8.7 Hydraulic accessories
The following chapter is intended to give you an overview of installation
options.
Please note that these operating instructions are no substitute for the
instructions supplied with the accessories in each case. The corre-
sponding documentation supplied with the product applies to safety
information and provides exact instructions on assembly.
8.7.1 FLOWCON LP 1 flow meter
The FLOWCON LP 1 flow meter was specially developed for monitoring
oscillating volume flows. The function is based on the evaluation of the
pulsating dosing quantity that typically occurs in dosing pumps.
During the pressure stroke, a float element is lifted from the flowing
fluid, thus activating a reed switch. By adjusting the switch point, it is
possible to monitor the dosing quantity previously determined by
gauging.
This makes it possible not only to sense whether the dosing pump is
delivering fluid, but also whether the set dosing capacity is achieved.
Assuming equal pressure and viscosity of the medium, reproducibility is
of the order of 10 – 20%.
Notes on assembly:

function, see page 35.
For information on the connection, see “Dosing control input” on
page 30.

8.7.2 Injection nozzle
If the pressure line enters a main line, it is advisable to install an injec-
tion nozzle.
Injection nozzles have three main functions:
Dosing the medium into a main line,
Preventing flowback into the pressure line through a non-return
valve.
Notes on assembly:
Double-ball injection nozzles must be installed into the main line
vertically from the bottom. You can install hose and spring-loaded
injection nozzles any way you like.
With dosing media that tend to crystallize, it is advisable to carry out
installation into the main line from the bottom. This prevents air
bubbles from being trapped.
Many dosing media tend to contaminate the injection nozzles, which
can lead to blockages. In cases like this, it is advisable to install an
injection nozzle that is easy to dismantle and block off.
