The ultrasonic water meter is a new type of intelligent all-electronic meter. It integrates measurement and display to achieve accurate measurement with a minimum flow of 0.03 m3/h.

 

1) The ultrasonic water meter has no moving or blocking parts in the pipeline to be tested, no wear and low pressure loss.

2) The high sensitivity makes ultrasonic water meter can detect tiny change of flow.

3) Ultrasonic water meters can ensure accurate measurement throughout the entire life cycle, which does not change with time.

4) New type of intelligent all-electronic meter. It integrates measurement and display to achieve accurate measurement with a minimum flow of 0.03 m3/h.

5) Achieve multi-angle installation and minimize the pipe pressure loss.

6) Dedicated to household measurement in residential quarters.

7) Connect to the GSM wireless concentrator produced by our company, using GSM mobile public network for data transmission to form a wireless monitoring system. It automatically reports abnormal status.

Installation advice

1) The installed pipe must be filled with water. Install the meter on a vertical pipe in which the liquid flows upwards or diagonally upwards. If not, select a horizontal pipe. Try to AVOID installing the meter in a vertical pipe with the liquid flowing downwards or diagonally downwards.

2) AVOID installing meter at the highest point of pipeline to prevent the air bubbles accumulated and interfere with measurement.

3) Reserve a space at the water pipe for meter installation.

4) Concentrically align meter with pipe. Use a wrench to connect the pipe blade to meter thread and tighten it.
