CHARACTERISTICS
1. High precision measurement
Linearity better than 0.5%, repeatability accuracy better than 0.2%, measurement accuracy better than ± 1%
2. Large measurement range
By selecting different types of sensors, it is possible to measure the flow rate of pipelines with diameters ranging from DN15 to DN6000mm
3. High protection level
The one-time protection level of the meter can reach IP68 by adopting the fully sealed waterproof process, and it can work underwater for 2 meters
4. Easy to operate
Both magnetic rods can be used to browse parameters on the secondary table, and parameters can be reset or displayed in Chinese through the secondary table
5. Multiple Display
The first meter can complete the measurement at the measuring point, and the first meter can cyclically display parameters such as cumulative flow rate, instantaneous flow rate, and flow velocity. The second meter canMore than 100 menus displayed in Chinese
6. Long transmission distance and fast networking
RS-485 bus communication is used between the primary meter and the secondary meter (or computer), using ordinary cables, with a transmission distance of up to 1000 metersUp,Networking is very convenient and fast. This transmission method has strong anti-interference ability and solves the cost of dedicated cables for split type ultrasonic flow metersHighanti-interferenceProblems such as poor capability and short transmission distance.
