8.Parameters you need to know
1. The type of medium to be measured (liquid or solid, specific name, clear water, sewage, mud, gasoline, diesel, toluene, sulfur dioxide, etc.) If it is liquid, whether there is steam, mist, foam, waves, stirring, floating objects on the liquid surface ; if solid, whether there is dust.
2. The temperature and pressure of the medium.
3. The corrosiveness of the medium. If it is placed in a jar, it is necessary to know whether the material of the jar has an anti-corrosion lining.
4. The measurement range is a few meters and the blind spot is required.
5. Working environment: such as open pools, pools with covers, horizontal tanks, vertical tanks, spherical tanks, whether the tank is at atmospheric pressure, etc.
6. Working voltage: 24VDC, optional 220VAC can be customized 12VDC/9VDC common power.
7. Output signal: 4～20mA current 485/0-3V, 0-5V voltage output/relay output.
9. Equipment form: whether it needs to have a display; one-piece or split-type.
