Setting Zero Head
Many PMDs start flowing higher than the traditional empty distance of the application.
You can account for the flow in one of two ways:
1.
Use P605 (Zero Head) to have OCM calculations ignore levels below that value.
Possible head = P007 minus P605.
2.
Use P801 Range Extension where the Empty level is set to the bottom of the weir,
and above the bottom of the channel. It should be used if the surface monitored can
fall past the Empty (P006) level in normal operation without reporting an LOE. The
value is added to Empty (P006) and can be greater than the range of the transducer.
The examples on the following pages show both methods.
Note: P603 (Max. Head) is preset to P007 and is not updated when P605 is used.
Make sure you set P603 to the correct value when using P605.
