Inspect the EGR delivery pipe delta P pressure ports for blockage. If excessive build up or blockage is found, clean the venturi pipe and reinstall the sensor, Go to step 24. If no damage is found, Go to step 7. Remove EGR cooler hot pipe, EGR crossover tube and mixer pipe and inspect for excessive build up or blockage. Addictive drums library location. After EGR cooler outlet pipe has soaked for at least 15 minutes, clean the pipe using EGR cleaning fluid and a flexible 2” round brush inside a bucket or waste container. Fluid can be saved to be used on other EGR components if required. Remove adapters and reassemble vehicle components in the reverse order of removal.
Ventury flow meter works on the principle of Ventury Effect. A reduction in fluid pressure occurs when a fluid flows through a constricted section of pipe. This happens mainly due to increased flow velocity because of reduced cross section.

This workshop manual contains detailed inspection, testing, adjusting, disassembly/assembly and removal/installation procedures for the Detroit Diesel DD13, DD15. The Venturi effect is the reduction in fluid pressure that results when a fluid flows through a constricted section (or choke) of a pipe. The Venturi effect is named after its discoverer, Giovanni Battista Venturi Background. In inviscid fluid dynamics, an incompressible fluid's velocity must increase as it passes.

Venturi Flow Meter Installation
Reduction in pressure is related to actual fluid velocity as well as density of the fluid. Pressure is measured at normal cross section as well as constricted cross section, to get the differential pressure. Based on this differential pressure, fluid velocity and hence volumetric flow rate can be determined.
Ventury Flow MeterStraight Length Requirements
Terminology
Diameter (D) = nominal Pipe Size
Example:
Venturi Pipe Design
13 Diameters of 6″ pipe = 78″
13 Diameters of 10″ pipe = 130″ Total war 2.
Beta = (Bore I.D./Pipe I.D.)
Bore is the smallest diameter of an orifice or nozzle
Up = Upstream Diameters
Down = Downstream Diameters
Two Elbows, > 10 Diameters, Fittings in Different Planes
When Beta is both 0.5 or 0.7 , upstream straight lenght shall be minimum 21D and downstream straight length shall be minimum 2D.
Two Elbows, < 10 Diameters, Fittings in Different Planes
When Beta is both 0.5 or 0.7 , upstream straight lenght shall be minimum 21D and downstream straight length shall be minimum 2D. Help with updating affinity designer.
Reducer or Expander (Unless Another Upstream fitting Needs More)
If upstream has a reducer, then if Beta is 0.5, upstream straight length shall be minimum 5D and downstream shall be minimum 2D. Also in this case if Beta is 0.7, upstream straight length shall be minimum 8D and downstream shall be minimum 4D.
Venturi Pipe Fittings
If upstream has an expander, then if Beta is 0.5, upstream straight length shall be minimum 2D and downstream shall be minimum 2D. Also in this case if Beta is 0.7, upstream straight length shall be minimum 4D and downstream shall be minimum 4D.
