Overview

Product model: LXSG-50~600 Product introduction: Pipe section ultrasonic flowmeter, which adopts the principle of ultrasonic time difference to achieve accurate measurement of flow rate. The instrument is equipped with M-BUS interface, RS485 interface, and 4-20mA interface. A remote meter reading management system can be formed through M-BUS bus and other communication devices. The management department can retrieve data from the meter at any time, facilitating the statistics and management of user water volume. The product complies with the calibration regulations of GB/T778 Measurement of Water Flow in Closed Full Pipelines for Drinking Cold Water and Hot Water Meters and JJG162-2009 Cold Water Meters.

Product Details
