Description
5. DescripTion
5.1. Area of application
8026, 8036 and 8076 devices are intended to measure the flow rate of liquids:
• 8026 and 8036 flowmeters are used to measure the flow of neutral or slightly aggressive liquids,
• 8076 flowmeters are used to measure the flow rate of viscous liquids such as honey or oil, which are free of
solid particles.
Thanks to one or two fully adjustable transistor outputs, the device can be used to switch a solenoid valve,
activate an alarm and, thanks to one or two 4-20-mA current outputs, establish one or two control loops.
5.2. General description
5.2.1. construction of the 8026
The 8026 flowmeter comprises:
A
B
C
A: a paddle-wheel flow sensor, the rotation of which generates pulses.
Set in rotation by the flow, the 4 permanent magnets integrated in the vanes of the
paddle generate pulses, the frequency of which is proportional to the flow speed of
the fluid. A conversion coefficient specific to each pipe (material and diameter) is
necessary to establish the flow rate value associated with the measurement.
The conversion coefficient (Factor K) expressed in pulses per litre is given in the user
manual for the fitting used.
B: an acquisition / conversion module for the process values measured:
• acquisition of the pulse frequency
• conversion of the frequency measured into flow rate units
C: a display module with navigation button used to read and/or configure the para-
meters of the device. The display module is not delivered with all the versions of the
flowmeter but it is available as an accessory.
