Description

Features
Dual-channel ultrasonic probe is used to measure the pipeline. The measurement is accurate and reliable with no moving parts; Wide range ratio and low starting flow; With electronic lead sealing function;
Positive and negative measurements can be made;Display abundant information, display 12-digit cumulative flow and 5-digit instantaneous flow in the same interface; With intelligent power-saving design, the instrument will turn on the power-saving mode in the static state of fluid or empty pipe;There are many kinds of communication interface
modes: RS485 interface, MBUS, MODBUS. infrared interface, support CJ-188 communication protocol and MODBUS protocol;Optional RS485,MBUS,NB-OT,LORAWAN; Pulse output, easy to connect with other equipment; All IP68 protection grade design, all components are fully sealed protection, even if the water can work normally for a long time;It has the function of temperature measurement;
According to different customer needs ,There are a variety of unit systems,including m³, USG, ft³,L;Built-in lithium battery, more than 5 years opbattery life,tional external 24V power supply.
