PRODUCT DESCRIPTION

The Beta Gauge F-904 Extractive Beta Gauge Particulate Monitor by VEREWA determines particulate concentration by measuring the amount of radiation a sample absorbs when exposed to a radioactive source. In general, the more energy absorbed, the greater the particulate concentration. The Model F904 is ideal for small diameter stack monitoring and there is a transportable version for mobile applications.

The typical applications that are suitable for the Model F-904 include coal and oil fired power plants, waste incinerators, waste water sludge incinerators, dust monitoring after wet scrubbers and heavy metal analysis. The instrument consists of five main modules. The sample probe in either stainless steel or titanium and these probes are suitable for either direct or diluted sample extraction and are heated. The sample is then passed through a heated sample line and is directed onto a filter tape. Once the gas passes through the filter tape it is routed to a downstream cooler to extract water and ensure a dry sample. A carbon vane rotary pump and mass flow controller ensure that the sample stream is pulled through these components at a flow rate of 3 cubic meters per hour.

The functions of the Model F-904 Extractive Beta Gauge Particulate Monitor are controlled by a powerful on-board microprocessor which calculates the particulate concentration value from the gas volume and zero/final radiation absorption differential.
