Nowadays people are very aware of the need
to protect the environment. They need to reduce energy consumption. This demand
has led to the widespread use of the thermal dispersion flow meters.
Because this kind of gas flow meter can let people know the amount of gas which
is used, and better detect exhaust emissions.
The American government has enacted
regulations requiring gas and oil natural systems to detect carbon dioxide and
greenhouse gas emissions, which has led to the widespread use of gas flow
meters. A large number of petrochemical industries are affected by this policy
and taken actions to detect the exhaust gas flow measurement.
A wide variety of measurement techniques are used in this industry, but the following factors of the gas flowmeter are important.
1. Flowmeter
repeatability
2. Flow
meter measures mass flow
3. Flowmeter
accuracy
4. Flowmeter
range ratio
6. Performance stability of the flow meter
Conventional gas flowmeters measure
volumetric flow, such as gas turbine flowmeters, orficate plate flow meters, vortex
flowmeters, etc. If you want to measure mass flow, you need a temperature
sensor (such as a thermal resistor RTD), a pressure sensor, and a flow
totalizer to achieve temperature and Pressure compensation measurement.
However, the thermal immersible mass flowmeters does not require
additional temperature and pressure compensation, and its measured value is
hardly affected by the pressure and temperature of the medium.
For pipe line diameter is smaller than
100mm, we generally choose a flanged thermal flowmeter. For pipes lines larger
than 100mm, we usually choose a insertion type gas flow sensor. The thermal
mass gas flow meter has no moving parts, and the plug-in process connection
method is more convenient to install and maintains. For gas flow measurement in
large pipelines, the insertion type gas mass flow meter is a very good choice.
The Thermal mass flowmeter has a very wide
measurement range with a turndown ratio of 100:1, and the gas sensor can even
detect extremely low flow rates of gas.
the immersible mass flowmeters
supplied by Silver Automation Instrumentation is equipped with digital display,
button operation and commissioning, 4-20mA output, RS485 communication for
emission monitoring and combustion control. Customers can also have more needs,
such as the need for hart communication, or the digital display can show the gas
medium temperature range, our flowmeter can meet these specifications with extra
cost. The SRK-100 series of mass flow meters provide the petrochemical industry
with a simple, convenient and very cheap way to monitor energy consumption.
In addition, natural gas has enjoyed a
reputation as the cleanest fossil fuel for many years because it emits less
carbon dioxide into the atmosphere than coal or oil. With the advancement of
shale gas technology, domestic natural gas has become richer and cheaper, and
more and more has replaced coal for power generation, as well as replacing
gasoline and diesel as fuel for vehicles. The thermal mass flow meter is a very
good process instrument for measuring natural gas. It is easy to install and
cheap, and is popular among many people.
