1 Product Description
The pulse adapter CPA 01 consists of a battery pow-
ered electronics assembly in a polymer housing. The
housing is potted and therewith water tight. The
pulses are provided to the connected electronics via
cable.
2 Use
The pulse adapter converts the volume information
from the Cordonel flow meter into volume propor-
tional pulses. Typical applications are:
• Controlling processes of systems with pulse input
• Transmission of pulses for the remote display of
the meter index
• Transmission of pulses for detailed data analysis
with an external data logger

5.1 Safety Information
The installation site of the CPA 01 must be clean
and dry. Dirt and humidity can impede a fault free
pulse transmission. The electrical connection must

connection can lead to injury or death resp. can
damage the CPA 01.
5.2 General Information
The CPA 01 has a strain relieve which can absorb
up to 50 N.
5.3 Required Tools
For opening the pulse adapter cover at the Cordonel
a screw driver with a blade size 5 mm or any other
suitable lever tool is required.
5.4 Orientations
The orientation of the CPA 01 is provided by the ori-
entation requirements of the Cordonel flow meter.
5.5 Installation Advice
Clean the Cordonel flow meter in the area of the
cover for the pulse adapter CPA 01. Open the cover
1
for the CPA 01 and keep it safely. Remove the
blind plug from the Cordonel flow meter. Check the
correct fit of the O-ring at the CPA 01. Insert the CPA
01 with the round side ahead into the interface of the
Cordonel flow meter. Close the interface with the
cover by clicking it in. If necessary seal the cover
with an appropriate wire seal (wire-Ø < 1,9 mm).
