【 Selection Tips 】
The following parameters need to be determined in detail when selecting: pipeline diameter, pipeline material, measuring medium, and process
Temperature, working pressure, installation method (external binding, insertion, pipeline), power supply (24V or 220V),
Output mode (4-20mA, pulse output or 485 communication), maximum flow rate (working state or standard state), whether required or not
