Figure 1 below shows the relationship between these three variables. As airflow increases, the differential pressure drop across a filter will increase proportionally to the flow rate squared. As the ...

Nevertheless, these rates can differ greatly with changes in pressure and/or temperature. The volumetric flow rate of the fluid can be determined by measuring the differential pressure across a ...

The “Ideal” line in figure 1 illustrates this point, showing how liquid flow rises linearly when charted against the square root of the differential pressure across the valve divided by specific ...

The pressure/flow relationship depends on the length and condition of the reference piping, pressure tap locations, and the geometry of the restricting element (differential producer). Any change ...

The DPTW series can also be used to measure hydrostatic liquid level in pressurized or open tanks and flow measurement using primary differential pressure flow elements such as an annular pitot tube, ...

Designed primarily for use in the oil and gas industry, differential pressure recorders are also suitable for monitoring flow, filtration, and liquid levels. Differential pressure ranges from 20 to ...
