The DryCal ® DC-1 and DC-2 primary
flow meters are the original low cost
primary air-flow calibration standards from
BIOS International, the world leader in dry
piston technology. The DryCal
® brings the
advantages of high speed volumetric
calibrations and unsurpassed accuracy to
your organization in a small easy to use
instrument. Its simple push-button
operation has made DryCal
® the preferred
primary flow meter of industrial hygienists,
environmental scientists and calibration
laboratories worldwide.
The DC-1 offers a two line LCD
display providing continuous readouts of
flow rate, flow average, and the number of
readings included in the average. In
addition, the DC-1 is equipped with a built-
in parallel port that interfaces with most
standard IBM compatible printers to obtain
hard copy documentation of flow rate data.
The DC-2 offers all the features of the
DC-1, but adds several other important
features, including atmospheric pressure and
user definable temperature corrections
based on built-in precision sensors. These
corrections result in readings equivalent to
those at standard condition. This feature is
especially useful with mass flow devices.
The standardized readings are displayed
simultaneously with the volumetric readings
on a larger four line LCD display. The DC-2
also allows users to define the number of
readings in the flow average from 1 to 100
measurements and includes an RS-232
interface for direct download to a PC for
easy audit tracking.
Both the DC-1 and DC-2 share three
interchangeable flow measuring cells,
providing by far the broadest dynamic
range in the industry from 1 ml to 50,000
ml per minute. All DryCal
® flow cells use
the same near-frictionless piston and photo-
optic sensing technology to obtain
volumetric flow readings quickly and
accurately.
