Lake Monitors Case Drain Monitor - Manual (Page 3)

Basic Application Information
The flow meter can be installed directly in the fluid line without flow
straighteners or special piping. The meter is used to measure the flow
rate of most liquids which do not contain particles greater than 74 micron.
1) External components are sealed inside the Lexan window tube to
permit use in areas where the meter may be sprayed or washed
with soap and water.
2) Mount the meter in the most convenient location to allow easy
access for reading and maintenance.
3) The meter should NOT be mounted near hot pipes or equipment
which can cause deformation of the window tube and scale.
4) The meter should be mounted at least one foot (.3 meter) from
large electric motors, or the internal magnet may weaken or
become demagnetized.
5) Aluminum and brass meters should not be mounted where
assembled piping is not supported.
