AVL Smoke Meter

Reliable and robust measuring equipment

A filter-type smoke meter for the measurement of soot content. 

AVL Smoke Meter

The AVL Smoke Meter is designed to automatically measure soot content in the exhaust gas of combustion engines. The device meets the requirements of ISO 10054 as well as ISO 8178-3 and can be used in a variety of applications.

Increasingly stringent emission regulations for combustion engines are the main reason for the push towards high-performance emission measurement tools, which also gives rise to new challenges.

Some applications, such as durability tests, require reliable and robust measuring equipment. Others require high accuracy and a very low detection limit, such as engines with diesel particulate filter systems (DPF) that emit very little soot. Moreover, OEMs are looking to keep the total cost of ownership (TCO) of their measuring equipment as low as possible. We have developed the AVL Smoke Meter to meet all of these requirements.

Smoke Meter

How Does it Work?

The AVL Smoke Meter uses the filter paper method to determine filter smoke number (FSN defined according to ISO 10054) and soot concentration in mg/m3. The variable sampling volume and thermal conditioning of the exhaust gas ensures an extremely high reproducibility and a wide range of applications. This innovative tool can measure emissions in both large/heavy-duty engines as well as in smaller engines installed in passenger cars.
The main areas of application are for combustion optimization of prototype engines and emission monitoring up to the start of series production and thereafter. In addition, the instrument can perform soot or black carbon mass concentration measurements in raw exhaust gas (e.g. upstream of a DPF) in line with ISO 8178-3 standards. With its easy integration into an automation system and remote maintenance options, the AVL Smoke Meter reduces operating costs, service times and training periods.

Technical Data  

Measurement principle

Filter paper blackening
Measured value output FSN (filter smoke number),
mg/m³ (soot concentration)
Measurement range 0 to 10 FSN
Detection limit 0.002 FSN or 0.02 mg/m³

 

Smoke Meter
Highest Reproducibility 

The variable sampling volume, thermal conditioning of the exhaust gas and purging with compressed air ensures a high reproducibility of measured values and reduces hang-up effects.

Altitude Simulation and Measurements 

The AVL Smoke Meter also enables altitude simulation using low pressure in the exhaust gas system and measurements up to 5,000 m above sea level. 

Operation and Automation 

Easy integration into automation systems, short training periods thanks to its intuitive operation and remote maintenance options result in low total cost of ownership (TCO).

Remaining Paper Indicator for Seamless Operation

The AVL Smoke Meter has a remaining filter paper indicator on the front of the housing. The light-emitting diodes indicate when the paper supply is low. This makes it easier for you to know when to replace the paper roll, for example, before a durability test. 

Shop Air Purging

The AVL Smoke Meter can be equipped with a shop air purge option. The higher pressure compared to purging with the diaphragm pump has the key advantage of reducing particulate deposits in the device and in the sample lines.

Measurements of High and Low Soot Concentrations

Diesel particulate filters (DPF) are commonly used in modern engines. To determine their efficiency or detect any malfunctions, exhaust gas is sampled upstream and downstream of the DPF. Only one AVL Smoke Meter is needed to perform this measurement task. The use of two sample lines makes it possible to switch between two different sampling points.
