In case of Parshall flumes supplied by NIVELCO the location of the sensor is marked. In some cases foam may develop on the surface. Make sure that the surface, opposite to the sensor remain free of foam for proper sound reflection.

  • Page 29 Maximum Distance to be Measured (H) The maximum distance to be measured is the greatest distance between the surface of the transducer and the level to be measured. This is the only parameter that has to be programmed for each application other than distance (however to avoid disturbing effect of possible multiple echos it is suggested to do this in distance measurement applications too).
  • Page 30 P05: Minimum measuring distance (Dead zone- Close-end blocking) The EchoTREK will not accept any echo within the blocking distance set here. Automatic Close-end-blocking (Automatic Dead Band control) By using the factory default value, the unit will automatically set the smallest possible close-end-blocking distance i.e. the dead band. Manual close-end-blocking Manual close-end-blocking should be used for example to block out the echo originating from the bottom rim of a stand-off pipe or from any object protruding into the ultrasonic cone near to the transmitter.
