In need of special note here is, a way to set parameters of the
differential pressure sensor. Parameters typically sensors provide differential
pressure cap, cap, comprising traffic flow coefficient, Reynolds
number, diameter ratio, expansion coefficient. The calculation formula
of the differential pressure sensor is usually:

C
Because each sensor manufacturers calculations of different, but usually
provide thedesign condition and design condition flow upper
limit, temperature, pressure. Therefore, the instruments used
in the calculation of design conditions according to the range
and density compensation, simplifies the instrument parameters setting. For
example, the application of standard orifice plate flowmeter measurement of
superheated steam flow, compensation formula is as follows:
designdensity fluid Working

The above list is that measurement principle of the sensor according to
Liquid Crystal Type Flow Totalizer

the formula, in the field of dimensional transformations often
need to flow. This point by setting the instrument measured discharge unit
and dimension can be realized after the conversion unit. The formula
for converting:
density of Conditionsunit flowflow volumeofCondition unit conversionafter lDimensionaflow mass ofCondition )()(
density Standard
density of Conditionsunit flowflow volumeofCondition unit conversionafter lDimensionaflow volumestandard The
)()(
In the formula is calculated according to the condition of density often
require the temperature, pressure and fluid type site, of course, can also be
a fixed density
The flow coefficient of unit conversion
For pulse input sensor, need unit and field measurement of the flow
coefficient of the factory calibration of flow units have different. Set the
instrument parameters, should be unified into a field unit for measuring the
flow unit. For example: the flow coefficient of the
sensor factory calibration is 32.1 pulses / L, the scene needs in accordance
with the cubic unit of measurement. You should set the parameters of
flow unit in the instrument settings for the M parameters fand /h, flow
coefficient is set to 32100 (pulse/ m3).
The density calculation
Saturation, superheated steam density, via the IAPWS-97 formula is
calculated bytemperature and pressure.
The density of water, the calculated by equation of order 3.
The density of the gas, by querying the standard density table obtained.

This function is selection function,when user ordering chosen
alarm points, just open related functions. You can choose 2 alarm
points at most.
Alarm Mode
Choose high limit means corresponding measurement value
upper limit alarm, choose low limit means Corresponding
measurement value lower limit alarm.
Choose preset reset means preset output on the cumulative flow,
at the same time reset the cumulative value.
Choose preset not reset means preset output on the cumulative
flow, and does not change the cumulative value.
After set the alarm mode parameters, the alarm type is divided
into two types: Measured value upper and lower limit alarm and
preset output cumulative value alarm.
Measured value upper and lower limit alarm
Sensitivity
In order to prevent measured values fluctuates near the alarm
set value caused alarm relay frequent action, according to need
to set an alarm to lift the epitaxial region.
Example: The upper limit alarm

Alarm delay
The range is 0~30 Sec, when set to 0 no alarm delay function.
When the measured value exceeds the alarm set value, it will
start the alarm delay, if during this time the measurements value is
always in a state of alarm, alarm delay over output alarm signal,
otherwise no output alarm signal.
The delay control Alarm restore also.
Preset output cumulative value alarm
Preset output advance(Alarm Sensitivity)
When the alarm mode choice as the preset reset or preset not
reset, the alarm sensitivity to determine the output advance.
Preset output actuation time(Alarm Delay)
When the alarm mode choice as the preset reset or preset not
reset, the alarm delay to determine the actuation time, the unit is Sec.
When set to 0 No automatic recovery.
Example: Asked alarm 1 preset output, the target value is
12.35m³, the advance is 0.05m³.when the cumulative flow reached
12.30 m³, alarm 1 output close, automatic recovery 10 Sec later, At
the same time the cumulative reset.
Alarm 1 point should be set in parameter group: Value: 12.35,
Mode: Preset Reset, Sensitivity: 0.05, Delay: 10.

10、Sensor And System Error Correction
How To Use Correction Of Zero Point And Full Scale
The instrument's zero and full-scale correction is mainly used
for error correction of sensors and connection caused by. The
factory instrument itself precision is tested qualified.
When there are fixed deviation in the whole measuring
range measurement value, can use zero correction. For example, the
reference temperature is 20.0 ℃ , instrument display 20.3 ℃ ; the
reference temperature is 89.3 ℃ , instrument display 89.6 ℃ , can
Liquid Crystal Type Flow Totalizer
-24-
be set the zero point to -0.3 ℃ . Zero correction value
= reference temperature- instrument temperature.
When the measured values closer to the greater the upper
range error, you can use full correction. Full correction before, should
first use zero correction will be zero alignment. Then set
the full correction: reference value divided by the meter display value.
The calculation formula for the instrument internal:
The final display value = (corrected before measurements + zero
correction value) * full correction value

Note 1: when the "medium compensation" setting for saturated
steam pressure, temperature signal is set to "formula" to realize
pressure calculated temperature.
When the "medium compensation" is set to the saturated
steam temperature, pressure signal is set to "formula" to realize
the temperature calculated pressure.

Note 2: " Pressure unit" Increase kPa, facilitate more occasions.
Note 3: For the gas flow temperature and pressure
compensation, Nm3 (standard cubic) is calculated by using the
"standard conditions of temperature setting temperature
value for reference
Note 4: when the "medium compensation" is set to saturated
or superheated steam, the temperature is lower than
the "threshold temperature" flow display is 0, stop the
accumulation.
Note 5: when the "medium compensation" is set to gas, the pressure
is lower than the "pressure threshold" flow display is 0, stop
the accumulation.
Note 6: "flow time filtering" said average filter so long
time to flow. This parameter is only for the instantaneous flow
calculation, the value is not valid frequency pulse.
Note 7: for cumulative excess coefficient of instantaneous flow
rate multiplied by the upper part of the.
Note 8: "Protocol" is chosen as "TC ASCII" or "MODBUS-RTU", the
user can choose according to need.
Note 9: "backlight brightness gradient" is set to "open", no button
operation after 10 minutes, the LCD backlight brightness auto
dimming backlight brightness, automatically
improve key operation; is set to "off" when the backlight has been at
the bright state,suggested that the user of this parameter is set
to "open".
