principle of operation
Before using this novel permanent liquid level electric gate, need carry out simple structure to whole novel permanent liquid level electric gate and know:
1. organically combining the electric gate 2 with the ultrasonic liquid level meter 1, setting high and low liquid levels, gate starting time and delay time, when the actual liquid level detected by the ultrasonic liquid level meter 1 reaches the set liquid level, automatically starting opening and closing countdown (delay starting) by the ultrasonic liquid level meter 1, after the countdown is finished, sending an opening and closing instruction to the electric gate 2 by the ultrasonic liquid level meter 1, correspondingly starting and closing the electric gate 2, stopping after starting for corresponding time, and entering the next detection process;
2. in order to prevent the electric gate 2 from being started frequently, the electric gate 2 is set to be started in a delayed mode through a time relay, when the liquid level detected by the liquid level meter reaches a set high liquid level, the gate opening countdown is started, and during the countdown period, if the liquid level drops below the set high liquid level, the countdown is automatically eliminated, and the gate opening instruction is cancelled; during the countdown period, if the liquid level is always higher than or equal to the set high liquid level, after the countdown is finished, opening the brake and starting, and reducing the liquid level; when the liquid level detected by the ultrasonic liquid level meter 1 reaches a set low liquid level, starting a gate closing countdown, and automatically eliminating the countdown and canceling a gate closing instruction if the liquid level rises above the set low liquid level during the countdown; during the countdown period, if the liquid level is always lower than or equal to the set low liquid level, after the countdown is finished, the brake is closed and started, and the liquid level rises;
3. because the stability of the liquid level and the starting and stopping of the gate have hysteresis, the gate is frequently opened and closed in order to prevent the liquid level from fluctuating up and down, then the starting time of the gate is set, and when the starting time reaches the set time, the gate stops and enters a liquid level detection stage; if the detected liquid level is still higher or lower than the high or low liquid level set by the liquid level meter, the liquid level meter enters the delayed starting program again, and after the delayed starting is finished, the liquid level meter sends a starting instruction to the gate again until the liquid level is stable.
