Type 8026- 8036- 8076 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.
Type 8026- 8036- 8076 Description 5.2.2. Construction of the 8036 The 8036 flowmeter comprises: A: an S030 fitting including the paddle-wheel flow sensor. C B 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.
