Description of the unit
The Calor 40 is a flow meter based on the measuring principle of Faraday’s electromagnetic
induction law, according to which a voltage is induced when a conductive fluid flows through
the magnetic field of the flow meter. This voltage is picked up with two electrodes that are in
direct contact with the liquid measured and it is evaluated in the electronic unit.
The inductive meter Calor 40 is suitable exclusively for measuring volumetric flow of
conductive liquids with a minimum conductivity of 2 S/cm.
The meters are designed for flow measuring where the speed of liquid is within the range
0.01 ÷ 10 m/s. The greatest accuracy of measurement is reached within the range 1 ÷ 10 m/s.
The special version of CALOR 40 provides for measurement of heat delivered by the ethylene
glycol-water mixture. For correct measurement, the correct mixture rate must be set up in the
meter. Incorrect setting or using other medium than it is presented in the chart below may
result in incorrect measurement.
