Pressure loss
No pressure loss if the sensor is installed in a pipe of the same nominal diameter.
Pressure losses occur in configurations incorporating adapters (reducers, expand-
ers). Contact your Hauser representative or Hauser for informa-
tion.
Flow limit
As a rule, the pipeline diameter determines the sensor diameter. With a known
flowrate and the help of the Hauser Flow Applicator, the best size can be
selected. Generally, a velocity range of 6 to 10 ft/sec should be selected.
A necessary increase in velocity can be achieved through a reduction of the sensor
diameter. The higher installation expense is normally balanced by the lower sensor
cost.
The flow velocity should also be determined by the fluid’s physical properties:
•
v < 6 ft/sec, for abrasive mediums such as potter’s clay, lime milk, ore slurry, etc.
•
v > 6 ft/sec, for fluids causing build-up such as wastewater sludge, etc.
