value
Return line
□
Line from the consumer back to the reservoir
Scale
□
Assigning of a maximum input value to a maximum output value
Serial interface
□
Sends or receives data in chronological sequence
Single-line measurement
□
The values of a volumeter are measured and evaluated
Square wave signal
□
Pulse signal
with square wave form
Supply line
□
Line from the reservoir to the consumer
Temperature
compensation
□
Consideration of the current temperature at the
volume
and
mass
calculation
in order to compensate density changes
Temperature input
□
Processes signals of a
temperature sensor
Temperature sensor
□
Converts the physical value temperature into an electrical value
(e.g. resistance)
Threshold
□
Value at which an action is triggered when it is overpassed or
underpassed
Total
□
Volume values that have been measured since the last reset
Total consumption
□
Quantity that has been consumed since the last reset
Total flow
□
Quantity that has passed the volumeter since the last reset
Updating rate
□
Shortest period in which a change is displayed in the display
Volume calculation
□
The volume is converted to a standard temperature by means of the
density table and the temperature
Volume measurement
□
The volume that passes the volumeter is calculated from the
K-
factor
[P/l] and the pulses of the volumeter
