Please note that the user should also select option 13 "Frequency Output" in
window M78, and also make the hardware connection for OCT output.
3.16 How to set the cumulative pulse output
Each unit of flow, SUP-2100H ultrasonic flowmeter can generate a cumulative
pulse output to the external counting device.
Flow units and multiplication factor settings in 3.4, 3.5.
Accumulation pulse can only be through the hardware OCT or buzzer.
For example, if you want to use a buzzer to output positive accumulation pulses,
each pulse representing 0.1m3 of flow, so that the buzzer will sound for every
0.1m3 of liquid flowing through the pipe.
Please follow the steps below:
In window M32, select the cumulative flow unit: "cubic meters (m3).
In window M33, select the multiplication factor: "x 0.1".
In window M77 select: "Positive cumulative pulse output".
3.17 How to generate the output alarm signal I
Ultrasonic flowmeter can generate two types of alarm signals: audible alarm signal
and switch output alarm signal. The following conditions can be used as the buzzer
and switch output trigger source:
The probe does not receive the ultrasonic signal.
The probe receives the ultrasonic signal too poorly.
The flow meter is not in the normal measurement state.
The flow rate is reversed.
The frequency signal is out of range.
Instantaneous flow rate is out of range.
There are two alarms, called: Alarm #1 and Alarm #2. The user sets the output
range in windows M73, M74, M75, M76.
For example, when the flow rate is less than 300 m3/h and more than 2000 m3/h,
the buzzer will sound, and the setting process is as follows:
Enter the lower flow rate of 300 in window M73 as the #1 alarm trigger point.
In window M74, enter the upper limit flow rate of 2000 as the #2 alarm trigger point.
Select "6. #1 Alarm" in window M77
