   The portable gravimetric dust meters, type EMIOTEST^R, manufactured by our Company have been gradually supplied to:

• starting from 1991, all regional units of the State Environmental Protection Inspection in Poland,
• environment protection services in big industrial sites, mainly power stations, heat & power generating plants, chemical works, cement factories and steel works, as well as private laboratoriEMIO Innovation & Implementation Firmes.

   In total, there are over 200 sets of dust meters manufactured by us operating in Poland. One particular feature of our Company is high creative and manufacturing flexibility. Equipment and programme solutions enable quick adaptation to requirements and needs of the user. In a number of cases, these requirements are a source of ideas for new solutions.
   All dust meters from the EMIOTEST^R series being used meet requirements of PN-Z-04030-7, and the form of editing final results - i.e. dust concentration, gas stream volume and bulk dust stream - is consistent with GIOS requirements with respect to form of documentation from control measurements. The most modern model of automatic dust meter, EMIOTEST^R 2598, being offered additionally meets requirements included in the ISOICD 12141.2 standard concerning measurements of low dust concentration using the gravity method.

1. Range of application of the dust meter EMIOTEST^R 2598

   The automatic dust meter EMIOTEST^R 2598 is a portable device designed to make measurements of dust concentration in gases (e.g. in waste gases) in the closed ducts as well as to determine the stream of dust mass, e.g. dust emission. The measurement is based on a method of isokinetic aspiration of partial stream of the tested gas and separation from it solid particles on a filter. Isokinetic aspiration relies on gas suction with the velocity equal to the local gas velocity in the main tested stream. It allows to assume, that the dust concentration in the main stream in the duct and in the partial sucked stream are the same. This way of measurement is called a gravimetric method, as the dust stopped in the filter is laboratory weighed after the measurement. Numerous accessories of the dust meter set allows also to measure independently the local gas velocities in the tested duct and the degree of gas moisture content.

    Technical solution of the devices, the operating algorithm of the dust meter and the calculations agree with valid norms ISO 9096 and ISO/CD 12141.2, which concerns the dust concentration measurement below 20 mg/m³.

Functions and outfit of the dust meter allow its wide applications. It is possible to use it especially to :

• make periodical, control measurements of dust emission to the atmosphere
• measure dust concentration in the gas
• test the efficiency of operation of dedusting equipment
• measure gas volume flow rate
• make pre-planned and calibration measurements of devices for continuous measurement of dust concentration and gas volume flow rate
• take representative sample of dust from the dusted gas in order to determine physicochemical properties
• take the sample of the combustion gases in order to determine contents of the dioxins, heavy metals and WWA
• measure dust concentration, air flow rate and degree of its humidity in ventilation and air-conditioning systems and in all the places, where there is a need to make such a measurement.

   Among the users of the dust meter EMIOTEST^R 2598 are especially pollution control civil services and measurement services of industrial enterprises such as: power stations, heat and power generating plants, smelting works, cement plants, chemical factories and other.

2. Structure and functioning of the dust meter

   The dust meter EMIOTEST^R 2598 is a set of devices and accessories configured according to individual needs of the user. It consists of the following elements :

• Segmented or one-parted velocity (integrated with gas velocity measurement system) probe aspiration (1) with exchangeable heads depending on the structure of measuring stub pipes and applied way of dust filtration and exchangeable aspiration tips (2)
• Dust separators used during the internal (2a,2b,2c) and external (2d) filtration (directly in the duct or on external part of aspiration line)
• Three-chamber moisture separator (3)
• Hygrometer module (4)
• Control unit of the set (5)
• Control valve module with the servomotor of the automatic control (6)
• High-efficiency sucking aggregate (8) with the surge vessel (7)
• Temperature probe (9)

Measurement layout of the gravimetrical dust meter EMIOTEST^R 2598

   Central control unit is a specialized industrial computer built in a dustproof shield type "alu-box". The user contacts with the dust meter system using a keyboard and an alphanumeric display. Developed software servicing a dust meter allows :

• easy preparation of measurement set (test of measuring channels, introducting "stable" values, automatic selection of the aspiration tip, procedure of control concerning aspiration line leakproofness etc.)
• automatic control of exceeding established levels of values of selected quantities in order to avoid measurement errors
• checking all the measurement parameters during aspiration, measurement of flow intensity, measurement of gas humidity
• automatic regulation to process of gas suction - visualization of operating trend
• calculating and transforming the results on a printer, a computer or a display in a form of report.

   The dust meter during the aspiration constantly measures and registers 10 quantities representing pressures and temperatures, relative humidity and aspiration time. Values of these quantities are used in current calculating of isokinetic process gas suction parameters and resultive calculating of dust concentration and stream of dust mass. While measuring a dust meter passes to the operator the information about the measurement process, its possible abnormalities and warnings, that such abnormalities may occur. Information is passed in a form of screen messages and acoustic signalling. After measuring there is a possibility to check received results on a screen and also on a thermal mini-printer. Sucking aggregate, which is in a set, with a high ram effect, makes it possible to conduct gas aspiration using long tubing (up to 30 m) allowing easy location of particular elements of the set, such as probe in the measuring stub pipe and control unit together with aggregate on a ground level or in a shielded place.
