10.2 Quick Setup Guide
10.2.1 -
How to evaluate if the instrument is working properly
If in the display upper right, the ‘
R
’ letter is displayed, the instrument is working properly.
If the ‘
H
’ letter is flashing, it means poor signal input (refer to diagnostics chapter).
If the ‘
H
’ letter is displayed, it means no signal. If the ‘
H
’ letter is displayed, it means that instrument hardware is not
working properly (refer to troubleshooting chapter).
10.2.2 -
How to detect the fluid flow direction
1) Check that the instrument is working properly
2) If the display shows a positive value, the flow direction is from the “UP” to the “DOWN” transducer;
If the display shows a negative value, the flow direction is from the “DOWN” to the “UP” transducer
10.2.3 -
How to change the measurement units
The default value is the Metric System:
1) Use the
M30
menu to select the British system (in) for the pipe sizes, etc..
2) Use the
M31
menu to select the instantaneous flow rate measurement unit
3) Use the
M32
menu to select the flow totalizer measurement unit
10.2.4 -
How to enable and disable the totalizers
Use the
M34
,
M35
and
M36
menu to enable and disable the forward (POS), reverse (NEG) or net (NET) flow totalizer.
10.2.5 -
How to reset the totalizers
Use the
M37
menu.
10.2.6 -
How to use the delay time
The delay time acts as a filter to make stable the measure. By setting “0” in the
M40
menu, there is no filter.
The maximum setting is 9990sec, that refers to a response time of 9990 seconds.
The delay time is normally used 10s
10.2.7 -
How to use the low-cutoff
The value shown in the
M41
is called low-cutoff. The instantaneous flow rate measurements to below the low-cutoff
value will be displayed by the instrument with ‘0 ‘. In this way is avoided the invalid values accumulation.
10.2.8 -
How to calibrate the zero flow rate
Make sure that the flow has stopped completely and enter the menu
M42
for the calibration
10.2.9 -
How to change the correction factor (Scale Factor)
The correction factor is the ratio between the actual flow and the value indicated by the instrument.
The value is obtained during testing at our headquarters, by comparing the master flow measurement with the
DIMPU
unit flow measurement. For any changes, go to
M45
.
10.2.10 - How to enable protection password
The protection password prevents accidental configuration data changes.
Unlocking is possible by pressing the
key and entering the password.
To set the password to access the
M47
menu.
