F INSTALLATION
FOREWORD
K900 has a 3 inch inlet and outlet. It was designed for permanent installa-
tion on a distribution line and to this purpose, the measurement chamber is
fitted with a threaded inlet and outlet.
The two cables (each one consisting of two wires) sticking out from the
cover of the measurement chamber are to be connected to K900 remote
display.
WARNING K900 does not have a fixed direction of flow and both inlets can be used
as inlet and outlet. It is the filter position which determines the inlet di-
rection of the fluid.
Make sure a filter with adequate filtering capacity is always fitted either
at meter inlet or at the entrance of the line on which the meter is fitted.
If solid particles enter the measurement chamber, the gears could seize.
On installations, place the meter in a position that will enable an easy
access to the batteries compartment
