Calibration validation by NMI laboratory

Portable analyzer and processor of isokinetic parameters, able to measure and calculate with relation to physical quantities such as Temperature, Air speed, measurement of static and dynamic pressure and measurement of atmospheric pressure, directly calculating normalised air volume. Equipped with a double sensor for operating pressure detection to allow for further accuracy in ranges even with the lowest available minimum levels.

Equipped with a special area and drop number calculation, including for stacks with sections differing from standard circular stacks. The back-lit display shows all quantities in real time and their corresponding calculations for setting sampling devices and related accessories. All measurements and respective data can be memorised and downloaded on a PC by means of external software via RS232. The Isoflow 201 processor is interfaced with a sampler board (AirCube, AirFlow) and allows for use of the sampler in real time Isokinetic mode, modifying to change the sampler flow rate for emissions situation changes and permitting adjustments to sampling development. An easy, guided menu allows the operator to visualise all set and memorised data and to modify them even during the sampling phase.

Other features are:
• Measurement range, see following technical information
• Operating range -10/+40°C
• Pressure detection: double sensor with automatic scale change (see following Pro version technical information)
• Dimensions: 20x10x6 cm
• Weight: 950 grams
• Data output: RS232 bi-directional
• Rechargeable 12Vcc NiMH power

The Isoflow 201 measurer is supplied complete with: power feed/battery charger, case for transport and user manual in Italian, pipe fittings and cable for temperature sensor.

“Measurement range” is intended as the range of validity of supplied characteristics. Errors reported at the bottom of the scale, specified in the operating range with calibration at 25°C.
1) Characteristics of temperature input are strongly influenced by thermocoupling characteristics utilised, therefore supplied characteristics in this section relate to input precision of read voltage effects. The value of applied voltage is then converted into a temperature utilising algorithms of inverse conversion specified by ITS-90 with ninth degree polynomials. Therefore, obtained conversion errors would be less than 0.05°C.
2) Maximum pressure which can be applied without damaging the sensor.
3) Range to which instrument precision refers.
4) Maximum allowed differential pressure between inputs.
5) Precision is substantially the result of the non linearity and hysteresis of the pressure sensor. Offsets are all compensated with calibration. Also thermal effects on sensor offset are intended as calibrated with a calibration process. .
6) Variation in reading of instrument position differing from the specified position.
