Abstract

PURPOSE:To facilitate handling by providing a wireless water level sensor instrument with detecting electrodes for detecting a water level in a bath, a sensor transmitter for transmitting a water level detection signal, a wireless bath call receiver for receiving the water level detection signal and a fixing member. CONSTITUTION:An instrument is provided with a proper quantity water level detecting electrode 1 for detecting a set water level A, a water leakage detecting electrode 2 for detecting a water level B in a water leakage condition, a fixing member 3 and a sensor transmitter 5 housing a transmitter 4 for transmitting a water level detection signal generated by detecting the water level by the electrode 1 or 2 as a radio signal. When the water level in a bath reaches the water level A, this is detected by the electrode 1, a water level detection signal transmitted from the transmitter 5 is received by a wireless bath call receiver 7 provided outside a bath room and a water level condition is informed by a buzzer sound 8. Further, when the water level falls by water leakage or the like to reach the electrode 2, the water level B is detected and the buzzer sound 8 is similarly generated via the transmitter 5 and the receiver 7.
