LIQUID LEVEL DETECTOR

摘要: PURPOSE:To always enable of accurate detection on whether a liquid level in container is above or below specified by forming side wall part close to from an ultrasonic transmitting material. CONSTITUTION:An transmitter 55 and receiver 56 are mounted mounting plate 54 provided one 51. Then, when the 52 51 level, wave S emitted reflected with reflector 53 being little attenuated as S'. A controller 57 compares signal high reception set value output judgment that level. When space so much it reaches 56. Thus, lower than emits
