11.7 Flow Calculation
Conguration
The number of volume pulses arriving in a predetermined time interval
(minimum/maximum waiting time).
authorised test centres.
11.7.1 Calculation of the Flow Rate with Conventional Flow Sensors
in litres/pulse or the time for a measuring period in seconds.
Flow rate (l/h) kw × 3,600 × imp/time
kw (litre/pulse) pulse valence
Imp number of pulses per measuring period
Time duration of the measuring period [s].
11.7.2 Calculation of the Flow Rate with Fast Flow Sensors
pulse/litre.
The formula applies accordingly:
Flow rate (l/h) 3,600/time × Pulse/pf
pf (pulse/litre) pulse factor
Pulse number of pulses per measuring period
Time duration of the measuring period [s].
11.8 Temperature Measurement
11.8.1 General Information
Approved according to MID, the measuring range is 2 °C to 200 °C. There is no approval be-
low 2 °C according to today’s valid approval regulations.
As standard, the Supercal 5 is designed for Pt500 temperature sensors. The temperature
sensors can be connected using two-wire or four-wire technology. The temperature meas-
urement itself is carried out according to the “dual slope method”. An integrated calibration
system ensures high measurement resolution and measurement stability.
If the equipment is connected to a 440, the measurement timing is:
Between 3 seconds and 30 seconds if the calculator
has an external power supply.
Between 10 seconds and 30 seconds if the calculator has no external power supply.
Between 3 seconds and 120 seconds if the calculator
has an external power supply.
Between 10 seconds and 120 seconds if the calculator has no external power supply.
