How to apply a level sensor in an unmanned smart restaurant?

- Dec 22, 2019-

An unmanned restaurant is a restaurant that does not require manual service. That is to say, in this restaurant, from the preparation of food to the platter and serving, etc., all are completed by smart robots. The restaurant guests only need to interact with the system in accordance with personal preference order.

Since there is no one involved, how do we control this amount when cooking food? Like we ourselves control the amount of water injection manually when cooking porridge and cooking, and also pass manually when selling drinks the volume of a cup with the naked eye. In many unmanned restaurants, the above problems are solved by various intelligent systems, such as a boiler that automatically injects water and porridge,. Businesses can easily control the total amount of food by installing two level switches provided by EPTSensor on the periphery of the boiler.

As shown in the photo, the positions of the highest and lowest liquid levels and the total rice required for porridge are determined in advance according to actual needs. Then, two level switches are installed in order. After starting the system, a certain amount of water will be automatically injected into the boiler. When the water level reaches the position where the high liquid level is located, the liquid level switch will send an alarm signal in the form of level after contacting the water, and then send it to the system control center to stop adding water. On the contrary, when the intelligent system starts to serve the porridge to the guests, the amount of food in the boiler has been decreasing. When the total amount has reached the point where the minimum liquid level is located, the level switch installed at that position will send a signal request to the total system to stop serving porridge. Generally speaking, the whole process of porridge cooking is controlled in real time by the system.

Finally, about liquid level sensor material, EPTSensor offers a total of two PC and PSU, because in this application involves the food industry, we recommend the use of PSU material, PSU material can withstand high temperatures, and it will not produce harmful subsdtances in high temperature environment that meet food standards and allow widespread use in the food industry. The specific model can choose FS-IR32D. This product is installed from the outside to the inside. Not only is the structure simple and easy to install, the power supply range is wide, the user has a large choice, and the low power consumption and low cost are also durable.


If it is not convenient to clean the appliance, it is best to choose a level switch installed from the inside to the outside, so that in actual use, only a small probe will be exposed in the tank without leaving any threads or wiring. It is more convenient to clean, and it is not easy to breed bacteria, such as model FS-IR1907


EPTSensor has produced this level switch for many years, and offers a variety of different series, including basic, digital, industrial and stainless steel glass, etc. Of course, it can also be customized according to customers' requirements.
