gauge for water tank level
Generally, the water tank of a car does not have a water level gauge. The water filling pot of the water tank has a water level alarm light. As long as the water in the kettle is not less than the minimum level, the water tank will not be short of water. You'd better keep it at the highest mark. Or add a water level gauge. Generally, the water level gauge should be installed at the bottom of the lock water level, but it needs to be installed by hanging in the air. In this way, it is convenient to measure the depth of the water level and is not easy to cause errors.
The automobile water level sensor is used to measure the liquid level, and is used together with the water level gauge. 4~20mA, 0~5v, 0~10mA and other standard signal output modes can be selected by users according to their needs.
According to the nature of the deviation, it sends the "open" and "close" instructions to the electric water supply valve to ensure that the vessel reaches the set water level. After the water inlet program is completed, the computer in the temperature control part sends an "ON" command to the electric valve supplying heat medium, so the system starts to heat the water in the container. When the set temperature is reached. Only when the controller sends out the command to close the valve and cut off the heat source, the system enters the thermal insulation state.
If the liquid level cannot be detected, it cannot be found in time when there is a loss, which may lead to serious consequences. It is recommended to replace it in time. But I don't know what type of liquid level sensor you have, but I know that there is a kind of photoelectric water level sensor that can sense the change of water level and send a signal to remind you. When there is no water, the light emitted by the LED is reflected from the perspective mirror and sent back to the receiver. When the water level is relatively high and the liquid is immersed in the lens, the light is refracted in the liquid, which causes the receiver to receive little or no light. According to these two conditions, the sensor can judge whether there is liquid in the container, and then send out a signal for external alarm or control circuit.
