ITEM NAME:Flowmeter Water Flow Sensor Home Liquid Measuring Instruments Practical Features: High accuracy, which can be up to 1~25L\MIN&;nbsp;  ±3%, good performance. Output pulse high level is more than DC 4.7V while input voltage is DC 5V. Silver and black electroplating design, looks exquisite workmanship. Made of metal material, durable and not easy to break, long term to use. Compact size, easy to carry with you and portable to use and operate.&;nbsp; Specifications: Material: Metal Color: Silver+Black Resistance to water pressure: &;gt;1.75 MPa Operating voltage range: DC5~15V Insulation resistance: &;gt;100 m ohm Accuracy: (1~25L\MIN)  ±3% Flow pulse characteristics :(11*Q) Q=L/Min ±3% Output pulse high level: &;gt;DC 4.7V(input voltage DC 5V) Duty cycle of output pulse: 50% ±10% Rated Voltage: DC 5V Thread: G1/2 Package Included: 1 pc* Water Flow Sensor Note: 1. Due to the light and screen difference, the item's color may be slightly different from the pictures. 2. Please allow 0.5-2 cm differences due to manual measurement..Duty cycle of output pulse: 50% ±10%. Flow pulse characteristics :(11 Q) Q=L/Min ±3%. 1 pc Water Flow Sensor. Resistance to water pressure: &;gt;1.75 MPa. Anyway we will try our best to avoid this kind of thing.
