A recent study showed that cancer among Indians aged 30-69 is the fifth leading cause of death. It is noteworthy that in the next few decades, cancer deaths in Uttarakhand and Bihar, Jharkhand, UP, MPs, Rajasthan and Orissa will continue to rise.
Experts at the Tata Memorial Center (TMC) recommend ensuring that clean drinking water and a diet rich in fresh vegetables and fruits help control the incidence of this cancer. In a study published in the Global Oncology Journal based on a study of TMC scientists and researchers at King's College London, seven states have been found to have the greatest impact on this deadly disease over the next decade. According to the study, from 1990 to 2016, the number of cancer deaths in India has doubled.
How to ensure clean drinking water? The use of a water purifier with a photoelectric level sensor ensures the purity of drinking water. The main working principle of the water purifier is as follows:
The impurities in the water are filtered out by layer-by-layer filtration hardware. Any water purifier is nothing but the outer casing. The inner filter membrane is basically the same on the market: quartz sand layer - stainless steel filter Net - PPF cotton - ordinary activated carbon - coconut shell activated carbon - ceramic filter - winding filter - titanium core - folding filter - hollow fiber - nanofiltration - RO membrane.
However, there is still a problem with the use of a water purifier. If the water level control part of the water purifier uses a conventional float switch, it will easily cause secondary pollution. Because of the structural problems, the traditional float switch always has bacteria after a period of use. If the float switch is not cleaned for a long time, the water pollution will become more and more serious, which will also endanger the health of the user.
How to prevent this secondary pollution? The photoelectric liquid level sensor adopts the principle of optical refraction. It is the condition that the internal transmitter tube emits light, and then the different light conditions reflected back when the liquid is contacted and when the liquid is not connected to determine whether the sensor position is in a water or water state. This gives a signal prompt. The photoelectric liquid level sensor can achieve an accuracy of ±0.5mm, and it is maintenance-free and has high reliability. The sensor is simple in construction and the sensor can be cleaned while cleaning the tank, which also ensures that the drinking water is clean.
