4.4. Installation of the SI5004 flow sensor
The SI5004 flow sensor is a calorimetric detector that converts its response in a 4/20 mA analog signal. The output signal corresponds to the
curve of the sensor. Led bar located in the head indicates the relative flow velocity in the range of detection. When there is no flow through it,
the led "0" flashes. The SI5004 sensor comes factory calibrated (5 ... 100 cm/s) in water, so it is not necessary to make any recalibration
process at installation time. The sensor response time can vary in the range 1 ... 10 seconds.
Screw the E40096 thread adapter supplied on the position labelled "FLOW" at the body of the UV reactor. Then screw the SI5504 flow sensor
on the adapter.
Connect the SI5004 sensor with the EVC005 cable supplied with the unit to the corresponding terminals at the terminal block inside the control
box.
