LED WATER LEVEL INDICATOR FOR A PRESSURE TANK TO ENABLE ACCURATE AND EASY RECOGNITION OF WATER LEVEL IN A DISTANCE OR THE NIGHT TIME

摘要

PURPOSE: An LED water level indicator for a pressure tank is provided to help water level management for a pressure tank by indicating the water level using a plurality of LEDs.;CONSTITUTION: An LED water level indicator for a pressure tank comprises a water level sensor, a control box(10), and an LED meter(20). The water level sensor is installed inside a pressure tank. The control box is installed on the exterior of the pressure tank, and comprises a control panel(11), a connector(12), and an SMPS(Switching Mode Power Supplies,13). The control box successively turns on LEDs of the LED meter electrically connected to the connector according to the water level of the pressure tank. The LED meter comprises an upper indicator unit in which a plurality of LEDs are serially installed and a first contact terminal and a first contact pin are formed on both ends, and a lower indicator unit in which a plurality of LEDs are serially installed and a second contact terminal and a second contact pin are formed on both ends. A plurality of LED meters are electrically connected so that the entire length is regulated according to the size of a pressure tank.;COPYRIGHT KIPO 2011
