What LC Strainers Do
Strainers protect meters from serious damage caused
by burrs dislodged from new piping, pipe scale, or foreign
material.
The strainer’s initial cost is good insurance against the
cost of down time or replacement parts incurred from a
damaged meter.
A meter strainer installed on the inlet side is necessary
even when a coarse strainer on the upstream side of the
pump is included in the system.
Strainers are not meant to be used as a system filter but
as protection for the meter element itself.
How LC Strainers Work
As liquid product enters the strainer housing from the
supply line, it is routed through the strainer basket. The
strainer basket is a two-ply screen. The inner screen is
made of fine mesh of either 20, 40, 80, 100, or 200
squares per inch. The outer screen works as a backing.
It gives reinforcement and support to the fine mesh inner
screen.
Liquid product is filtered and exits the strainer basket
through the screens into the strainer housing. The liquid
then passes through the outlet of the strainer and into
the inlet of the meter. Any debris larger than the mesh in
the basket is trapped.
A properly maintained strainer helps to ensure the system
owner years of trouble free service.
Features
LC markets a wide variety of strainers to fit most meters
in terms of capacity, pipe size, working pressure and
metallurgical compatibility. The design advantages of a
Liquid Controls strainer include:
• Strainer baskets with an unusually high open basket
area to pipe area ratio, resulting in minimum
restriction of flow and low pressure loss.
• A choice of stainless steel strainer basket mesh sizes.
