1. Limits
Admitted relative error of complexes of updatings "FLOUTEK-TM-1" and
"FLOUTEK-TM-2" at measurements volumetric (mass flow) the charge and volume (weight)
of environment (without taking into account a component brought by methodical
errors at use The standard narrowing device or осредняющей a pressure head tube)
make from ±0,3 up to ±2,0 % (depending on an error of measuring converters
Temperatures, pressure, difference pressure and density and ranges of change
Pressure and pressure difference of environment on the specified devices).
Limits of an admitted relative error of complexes of updatings "FLOUTEK-TM-3"
And "FLOUTEK-TM-4" at measurements volumetric (mass flow) the charge and volume
(weight) of environment (without taking into account an error of the counter or a
flowmeter) make from ±0,3 up to ±0,8 % (depending on errors of measuring
converters of temperature, pressure And density and a range of change of pressure
of environment).
2. Limits of the admitted resulted error
Complexes at measurements of pressure make ±0,075; ±0,10; ±0,15 or
±0,25 % of the top limit of measurements.
3. Limits of an admitted absolute error
Complexes at measurements of temperature make ±0,5 °С or ±0,75 °С.
4. Limits of an admitted absolute error
Complexes at measurements of density make ±0,003 kg / m3.
5. Complexes provide installation (under the order)
The top limits of measurements in a range:
• for absolute (superfluous) pressure ....................................... - from 160 кПа up to 16 МПа;
• for differential pressure ......................................................... - from 1,0 up to 250 кПа;
• for density of gases under standard conditions ....................... - from 0,7 up to 1,1 kg / m3;
• for density of liquids ............................................................. - from 500 up to 1200 kg / m3.
6. A range of measurements of temperature......................... - from a minus 40 up to plus 100 °С.
7. A maximum quantity of the last day, for
Which data recording in memory of calculator VR are kept:
• at service of one pipeline ....................................................... - 108,
• at service of two pipelines ...................................................... - 54,
• at service of three pipelines .................................................... - 36.
The maximal period of time, for which in memory of converters - proof-readers
The PK - 1 and the PK - 2 are stored records:
• the daily data ........................................................................ - last six months;
• the hour data ......................................................................... - last two months.
8. An electric feed of complexes is carried out
From a network of an alternating current a voltage from 160 up to 250 V and
frequency (50 + 1) Hz. Complexes have the reserve power supply of a direct current
(accumulator) in rated voltage 12 V which provides preservation measuring
Information and normal work of complexes during not less 100 h.
9. The capacity consumed by complexes, does not exceed:
• at a feed from a network of an alternating current a voltage 220 V and
frequency of 50 Hz - 14 VA;
• at an independent feed from the accumulator in rated voltage 12 V - 1,7 Wt.
10. Average full service life - not less than 12 years.
