Pressure Display Ultrasonic Water Meter

 

 

The ultrasonic water meter is a metering instrument to continuously measure, record, and display the volume of water flowing through the sensor by use of the ultrasonic time difference method. Please read this manual carefully before use, to use it to the best advantage and avoid unnecessary loss.

 

 

▲Unaffected by impurities, chemicals, and magnetic materials in the medium;

▲Low starting rate (33L/h), able to accurately measure the flow rate;

▲High measurement frequency;

▲Flow rate can be as low as 100L/h;

▲Dynamic range (Q3/Q1) up to 250:1;

▲Installed in any installation position;

▲Bidirectional metering;

▲Display of error and alarm codes;

▲Optional battery supply;

▲Material ductile cast iron;

▲No moving parts, high accuracy, and years of service life. The flow sensor has no moving parts, avoiding instrumentation failures of mechanical parts that can lead to inaccurate measurements due to long-term wear. The design is also resistant to impurities, making it inspection and maintenance-free;

▲ Low-pressure drop;

▲ IP68 protection class can adapt to a variety of harsh installation environments;

▲Support RS485 communication, pulse output, GPRS, NB-IOT, LoraWan, and other data transmission methods.

Ultrasonic water meter is a new type of water meter that can detect the time difference caused by the change of speed when the ultrasonic beam propagates in the water upstream and downstream, analyze and deal with the flow rate of water, and then calculate the flow rate of water further.

 

 

 

★Flush pipes before installation to avoid gravels 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;

★ Reserve an adequate space for maintenance 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 accuracy of the water meter;

★ The water meter shall not be installed at the place that may be affected by strong mechanical vibrations;

Special Notices: 1. 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;

★ If the ultrasonic water meter is installed through flange, make sure the parallelism between water meter flange and pipe flange is not more than 0.5% of flange outer diameter and is less than 2mm, otherwise it may result in damage to the water meter.

Installation Figure:

 

 

★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.
