The Defender primary flow meter is a field
portable primary flow standard. Uses DryCal near-frictionless
piston technology and photo optic sensing to obtain volumetric
and standardized volumetric flow readings quickly and accurately.
Easy-to-use push button operation has
made DryCal the preferred primary flow system of industrial hygienist,
environmental scientists and calibration laboratories world wide.
