No Moving Parts, high accuracy for years long. No moving components in the flow sensor, avoid long-term abrasion of mechanical parts which may result in inaccuracy measurement and failure of the meter. Such design is also resistant to impurities, therefore no inspections and maintenance are cost-free.

PRODUCT INTRODUCE

Best portable ultrasonic flow meter of small diameter.

Ultrasonic water meter is a new type of water meter that detects the time difference caused by the change of velocity when the ultrasonic beam propagates in the opposite direction of the water, and analyzes and processes the ﬂow rate of water to further calculate the ﬂow of water.

Notices for Installation

 Flush pipes before installation to avoid gravel and other foreign objects;

 Install a valve and filter before the water meter;

 Do not touch the electrical part or pull wires to avoid damage during installation;

 When the water meter is installed in a horizontal or inclined way, the ultrasonic flow probe on pipes shall be placed horizontally, and  when installed in a vertical way, make sure the water flows from down to up.

 Please note that the arrow direction on the pipe shall be consistent with the water flow direction during installation;

 The joint washer shall be installed correctly to avoid misaligned washer blocking water and affecting the accuracy of the water meter;

 The water meter shall not be installed at a place that may be affected by strong mechanical vibrations; Special Notices:

Be sure to install an on-off valve and filter before the water meter and another on-off valve is recommended after it for maintenance.In order to prevent backflow, a check valve should be installed in front of or behind the water meter.

 Before using this water meter, the pipe must be filled with water, otherwise it will lead to inaccurate or even non-measurement;

 When installing the water meter, should be reserved length of DN*10 in front of the water meter. Or should be reserved the length of DN*5 behind the water meter;

 The water meter shall refresh the display at every 4s, and read the water meter (including the starting value and end

value) 4s at least after the valve is closed when test the water meter, otherwise the testing results may be affected;

 Please make sure the medium flow is within the flow range of the water meter during test and use, otherwise it may result in damage to the water meter;

 In case of any malfunction (e.g. metering failed, etc.) during use, please contact the related management department

immediately and do not repair it by yourself;

 The product is designed with a disposable anti-disassembly seal which shall be removed only by appointed personnel, or otherwise it shall be excluded from the free after-sales service.
