number, in order to correspond one by one.
 
 It adopts lithium battery power supplies, and can promise to use normally for over
eight years.
 
 The appropriation dynamoelectric valve promises a dependable switch.
 
The integral whole type designs, beauty and hard, water tightness, attack dependence and breakage dependences.
 
The LCD shows appearance of the amount of water, date, time, meter number, mode etc.
 
 Advanced alarm function: When the customer’s intelligence water has already closed, such as low power, communication abnormality etc. It can provide an alarm hint to the customer with the buzzer, so that the customer handles it as soon as possible, insuring customer to use water normally.
