Quantitative injection circuit board development
Technical parameter description of the solution:
1. The quantitative filling controller uses high-performance CPU as the core and adopts a modular design. Its main features are complete functions, simple structure, clear interface and easy operation.
2. It can be conveniently applied to the quantitative and fixed amount filling control of various liquids such as diesel, lubricating oil, methanol, water, chemical solutions.
1. Large single-screen LCD display can display unit price, amount, and liters. At the same time, the buttons also have LCD display, which is convenient for quantitative and fixed amount filling.
2. Single pulse and double pulse flow meters can be used, suitable for 12V/24V vehicle filling, low voltage protection function.
3. The pulse equivalent can be automatically calibrated inside the factory, which reduces the error caused by the pulse equivalent, thereby improving the measurement accuracy.
4. Real-time error coefficient adjustment, the error coefficient is maintained after power failure. The error coefficient can be set by pressing the button, the setting range: 0.1000---9.9999.
5. All parameters can be saved when power off to avoid data loss caused by power off.
6. Pulse equivalent calibration, clearing of accumulated flow, clearing of accumulated flow of shift, and restoring to factory settings all require the correct password to operate, ensuring data security.
7. Remaining display after power failure. If the power is off accidentally, the screen can keep displaying for more than 5 minutes. If the power is all consumed, the last displayed value will be displayed again after the next power on.
