fresh water rv tank level gauge
The existing RV water temperature gauge, water level gauge and voltmeter are generally set separately , and there is no alarm prompt of high voltage or low voltage . They can only display the water level of a group of liquid tanks. The circuit routing is complex . Most of the water level display accuracy is 40mm , and the display accuracy is not high enough . It needs an RV water temperature and level gauge with simple structure , integrated display voltage , water temperature and water , alarm prompt and capable of displaying the status of two groups of liquid tanks .
The touring / RV car water temperature and water level gauge comprises a main shell and a circuit board , the circuit board is fixed in the main shell through screws , the circuit board is externally connected with the touring car battery , the back of the circuit board is provided with MCU control chip , buzzer and relay, the front of the circuit board is provided with a display screen , the display screen includes voltage display screen, water quantity display screen and water temperature display screen , the front of the circuit board is also provided with function keys and indicator lights , the display screen The buzzer , relay and indicator light are all connected with the output end of MCU control chip , the function key is connected with the input end of MCU control chip , the display screen, function key and indicator light are clamped on the surface of main shell , and also includes sensor probe. The sensor probe is provided with water level sensor and temperature sensor , and the input end of MCU control chip is provided with double interfaces . The RV water temperature and water level gauge of the utility model integrates the display of voltage, water temperature and water , and has a temperature monitoring function while detecting the water level. The water temperature and water level of the two rented liquid tanks are displayed respectively through the function key switching display screen . When the battery voltage and water level are too high or too low , it will give an alarm through a buzzer and an indicator light , which has the function of anti freezing .
