Production Description LZS preservative pipeline type PVC plastic float Liquid air
rotameter
The plastic rotor flowmeter falls under the category of rotor (or
float) flowmeters. It features a cone tube made of AS plastic, a
takeover (flange) nut, upper and lower stops made of UPVC, and a
float made of ABS plastic. There are two variations available:
LZS-D, which is a short tube type, and LZS-L, which is a long tube
type. This flowmeter is primarily used in sewage treatment and
environmental protection projects to measure the non-pulsating flow
of single-phase liquids.
The key components of the LZS series plastic rotor flowmeter,
including the cones, are constructed using AS and ABS plastics.
These materials offer excellent corrosion resistance,
affordability, reasonable structure, compact size, lightweight, and
enhanced durability, as the cones are less prone to breakage. As a
result, the plastic rotor flowmeter finds wide applications in the
chemical, environmental protection, food, and other industrial
sectors.
The flowmeter offers multiple connection methods, including
plug-in, welding, threaded, and flange connections. This
flexibility allows for easy installation and integration into
existing systems, catering to different operational requirements
and preferences.
The plastic tube flowmeter possesses several notable features, such
as high transparency, providing clear and intuitive readings;
resistance to breakage; lightweight construction; long service
life; and convenient installation and connection. These
characteristics make it a reliable and user-friendly choice for
flow measurement applications.

Structure and principle of LZS plastic flowmeter
It is mainly composed of a transparent plastic cone tube with the
small end down and the big end up, and a float that can move up and
down in the cone tube as a measuring element, and is composed of
nuts, nozzles, stoppers and "O" rings. When the fluid flows from
bottom to top in the conical tube, a pressure difference is
generated up and down the float, which makes the float rise. When
the pressure difference is in force balance with the gravity,
buoyancy and viscous force of the float, the float is in a static
position. When the flow rate changes, The flow velocity of the
fluid flowing through the annular gap between the cone tube and the
float changes, the pressure difference between the upper and lower
floats changes accordingly, and the float moves up and down, so the
height of the float at the static position can be used as a measure
of flow.
