INSTALLATION
Basic Installation Instructions
The meters are mounted in-line and are direct reading. The meters
can be mounted in a vertical or horizontal position as long as the fluid
is flowing in the direction of the arrow on the flow scale. No straight
pipe is required before or after the meter. In fact, 90° elbows can be
installed on both ends without any noticeable flow variation.
When installing a meter, apply “Thread seal Tape” or “Liquid Thread
Sealant” on pipe threads. If tape is used, be sure to leave 1/8" (3 mm)
of pipe thread exposed on end of pipe. Position filter in front of meter
and in a location that allows easy access for routine maintenance.
Refer to “Warnings and Precautionary Areas” for additional informa-
tion.
INSTALLATION DOS AND DON'T
To obtain satisfactory operation from a Lake flow meter, the following
points should be considered:
DO:
install a pressure gauge near the inlet of the meter
place throttling valves at the outlet of the meter
use pipe sealer on the connections
install a union on one side of the meter for easy removal for
maintenance and calibration
install solenoid valves at meter outlet (as far downstream as possible)
mount in any orientation: vertical, horizontal or upside down
DO NOT:
place restrictions between the meter’s pressure gauge meter inlet
use in systems where reverse flow is possible
place meter in non-aligned piping
over-flow the meter by more than 150% of maximum reading
operate at pressures and temperatures greater than specified
*install restrictions between pressure gauges and the meter inlet
*install solenoid valves at the meter inlet
*pneumatic flow meter applications
