Working principle
Series AD-15, ADI-15, ADT-15
If a fluid flows with enough flow rate through a metering
pipe A, with a mobile disc B and a calibrated spring C,
the disc will be displaced.
The distance depends on:
−
The flow rate F.
−
The relation between the areas A and B.
−
The opposing force of the calibrated spring C.
−
The equilibrium of the forces defines the position of
the calibrated disc B, and at the same time, the flow
rate.
The calibrated disc B has a magnet M. The magnetic
field acts on the alarms, the indicator or the transmitter.
A = Metering tube
B = Calibrated metering disc
C = Calibrated spring
F = Flow rate
M = Magnet
