Velometer  is a highly reliable and handy instrument realized for the control of temperature variations and ΔP in conveyed flows, to calculate their speed. Coupled with all kinds of our probes, Velometer gives an instantaneous reading of the pressure difference via a needle transducer and displays the flow temperature through a high precision display.Iit is supplied with hose, plywood connector for connection to the thermocouple and power cord.

Instruments are available with different ranges:
• Velometer 20: range 0-25 mm H₂O (code A.3007)
• Velometer 50: range 0-50 mm H₂O (code A.3008)

ISOBOOK α is a portable meter of emissions speed compliant with UNI EN 13284 and 16911, ISO 9096.

Thanks to electronic transducers of ΔP, temperature and pressure connected to Darcy pipes and thermocouples, the instrument allows total characterization of any emission for sampling in perfect isokinetism. It’s known that a proper definition of dust concentration in emission requires the adoption of sampling techniques providing maintenance of the isokinetic regime during the entire processus. This condition is obtained by means of an accurate and continuous measurement of the fumes speed and control of the sampling isokinetic flow rate.
ISOBOOKα has been conceived to fix these problems and has been realized using modern miniaturized computer systems combined with great precision and small-size measuring sensors. The heart of ISOBOOKαis a small computer which, connected to ΔP, pressure and temperature sensors, is able to acquire and check all the thermodynamic parameters of the fluid in emission, automatically calculating both fumes speed and the correct isokinetic flow.
The different operating menus of the program also allow the complete characterization of the chimney, according to the regulations defining both the number of sub areas and the points to be examined in the duct with the relative distance from the edge.
Once the preliminary velocity measurements and the calculation of the ideal nozzle diameter to fit in the sampling probe have been made, ISOBOOKα calculates the isokinetic rate that the operator shall have to adjust on his/her own air sampler. This data, fundamental for a correct sampling, is then updated on the basis of new speed measures according to a user-specified frequency, giving constant information about any new sampling condition to allow a continuous sampling control.
As previously said ISOBOOKα has a structured program menu briefly described

Definition of the duct geometry 
With this first subprogram the user can identify the emission, through the assignment of a number that will help him to retrieve stored data when necessary, and, also, to introduce the geometric data of the conduit getting from the computer calculation of the number of points to be examined and their distance from the chimney edge. The calculation program, according to UNICHIM indications, is applied both to circular ducts and rectangular ones.

Definition of emission general parameters
In this menu, the operator sets the peculiar characteristics of the smoke (density, mole fraction of water vapour and so on.) as well as the Darcy constant used and mediation time of the acquired data.

Recording of leak test
The operator can perform a leak test on his complete sampling line for a variable period till 5 minutes, as required by UNI EN 16911. The obtained data can be memorised and downloaded to PC for printing.

Definition of average speed
With this subprogram the operator can measure the speed by placing the Darcy pipe at points of interest and displaying on the screen all the main parameters (ΔP, fumes and ambient temperature, speed etc.). At the end of the acquisition time it is also recorded the average speed for every single point as well as the overall average speed. 
In the speed determination is also taken into account the wall effect and the Swirl’s angle, as required by the UNI EN 16911.
Therefore it is possible to define precisely the profile of the speed in the conduit, an indispensable condition to perform a good isokinetic sampling and characterize the emission.

Definition of the nozzle diameter
This submenu provides a visual summary of the average values of the measured quantities and allows to obtain the calculation of the ideal nozzle diameter.
It is also possible, from a known available diameter, to obtain the calculation of the relative isokinetic flow.

Calculation and display of the isokinetic flow 
On this page the user sees the most important information: the isokinetic flow rate to be set on the sampler. By activating this program on the screen all the most important parameters for the isokinetic sampling are displayed including, of course, the flow rate in litres per minute calculated according to the parameters measured directly by ISOBOOK α  and updated with the frequency set by the operator. The user can run the sampling in perfect s isokinetism  just by adjusting on his own sampler the flow rate shown by  ISOBOOK   α   and the providing adjustments by following computer directions. The use of a microprocessor is essential especially for storage capacity and management: it is in fact possible to store up to 60 measurements, thus preserving the averages of all the parameters that are fully catalogued on the display with the date and time of the event and number of processed area. All data can then be printed, included in a  report, downloaded on any computer  IBM compatible and recalled at any time. ISOBOOK   α   can be powered by network (with an adapter) or battery; this feature – in addition to the small size and low weight – makes it easily to be used in any situation.

The  probe, protected by utility model, through a particular removable insert positioned within the sampling chamber, allows the operator to interchange the sampling media easily (filter – thimble – basket) without removing the probe from its holder in the chimney.

In the rear closing cap of the sampling chamber, always made of titanium, are located the housing of the thermocouple, the hose connection fitting for dust sampling and other three connections that, when not in use, are closed by removable plugs and replaceable with titanium hose.

The probe is heated by resistors connected to a temperature control framework with IP microprocessor 65. The set temperature adjustment is ensured by the thermocouple within the sampling chamber and connected to the temperature control framework.

For the leak test, which must be carried out before each sampling, you should use the blind nozzle (supplied) by screwing it on the terminal part of the curve.

After sampling, and extracting the insert with the sampling device, the operator can clean the probe for retrieving micropollutants still inside it, by closing both the sampling chamber (using the special blind plate supplied ) and the curve nozzle holder, as already described.

The probe is supplied with:

• Sampling room in titanium, provided with a jack for connection to the control unit, equipped with an external jacket in stainless steel AISI 316: between the external jacket and the sampling chamber is located wrapped resistance heating.
