Operation
The meter shall display instant, accumulated and
peak-valley flowerate. The indication light shall be
lighted accordingly. Please see the detailed
description below.
Instant flowrate display
1. Instant flowrate is a default display mode, both
2. Instant flowrate is displayed by 4
LED
3. When the instant flowrate is over the allowed range, I-
min) will be flashing.
4. If I-
LED
and -
II LED
flash at the same time, it indicates that the actual flowrate is over the
calibrated range or the display value is incorrect.
Accumulated flowrate display
1. The accumulated flowrate is displayed by 8 digits that is separated with two 4 digit
display where I-
LED
indicates the first 4 digits and -
units is
SL
.
2. The accumulated flowrate can be reset via the keyboard.
NOTE The flow accumulation will be saved every 3 minutes. For instance:
:
Ÿ
The flow accumulation will not be saved if power off @ 2 minutes.
Ÿ
The flow accumulation will be the value of 33 minutes if power off @ 34 minutes.
Peak-Valley flowrate retrieval
1. The data of the last registered peak-valley flowrate can be retrieved via the keyboard.
2. When the peak flowrate value is displayed and flashed, the I-
3. When the valley flowrate value is displayed and flashed, the -

Keyboard lock
This function shall prevent unintended changes of the parameters by press the keyboard.
When keyboard is locked, the menu function is disabled.

Offset reset
This function shall reset the offset which may be due to drift after a certain period of
performance. It shall help for improving accuracy.
make sure there is no flow in the meter otherwise it will have impact to the accuracy.
Sampling time

This function allows user to set the sampling time between analog output and digital
output via the serial port. Once the setting is done, it will be immediately effective but the
