DN15-DN100 Mechanical Indicator Steam Metal Tube Rotameter Variable
Area Sewage Chlorine Oxygen Nitrogen Gas
Description
This product uses a metal tube float or glass rotor flowmeter and a
constant flow valve to form a flow purge device to achieve flow
measurement and ensure constant flow output. Due to the safety and
reliability of the float flowmeter and the characteristics of
accurate and stable measurement, this series of air blowing devices
can ensure constant flow output when the inlet or outlet pressure
changes. It can be widely used in petroleum refining, chemical
industry, ethylene, fertilizer, steel, etc. In the process control
of transmitters in chemical fiber, textile and other industries
such as purging and differential pressure liquid level measurement.
The design structure of this series of products fully meets the
requirements of industrial control, and the applicable installation
conditions fully comply with the requirements of instrument
measurement technology.
Typical applications under conditions of changing gas supply
pressure are shown on the right: the gas provided by the main
pipeline gas source can be divided into multiple branches as
needed. If the gas flow of several branches is closed or adjusted,
it will cause When the air supply pressure of the main pipeline
changes, the single-channel purging device installed on the support
can accurately measure the flow rate.
Please choose a suitable location to install the flow purge device
to ensure that the flow meter purge device is easy to debug, clean
and disassemble. When installing, make sure the flow direction of
the medium is the same as the direction required by the flow purge
device, and close all the fine-tuning needle valves. Before putting
into operation, please empty and purge the pipeline to avoid
impact. The valve should be opened slowly to adjust to the working
pressure, and the flow rate should be changed by adjusting the
opening of the valve to prevent the float from being impacted,
thereby damaging the measuring components.

Installation Precautions
Please choose a suitable location to install the flow purge device
to ensure that the flow meter purge device is easy to debug, clean
and disassemble. Since the purge device float flowmeter is equipped
with a collision transfer system, it is necessary to ensure that
the interference field generated by other working equipment does
not affect the measurement results of the flowmeter. When
installing, ensure that the flow purge device is stable and add
Fixed bracket. The installation dimensions should not exceed the
given dimensions by too much or too little to avoid tensile and
compressive forces acting on the purge device. When the liquid
medium contains ferromagnetic particles, a
Be sure to expose any colliding particles in front of the
instrument. Be sure to ensure that the flow direction of the medium
is the same as the direction required by the flow purge device.
When installing the instrument, close all the fine-tuning needle
valves.
close. Before putting into operation, please empty and purge the
pipeline to avoid impact. The valve should be opened slowly to
adjust to the working pressure. The flow rate should be changed by
adjusting the opening of the valve to prevent the float from being
impacted and thereby damaging the measuring components.
