The
Series CP/CN/CT/CX Coolpoint
®
Vortex Shedding Flowmeter
is made for
water, water/glycol mixtures, or low viscosity fluids. These units contain no moving
parts to clog or wear, allowing for minimal maintenance in the field. This series has two
versions: a 3-wire version, where power is supplied separate from the 4-20 mA output,
and a 2-wire loop-powered version. The 3-wire version is equipped with a solid state
relay that can be configured in the field to be either an alarm or a pulse output, an LED
display which allows the user to choose between selectable engineering units (GPM or
LPM), and a high temperature option. The alarm on this version is selectable between
a high or low alarm (NO or NC) and the pulse output option is set at a frequency at a
specific pulses per gallon. The 2-wire option allows for operation in an intrinsically safe
mode only when used in conjunction with an approved intrinsic safety barrier meeting
required entity parameters. This version does not come with a display or relay contacts
to allow for this operation mode.
