Device for the Measurement of the height of a liquid by laser or LIDAR which is applied to the regulation of the level of a liquid in a swimming pool

摘要

Device for measuring liquid by laser or LIDAR reflecting on a float and allowing regulation of the height of the liquid in a swimming pool. The float is maintained in the line of sight of the laser or LIDAR thanks to a tube or a structure integral with them. The information provided by the laser or LIDAR is processed by a processor which, via relays, controls the swimming pool pump, the liquid supply valve, a drain valve or pump. This device advantageously replaces a conventional probe device used in particular for regulating the buffer tank of an infinity pool. It is simpler to implement (a tube to be fixed instead of probes to be fixed precisely), more reliable (no fouling of the probes) and more precise Figure for the summary: Fig. 1
