wire. The tube is welded to a stainless steel head which contains all the electronics for the transducer.
