22 FT5 - OPERATION
Measuring Funnel Viscosity
Fluid thickness is called viscosity. The higher the viscosity, the
harder the fluid is to push through the system.
To determine viscosity, you will need a viscosity funnel and a
measuring cup, available from your Ditch Witch dealer.
1. Take a fresh sample from
the drilling fluid tank. The
sample must be more than 1
qt (.95 L).
2. Hold funnel over 1-qt (.95-L)
measuring cup and place a
finger over the outlet.
3. Pour test sample into top of
funnel. Fill to screen.
4. Remove finger and time
flow. Count the number of seconds it takes for 1 qt (.95 L) of
liquid to pass through the funnel. The number of seconds is
the viscosity.
See your Ditch Witch dealer for information on matching viscosity
to soil type.
