Monitor the nitrogen flow measurement flowmeter to report

[ Focus on Chemical Machinery Equipment Network ] Metering is the eye of industrial production.
The development of flow measurement can be traced back to ancient water conservancy projects and urban water supply systems.

 

Flowmeter quantity measurement is an integral part of science and technology, and its national economy, national defense, scientific research are closely related.
Doing this well will play an important role in ensuring product quality, improving production efficiency, and promoting the development of science and technology.
Especially in the current era of energy crisis and increasing automation of industrial production, flow meters are in the national economy.
The status and role of the company are more obvious.

 

In addition, in the industrial field, the instruments that measure fluid flow are collectively referred to as flow meters or flow meters.
It is one of the most important instruments in industrial measurement.
With the development of industry, the requirements for the accuracy and scope of flow measurement are getting higher and higher.
In order to adapt to a variety of purposes, various types of flow meters have come out, which are widely used in oil and gas, petrochemical, water treatment, food and beverage, Pharmaceutical, energy, metallurgy, pulp and paper and building materials industries; it has obvious high measurement accuracy, reliable display data, earthquake resistance and interference resistance that other flow meters do not have, and it is suitable for monitoring various gas conditions.
Let me know with you what kind of flow meters are used to monitor nitrogen flow measurement, right?
 

It is understood that there are three commonly used flow meters for measuring nitrogen, precession vortex flowmeter, gas vortex flowmeter, thermal gas mass flowmeter.
When selecting the model, it is necessary to select the appropriate one according to the parameters and cost that can be provided on site.
Model specifications.

 

The precession vortex flowmeter can be widely used in petroleum, chemical, electric power, metallurgy, urban gas supply and other industries to measure various gas flows.
It is currently a common product for oilfield and urban natural gas transmission and distribution measurement and trade measurement.
Because of the precession vortex flowmeter Because of its uniqueness, it must constantly adapt to the development of the level of mechanical manufacturing during its development.
Therefore, the precession vortex flowmeter is divided into "intelligent precession vortex flowmeter" and "steam precession vortex flowmeter" according to the different measurement objects.
Vortex flowmeter".

 

Vortex flowmeters are more common, and they are mainly used for flow measurement of industrial pipeline fluids, such as gases, liquids, vapors and other media.
It is characterized by small pressure loss, large range and high accuracy.
It is hardly affected by fluid density, pressure, temperature, viscosity and other parameters when measuring volume flow under working conditions.
Therefore, gas turbine flowmeters are optional for measuring nitrogen.

 

Thermal gas mass flow meter is an instrument that uses the principle of thermal diffusion to measure gas flow.
The sensor is composed of two reference thermal resistance (RTD).
One is the speed sensor RH, and the other is the temperature sensor RMG that measures the temperature change of the gas.
When the two RTDs are placed in the measured gas, the sensor RH is heated, and the other sensor RMG is used to sense the temperature of the measured gas.
As the gas flow rate increases, the gas flow takes away more heat, and the temperature of the sensor RH decreases.
