Coal Seam Borehole Gas Flow Meter

Coal Seam Borehole Gas Flow Meter is primarily used for measuring the natural gas flow rate in coal seam boreholes in underground coal mines or the initial gas velocity q value during outburst prevention tests. It can also be used for measuring the flow rate (velocity) of other gases. The borehole gas flow meter features automatic display, storage, timing, time-sharing, and continuous cumulative flow (velocity) functions. With its compact size, lightweight design, and ease of operation, the DMF borehole gas flow meter is suitable for use in explosive gas environments in underground coal mines. It is also applicable for measuring gas flow (velocity) in laboratories or other settings.
