■ Cautions for Installation
Mounting Positions
Avoid all pipe locations where the flow is pulsating, such as in the outlet side of piston or diaphragm pumps.
Avoid locations near equipment producing electrical interference such as electric motors, transformers, variable frequency, etc.
Install the meter with enough room for future access for maintenance purposes.
Warning: Precaution for direct sunshine and rain when the meter is installed outside.

Turbine Flow Meter
Required Lengths of Straight Runs
Flow altering device such as elbows, valves and reducers can affect accuracy. See diagram below for typical flow meter system installation.
Diagram 1. Typical Flow Meter System Installation
The recommended guidelines are given to enhance accuracy and maximize performance. Distance given here are minimum requirements; double them for desired straight pipe lengths.
◾ Upstream: allow a minimum straight pipe length at least 10 times the internal diameter of the pipe. For example, with the 50mmpipe, there should be 500mm of straight pipe immediately upstream. Desired upstream straight pipe length is 1000mm.
◾ Downstream: allow a minimum straight pipe length at least 5 times the internal diameter of the pipe. For example, with the 50mm pipe, there should be 250mm of straight pipe immediately upstream. Desired upstream straight pipe length is 500mm.

Turbine Flow Meter
Special Notice
♦
Foreign material in the liquid being measured can clog the meter’s rotor and adversely affect accuracy. If this problem is anticipated or experienced, install screens to filter impurities from incoming liquids.
♦
To ensure accurate measurement, drain all air from the system before use.
♦
When the meter contains removable coverplates. Leave the coverplate installed unless accessory modules specify removal. Don’t remove the coverplates when the meter is powered, or electrical shock and explosion hazard can be caused.
