Also in the device are the flow to the number of pulses 62 for gas flow meters, the drivers of the conversion factors 63, the second buffer register 64 and the third poll register 65..

The device operates as follows.

Unstable condensate from UKPG 36 through pipelines enters the gas processing plant. Before being supplied to the preparation, the unstable condensate enters the flow meter 37. Each flow is measured by its own flow meter. The secondary equipment of the device provides on these flows the registration of the measuring information for each flow and the determination of the total flow rate. The signals from the flow meter 37 are fed to the flow transducer to the number of pulses 1, in which they are amplified, converted into a sequence of pulses, and nop / I and c correspond to the calibration factor characteristic of each flow meter. Then the pulses come to the accumulation and indication unit 2, where the sum of the incoming pulses, the accumulation of measurement information

and indication of measurement results. In addition, the normalized pulses arrive at the first block of the first recalculation node 3, which adds and subtracts the incoming pulses. Consider this operation in more detail. The signals from the outputs of the flow transducers in the number of pulses 1 of each flowmeter are received at the first inputs of the corresponding elements C 4 of recalculation unit 3. The second inputs of these elements AND 4 receive signals of a periodic sequential polling from the first poll register 18. The polling frequency is selected on the basis of the standard sizes of the flow meters, at

5 according to the duration of the survey. During this polling time, the inputs of the binary adder 5 receive pulses from each of the flow converters in the number of pulses 1. (The channel is added and added together. After a corresponding time, the next polling channel is connected to the input of the binary adder 5. During the summation process, the results go through the first converter code 6 in the bugnare drive unit 7, where they accumulate. Then the accumulated sum of pulses from the buffer accumulator 7 is written as a binary number in a parallel return code to the double counter 12 every year The block workflow (polling and processing is set by the control unit 21. After being overwritten from the shift pulse generator 14 through AND 15,

5 which receives a signal through resolution trigger 13, triggered by binary counter 12 and polling registers 18, pulses arrive at the summing input of binary counter 12. The pulses arrive before the binary counter 12 is filled, which captures the total result from all connected converters 3 flow rate in the number of pulses 1 flowmeters 37.

five

In recalculation node 3, it is possible to connect any of the channels into the subtraction mode from the total amount, i.e. Pulses from one channel are added together, and pulses from the remaining 0 are subtracted from the original sum. The operation mode of the recalculation 3 for each of the connected channels can be set to subtract or interleave with the operation task block 9.

5 Suppose that the first several channels can be set to subtract or overlap using the operation task block 9. Suppose that the first several channels are key in the summation mode, and the last channels are in the subtraction mode. When polling the first channel, the first impulse will go to the trigger of sign 10 through the set task operation 9 and set it to state 1. With the direct output

In addition, trigger 1 potential is applied to code converters b and 8. This ensures the passage of the right cyMivEJ code from binary summer 5 to buffer 7, which is remembered for one clock cycle. From the output of the buffer accumulator 7, the summs of the sum through the second converter of code 8 is fed to one of the inputs of the binary adder 5. The transfer of the signal of the sum of the buffer accumulator 7 is provided by signals from the operation task block 9 via the II-KB element 11. The number of addition cycles is numerically equal to the frequency the arrival of pulses from the channel.

In the same way, the pulses from the other channels that are included in the summation mode are added. When the polling of the channel that is enabled for subtraction is reached, the first needle-pulse through the operation task block 9 transfers the trigger 10 to another position (this signal 1 comes from the inverse output (-) to the inputs of code converters b and 8. Now the inverse of the buffer accumulator 7 goes the sum code from the output of the binary adder 5, and the inverse code of the contents of the buffer accumulator 7 to one of the inputs of the binary adder. The summation of the pulses from the channels to the subtraction is performed in the inverse code, which is equivalent to the addition of the inverse In the same way, the total amount of pulses from other channels is also subtracted from the other channels to the reader. The resulting total of the incoming raw materials in binary counter 12 represents measurement information in bulk However, the raw materials coming from the installation 36 are characterized by considerable flow heterogeneity. In order for the measurement information to be presented in mass units, the measurement pulses are normalized and of the flow. For a given program (for example, after 1 h), the control unit 21 sends a command to the second switch 28, which connects the chromatograph 60 for analysis. The components of the chromatograph 60 generates electrical signals proportional to the percentage (volume or weight content of each component of the measured flow. The signals from the chromatograph 60 through the switch 28 enter the converter 29, where they are amplified and converted from analog signals into a series of pulses whose frequency is proportional to signal (voltage), Pulses divided by a multiple of.

determined by the measurement accuracy, are fed from the converter 29 to two counters 30 and 31. The first counter

30 fixes the integral of each individual component, and the second counter

31 is the value of the integrals of all components. At the end of the integration, the values of the parameters of each component are transferred to the second memory block 32. At the end of the analysis, the data is normalized in the division block 33 by dividing the value of the integral for each component stored in the memory of the block 32 by the number from the counter 31. From the division block 33 The signals in the binary code go to the average density calculation unit 34, which forms the signal of the average density of the measured product. The generated signal from the block 34 is fed through the distributor 35 to the control input of the decimal counter 19, which determines the conversion factor depending on the average value, the density of the measured flow

. in the process of accumulation of pulses by binary counter 12, the same pulses are fed to the counting input of the decimal counter 19, for which the coefficient of recalculation is set by the density signal from the previous analysis. From the last decade of the decimal counter 19, pulses have arrived at. the first memory block 20, which stores the measurement information generated by the density signal (mass units;; this is done according to the previous analysis, and the new analysis sets the conversion factor for the subsequent conversion. P1 accumulated data. the counter 12 and the first memory block 20 to the indicator 17, which ensures the registration of the total flow of raw materials in volumetric and mass units. In this case, the entire measurement information about the quantity from the indicator 17 is entered a first buffer register 27.

In addition to raw materials for the first installation

38Gas are supplied from the after-treatment process plants through the flow meter.

39 and off-spec product through the flow meter 40. Here, too, you need to know the total number of these auxiliary flows. The signal from flow meter 39 is fed to its flow converter to the number pulse 5% 62, where the analog signal is converted to digital, in the form of a binary code.
