The V40 is a measuring instrument with for detecting
the flow of water or water/glycol mixtures and is used
in combination with the calorimeter integrated into the
Multi. After a specific volume has passed the V40 reed
switch sends an impulse to the calorimeter.The heat
quantity used is calculated by the calorimeter using
these impulses and the measured temperature diffe-
rence with the help of pre-defined parameters (glycol
type, concentration, heat capacity, etc.).

Precision-platin sensors PT1000 are used for the con-
troller COSMO Multi.
Depending on the individual solar system, the product
range contains 3 different sensor types: sensors with
immersion sleeves, flatscrew sensors and cylindrical
clip-on sensors.
