How close to the tank wall can the 3300 transmitter be mounted?
Like the nozzle the tank wall can also affect the measurement through disturbance echoes. The minimum distance to the tank wall is the same as the distance to any disturbing object that may be present in the tank. If there are obstacles present in the tank the coaxial probe is the best probe to use. If the tank wall is metallic and smooth the probe can be mounted closer to the wall. For detailed information please refer to the 3300 Product Data Sheet, or the 3300 Reference Manual.
