15.1.1 Volume flow rate
If you select the function "volume flow," the following will be displayed (example):
Volume flow
100.0 l/h
The LCD shows the current volume flow rate. You define the display unit in the functional
class FLOW using the function "volume flow unit".
15.1.2 Forward flow counter 1
Forward flow counter 1 and forward flow counter 2 are independent counters that can also be
reset separately. With counter 1, for example, you can measure the yearly or monthly volume.
If you select the function "forward flow counter 1", the following will be displayed (example):
Counter 1 forw.
+ 000001.0 l
The LCD shows the current value of forward flow counter 1. You define the display unit in the
functional class COUNTERS using the function "unit of counter".
15.1.3 Forward flow counter 2
The function is identical with the function of forward flow counter 1. For example, forward flow
counter 2 can be used as a daily counter. If you select the function "forward flow counter 2",
the following will be displayed (example):
Counter 2 forw.
+ 000001.0 l
The LCD shows the current value of forward flow counter 2. You define the display unit in the
functional class COUNTERS using the function "unit of counter".
15.1.4 Reverse flow counter
If you select the function "reverse flow counter," the following will be displayed (example):
Counter reverse
000000.0 l
The LCD shows the current value of the reverse flow counter. You define the display unit in
the functional class COUNTERS using the function "unit of counter".
15.1.5 Flow velocity
If you select the function "flow velocity," the following will be displayed (example):
flow velocity
1.5 m/s
The LCD shows the current value of the mean flow velocity of the medium. The display unit is
always meters per second (m/s). The mean velocity is calculated from the measured volume
flow and the flow area of the meter tube. In order to calculate the flow area of the meter tube,
enter the inside diameter of the meter tube. To do so, use the "inside diameter" function in
the functional class SETTINGS ELM.
