1. Sonic nozzle calibration, high repeatability and high measurement accuracy;
2. Freely select temperature compensation and pressure temperature for more on-site use;
3. The circuit board is aging before leaving the factory, and the whole table is calibrated one by one, which is more suitable for field use;
4. Wide range of applications, gas, liquid and steam can be metered;
5. Low pressure loss, low energy loss, and energy saving;
6. Simple and firm structure, no moving parts, high reliability, low maintenanc.
temperature, instantaneous flow and cumulative flow of medium fluid in industrial pipelines, and has pulse output,
4-20mA analog signal output, RS485 communication (Modbus RTU protocol), GPRS of Internet and other functions.
