The calibration reference allows the controller to adjust the measurements for variations in sound velocity due to changes in temperature and humidity. The sensor controller performs the necessary calculations to determine the distance to the water surface. The sounding tube is mounted inside a 6-inch diameter PVC protective well which has a symmetrical 2-inch diameter double cone orifice. The protective well is more open to the local dynamics than the traditional stilling well and thus does not mechanically filter much of the wind waves and chop. In areas of high velocity tidal currents and high energy sea swell and waves, parallel plates are mounted below the orifice to reduce the pull down effects. A schematic diagram of the new system is presented below.
