Notes on flow compensation coefficient Kx:

When Level 2 parameter KE = 1, nonlinear compensation of flow input can be achieved through

Level 1 parameter Kx. The figure of compensation coefficient K is as follows:

Nonlinear input signal of flow can be compensated through setting coefficient Kx; This function can be also used for small signal cut-off of frequency input; Flow rate (linear, differential or frequency) of the input value is less than 1/3, the coefficient K1 for compensation; flow rate (linear, differential or frequency) of the input value is greater than the FH by K4 as coefficient compensation. For linear compensation, Level 2 parameter KE will be generally set to be 0, so only parameter K1 will be served as compensation coefficient in Level 1 parameter setting, and K2, K3, K4 will not be displayed. Note: this function is invalid in the case of frequency input, in which case error will occur to the program if this parameter has been set. Control output type (AL1, AL2, AH1, AH2)

during fluctuation of output relay at output critical point; it works as followed:

AH2 means control output lead value. Upon control output of the instrument, if there’s still instantaneous flow input, it will continue to be accumulated. Upon the control output, current control is completed. Manual start is required for next control upon which control output will continue. Method of starting quantitative control of flow in AL2 (AL2: manual start of quantitative control) 1. Press the external switch of “Start”, and it starts quantitative control of flow; 2. Set Level 1 parameter LOC as 111, and in the status where PV window displays measured value,

press

to start quantitative control of flow.

Method of stopping quantitative control of flow in AL2 (AL2: manual start of quantitative control): 1. Press the external switch of “Stop”, and it stops quantitative control output of flow; 2. Set Level 1 parameter LOC as 111, and in the status where PV window displays measured value,

press

and simultaneously to stop quantitative control output of flow.

When key “Stop” is pressed, control output will be stopped no matter whether there’s quantitative control output; if there’s still instantaneous flow input at this time, it will be accumulated. In order to initiate quantitative control output of cumulative flow, quantitative control output of flow must be “started” again.

Current cumulative value will be cleared in case of power failure or reset. Press

and

simultaneously for manual clear of value. In case of quantitative control with external switch, press external switch “Clear” for manual clear of value.
The total cumulative value will be cleared when it reaches full 11 digits. In case of need for clear before it reaches full 11 digits, set Level 1 parameter LOC as 111, and in the status where PV window

displays measured value, press

and

simultaneously for manual clear. In case of quantitative

control with external switch, press external switch “Clear” for manual clear of value. The maximum cumulative flow of the instrument is 99999999999, and Level 2 parameters can
be set to change display form within the range of 99999999.999 to 999999999.99. 4.2 Level 2 parameters setting

Note1: T-b, T-k, P-b, P-k, F-b, F-k calculation formula:

X-k = set full range ÷ (original full range × original X-k)

X-b = lower limit of set measuring range {lower limit of original measuring range × (X-k) + original (X-b) }

Take one instrument with pressure compensation of 4~20mA and measuring range of 0~2MPa for

example. At the time of calibration, it’s found that in case of 4mA input, it will display -0.03 and in case of 20mA input, it will display 2.08. (Original P-k=1.000, original P-b=0)

Signal / Meter Flow computer Based on the formula: P-k = set full range ÷ (original full range × original P-k) = (2-0) ÷ (2.08 – (-0.03)) = 2 ÷ 2.11× 1.000 0.94787 P-b = lower limit of set measuring range (lower limit of original measuring range × P-k + original P-b} = 0 – (-0.03×0.94787) + 0 0.02836 So now It’s set that P-b = 0.02836, P-k = 0.94787 Note 2: the setting of output shift of O1-b, O1-K, O2-b, O2-K is as follows: Instrument transmission output will be collated at 0-20mA or 0-5V; change of output range or output error correction may be realized by the following formulas:
Where in case of current signal output, full range = 20; in case of voltage signal output, full range = 5. Example 1: transmission current output 0-20mA is now desired to be changed to 4-20mA output. In
case of zero input, the output is 0mA; in case of full range of input, the output is 20mA; current Oub=0, current OuK=1.
Therefore, if Oub is set to be 0.2 without change of OuK, the 0-20mA output will be changed to 4-20mA.
Small signal cutoff: when measured value of instantaneous flow is less than CAA, instantaneous flow will be displayed as zero, and the flow will not be accumulated.
In parameters setting, if required parameters are not available currently, the following parameters may be set first. After one cycle of setting, the require parameters may appear as they may be closed by the following parameters.
The unit in parameters setting must be the same as that for actual measurement. In the case of saturated steam measurement, either temperature compensation or pressure compensation may be selected. Print interval: Pr-T = 0 is not printed, the print format right:

Level 3 parameters are used for automatic calculation of flow coefficient K. It gives user great

convenience to set parameters and improve the instrument’s user-friendliness. Before setting of Level

3 parameters, Level 2 parameters setting shall be completed to determine instrument type, display

precision, input type, compensation range, measuring range and unit. And then we can enter into Level

3 parameters setting to set maximum instantaneous flow A-Q, operating flow A-F, operating

temperature A-T, and operating pressure A-P. The instrument will automatically calculate the flow

coefficient A-K based on Level 2 parameters and upper limit of measuring range (differential pressure)

Frequency voltage range can be regulated as follows: Voltage regulation: 1. Regulate upper limit of input voltage: regulate potentiometer W1 (clockwise rotation for decrease and counterclockwise rotation for increase) so that voltage at negative end of frequency input of pin pair 7 of LM339 is not more than upper limit of input voltage.

2. Regulate lower limit of input voltage: regulate potentiometer W2 (clockwise rotation for decrease and counterclockwise rotation for increase) so that voltage at negative end of frequency input of pin pair 8 of LM339 is not less than lower limit of input voltage.
Regulate W1 and W2 to keep the amplitude of upper limit / lower limit of voltage is within the range of wave shape. The voltage is preset as about 2.5V and 4.5V for lower limit and upper limit amplitude.

X. Programming Examples

Some gas is measured with orifice plate with input of differential pressure as well as pressure and

temperature compensation without output; it’s required that no cumulation will be made when the

differential pressure is less than 10KPa. Relevant parameters are as follows:

Differential pressure transducer: 4~20mA; measuring range: 0~80KPa

Pressure transducer: 1~5V; measuring range: 0~3KPa Temperature transducer: 4~20mA; measuring range: 0~300

Atmospheric pressure at the site where the instrument operates (PA): 0.08 MPa

Signal / Meter
Flow computer
Density in standard condition: 20 = 2Kg/m3 When operating pressure (compensated pressure) P = 3MPa and operating temperature T =300, the maximum flow M = 100T/h. Instrument model selection: NHR-5600A-27/29/27-X/2/X/X-A Based on the formula:

The parameters are set as follows:
