Dwyer Instruments CAM Series Operating Instructions Manual

The Series CAM Compressed Air Meter operates by the calorimetric
measuring principle to detect the standard volume flow of operating
compressed air. It is designed specifically to evaluate the current flow
rate and the current consumed quantity in compressed air systems. With
an easily programmable digital display, this unit offers a quick, accurate
readout. The Series CAM is constructed of high-grade materials and is
virtually maintenance free.
Read the product description before installing the unit, to ensure that the
product is suitable for your application without any restrictions. Suitably
qualified personnel must perform work on compressed air equipment.
Ensure that the installation is at a standstill, before mounting compo-
nents into or removing them from compressed air equipment. Ensure
that neither people nor objects are endangered by moving parts before
commissioning / restart of the installation. Non-adherence to the operat-
ing instructions or technical data can lead to personal injury and/or dam-
age to property. In all applications, check compliance of the product
materials with the media to be measured.
