4 System description
4.1
Flow cell
The flow cell is the part of the Ultrasonic Flowmeter Series 6 that is mounted in the piping
system. All components making the Ultrasonic Flowmeter Series 6 (SPU, transducers, type
plates and optional pressure and temperature sensors) are mounted on the flow cell, see
Figure 4.

4.2
Signal processing unit
The SPU is mounted in an explosion proof housing. The box consists of two separate
compartments; a main and a rear compartment (see Figure 5).
The main compartment can be opened from the side of the SPU and contains the main
circuit boards. The main compartment also comprises intrinsically safe connections for the
ultrasonic transducers and optional temperature and pressure sensors. All data processing
from excitation of the transducers to calculating the flow rate is handled by the electronics in
this compartment.
To prevent the box from opening by vibration, the covers on the side need to be firmly
tightened and secured with the lock screw in the cover, see Figure 6. When closing the
back compartment ensure all screws are used.
A grounding point is foreseen at the bottom of the SPU. As the meter is already internally
grounding, it is not necessary to use this grounding for normal operation.
