Why does the ultrasonic cleaner need to keep the cleaning liquid within the allowable height of the liquid level indicator?
Maintaining the proper level allows the workpiece to be in the optimum flow and protects the heater and cartridge from damage due to overheating.
Improper liquid level will change the cleaning environment, reduce cleaning efficiency, and damage equipment
Ultrasonic cleaning system is a "tuning" system, the inappropriate level will change the cleaning environment, thus affecting the system frequency
