FLOW DIRECTION
STRAIGHT RUN REQUIREMENTS FOR INSERTION TURBINE FLOW METERS
Series F-1100 Single Turbine Flow Meters
GENERAL PRACTICES
1. For best results, install the ow meter in a straight run of pipe,
free of bends, tees, valves, transitions, and obstructions for a
distance of at least 20 pipe diameters upstream and 5 diameters
downstream.
2. Longer straight runs may be required in applications where the
meter is placed downstream from devices which cause unusual
ow prole disruption or swirl, for example, modulating valves or
two elbows in close proximity and out of plane, etc.
3. If there is not sufcient straight run, allow 80% of the run upstream and
20% of the run downstream. If the total length of straight run is less
than 20 diameters, performance may seriously
degrade, and consideration should be given to
changing to the series F-1200 Dual Turbine
Flow Meter.
FLOW DIRECTION
Minimum upstream
straight run distance
20 pipe diameters from any
valve, elbow, tting, etc.
Minimum downstream
straight run distance
5 pipe diameters to any
valve, elbow, tting, etc.
Series F-1200 Dual Turbine Flow Meters
FLOW DIRECTION
GENERAL PRACTICES
1. For best results, install the ow meter in a straight run of pipe,
free of bends, tees, valves, transitions, and obstructions for a
distance of 10 pipe diameters upstream and 5 diameters
downstream.
2. Longer straight runs may be required in applications where the
meter is placed downstream from devices which cause unusual
ow prole disruption or swirl, for example, modulating valves or
two elbows in close proximity and out of plane, etc.
3. If there is not sufcient straight run, allow 80% of the run upstream and
20% of the run downstream. If the total length of straight run is less
than 70% of recommended distance, performance
may degrade and consideration should be given to
changing to the F-3000 Series Inline
Electromagnetic ow meter.
FLOW DIRECTION
Minimum upstream
straight run distance
10 pipe diameters from any
valve, elbow, tting, etc.
Minimum downstream
straight run distance
5 pipe diameters to any
valve, elbow, tting, etc.
