Product Description

product-1580-670

It 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.

product features

▲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.

working principle

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.
