Abstract
The use of a transmitter level detects the liquid level of a chemical percol tank instead of a level switch, because the transmitter level provides accuracy in reading the value of the chemical fluid level. Ease of installing the transmitter level can be programmed and set up easily. The high price of a transmitter level causes entrepreneurs in the industrial world not to use the transmitter level as a reader or detector of chemical fluid levels in the production process. Based on these considerations, the chemical fluid level control device percol was made using an ultrasonic sensor, by implementing the Atmega16 microcontroller as a controller. Controlling the level of chemical percol liquid level using ultrasonic sensor HC-SR04 as a reader or level detector. Drivers to run the motor when filling the chemical fluid tank of percol are run manually or automatically. The overall test results of ultrasonic sensors work optimally according to program settings. The average value of the ultrasonic sensor error to detect the level of fluid per tank 1 is 0.125 cm while the tank 2 is 0.0625 cm.
