  • Page 93 Reference Manual Configuration parameters 00809-0100-4480 September 2020 Upper null zone The Upper Null Zone defines how close to the transmitter's reference point a level value is accepted. You can extend this value to block out disturbing echoes close to the antenna, for example from the tank nozzle.

    The general threshold is used to filter out noise and disturbing echoes from the product surface echo. The transmitter uses certain criteria to decide which type of echo peak that is detected. Only echoes above the general threshold might be considered the product surface. Rosemount 1408H Level Transmitter...
