which stand for the total flow is over 100 cubic meters during the period of every
day from 20:00 to 06:00, setups is like
M51 start time =20:00:00
M51 interval =10:00:00
M51 log times =9999 (means always)
M80 select item #9
M81 input 100 (Unit is defined in M30,M31,M32)
M81
The built-in batch controller
Set the flow batch value(dose)
The internal output of the batch controller can be directed either to the OCT or the
RELAY output circuits.
M81 and M80 should be used together to configure the batch controller.
Note: Because the measuring period is 500mS, the flow for every dos should be
keeping at 60 seconds long to get a 1% dose accuracy.
M82
View the daily, monthly and yearly flow totalizer and thermal energy totalizer value.
The totalizer values and errors for the last 64 days, 32 last 32 months and last 2
years are stored in the RAM memory, To view them, use the ‘ENT’ and ‘UP’ ‘Down’
keys.
M83
Automatic Amending Function for automatic offline compensation.
Select ‘YES’ to enable this function, select ‘NO’ to disable it.
When the function is enabled, The flow meter will estimate the average flow
uncounted (or ‘lost’) during the offline session and add the result to the totalizer.
The estimation of the uncounted flow is made by computing the product of the
offline time period and the average flow rate, which is the average of the flow rate
before going offline and the one after going on line.
M84
Set the thermal energy unit:
0. GJ 1. KC 2.KWh 3. BTU
M85
Select temperature sources
0. from T1,T2 (factory default)
1. from AI3,AI4
M86
Select the Specific Heat Value.
Factory default is ‘GB’. Under this setting, the flow meter will calculate the enthalpy
of water based on the international standard.
If the fluid is other than water, you should select option ‘1. Fixed Specific Heat’, and
enter the specific heat value of the fluid.
M87
Turn on or turn off the Energy totalizer.
M88
Select thermal energy totalizer multiplying factor.
Factory default is ‘1’.
M89
1. Display the temperature difference
2. Window for entering the lowest temperature difference.
M90
Display signal strengths S (one for upstream and one for downstream), and signal
quality Q value.
Signal strength is presented by 00.0 to 99.9, the bigger the value, the bigger the
signal strength will be, and more reliable readings will be made.
Q value is presented by 00 to 99, the bigger the better. It should at least be great
than 50 for normal operations.
