1. Urgent need for translation! Cowherd help. Google takes a detour!
By controlling the airflow through the tower, the temperature of the cold water is controlled, that is, by alternately opening and closing the temperature sensor installed on the outlet pipe to control the engine of Tongqin, the constant temperature of the cold water is maintained.
2. Where is the water flow sensor of Haier JSQ20-H gas water heater located inside the machine?
The water flow sensor of Haier JSQ20-H gas water heater is located at the bottom of the machine and fixed at the connection between the inlet pipe and the heating system.
. The internal structure of gas water heaters is usually designed in a modular manner. The appearance of the water flow sensor is similar to a black cylindrical device, about the thickness of a finger, with a cable interface on the surface. When confirming the location, the device can be powered off and the front panel can be opened to search near the inlet port of the metal pipe below the machine. It is usually marked with the English label "FLOW SENSOR". Related functional linkage: This sensor monitors the water flow rate in real-time and, in conjunction with temperature sensors, achieves automatic ignition. When the user turns on the hot water faucet, the flow of water through the device will trigger the motherboard to start the combustion program. In recent years, some models have adopted magnetic induction sensors, which contain magnetic rotors and Hall elements inside. Daily attention should be paid to clean water quality to avoid impurities settling and affecting sensitivity. If ignition delay or unstable water temperature is found, priority should be given to checking whether
3. What can be used instead of a water flow switch (medium is water, water flow and stop, need to output a switch signal because of water flow...
Use water flow detection with a source circle that sells better, such as a Karman vortex street or glass rotor type. If only detecting flow and stop, a micro motion type can also be used.
.4. How to make homemade household gas flow monitoring equipment
Homemade household gas flow monitoring equipment has a low overall threshold and is suitable for novice electronic enthusiasts. The core process is divided into four core steps: material preparation, hardware connection, code writing, calibration and testing.
Preparation of required materials • Gas flow sensor: Priority should be given to thermal gas mass flow sensors (such as the commonly used FS1015 model), which are suitable for common household gases such as air and natural gas. Models with corresponding ranges can be selected according to the small flow requirements of household scenarios. • Microcontroller: Choose the entry-level Arduino Uno development board, which is easy to operate and has a large number of publicly available tutorials for reference. Display screen: The 1602 LCD display screen can meet household display needs, with low cost and easy wiring. Power supply accessories: 5V power adapter or power bank, providing power for the entire device. • Auxiliary accessories: breadboard, DuPont wires, used for quickly building temporary circuits2. Hardware connection - Connect the VCC pin of the gas flow sensor to the 5V pin of the Arduino, the GND pin to the GND pin of the Arduino, and the signal output pin to the
