C. Installation Guide
- Place the sensor where there are no obstacles between the emission surface and the liquid being measured. Ensure it is away from feeding points to avoid interference.
- Consider the tank shape. Conical or spherical tanks may cause secondary echoes, so choose a suitable installation location to minimize errors.
- Install the sensor using flange or threaded connections. Make sure the sensor is properly mounted through the hole or flange.
- If measuring liquids with impurities, sludge, or turbulence, use a waveguide with a diameter larger than 120mm to improve accuracy.
