A capacitive liquid level sensor is integrated with a drinking vessel or the like, and provides a sensory output signal having a characteristic that varies as a function of liquid level in the vessel. The vessel can have a hollow wall with conductive plates placed or affixed on a back surface of an inner wall panel of a hollow wall or protected by a handle. The plates form a capacitor for which liquid displacing air in the vessel provides at least part of the dielectric. A timing circuit is responsive to the capacitance of the plates, which changes when the liquid level displaces air from around or between the plates and changes the effective dielectric constant. The circuit can produce a preferably non-visual signal that varies over a range of liquid levels, or can change when the level passes a threshold level.

The invention relates to a method for manufacturing a composite light wall made from WPC material / rigid foam. The method comprises two procedures of the molding of the outer layer of a hollow wall member and the on-site filling of a core layer. After being mixed and plasticated, wood fiber material, polymer material, various accessory ingredients and additives are made into the granular WPC material by a screw extruder. After being added into the screw extruder, the granular material is made into the outer layer of the wall member. With the completion of processes of hand piece, vacuum cooling, shaping, traction and cutting, the outer layer of the hollow wall member is obtained. A froth placer is used for performing on-site rapid rigid aeration for polyurethane material that is filled into the outer layer of the wall member, thus making a composite light wall plate made from the WPC material / rigid foam. The method for manufacturing the composite light wall made from the WPC material / rigid foam avoids the problem that the core layer and the outer layer of the wall member can not be extruded simultaneously and the core layers with different densities can be filled and foamed according to the strength of the wall member and on-site requirements, thus ensuring the transverse compressive strength of the wall member. The method for manufacturing the composite light wall made from the WPC material / rigid foam is convenient and flexible and has wide application range.
