Small gas flowmeterThe manufacturer of the production quotation for this flowmeter product model belongs toGas flow meterClassification: For more direct sales price quotations of micro, small, and flow control instruments, please feel free to call us for consultation. Below is the product information and details of small gas flow meters.

Small gas flow meters are generally designed for small diameter and small flow environmental conditions. All small gas flow meters generally require higher accuracy. In terms of flow meter selection, small gas flow meters are generally selected as vortex gas flow meters or MF5706 micro gas specific flow meters,Small gas flowmeterCommonly used in hospitals, laboratories, chemical facilities, and other places.

Overview of Small Gas Flowmeters

The vortex flowmeter is developed based on the Karman vortex principle and is a new type of flowmeter with international advanced level. Due to its advantages that other flow meters cannot provide, it has developed rapidly since the 1970s. According to relevant information, the use of vortex flowmeters has sharply increased in developed countries such as Japan, Europe, and America, and has been widely applied in various fields. It will occupy a better position in future flowmeter production and be an ideal substitute for orifice flowmeters. Vortex flowmeter is suitable for measuring the mass flow rate and volume flow rate of superheated steam, saturated steam, compressed air, general gases, water, and liquids.

The SYTF-LUGB vortex flowmeter produced by our company has remote transmission type, on-site display type, and automatic temperature and pressure compensation type. It can be widely used in chemical, petroleum, metallurgy, light industry, environmental protection, municipal, power and other sectors.

Small gas flow meters have the following characteristics:

The structure is simple and sturdy, with no moving parts, high reliability, and very reliable for long-term operation

Easy to install and maintain.

The detection sensor does not directly contact the measured medium, with stable performance and long service life.

The measured value is a pulse signal proportional to the flow rate, with no zero drift and high accuracy.

Wide range, with a range ratio of 1:10.

Low pressure loss, low operating costs, and more energy-efficient.

Using ultra-low power technology, battery powered operation can last for more than two years

Integrated design for temperature and pressure compensation, displaying flow and cumulative flow values, temperature, and pressure values without the need for sequential switching.

Structure and working principle of small gas flowmeter

When the medium flows through a triangular column at a certain velocity, an alternating vortex band called "Kamen vortex street" is generated at both ends of the body. Therefore, pressure pulsations are generated at both ends of the body, causing the test body to generate alternating stress. Under the action of alternating stress, the frequency of the alternating charge signal generated by electronic components is the same as the vortex frequency. The amplifier amplifies, filters, and shapes the charge signal into a square wave, and then sends it to the integrator for processing and display. Within a certain Reynolds number range (2X104~7x106), the relationship between the release frequency f of the vortex, the flow velocity V, and the width d of the front surface of the vortex generator can be expressed by the following formula: f=Sr.v/d, where Sr is the Strouhal number. In the straight section of the curve, Sr = 0.16， The fluid velocity can be measured by measuring the vortex frequency f. Thus achieving the purpose of measuring fluid flow rate. A clever analysis was conducted on the structure and measurement mechanism of a small gas flowmeter. Some gas meters have self-protection functions, so if the flow rate is abnormal, the gas meter will be cut off. With the arrival of summer, more and more people are starting to use appliances with relatively more gas, such as water heaters. Many people report a shortage of natural gas supply to natural gas supply companies. So how to solve it? The staff of the gas supply unit remind users that if they want to lift the over limit limit of the gas meter, they can call the customer service hotline to apply, and they will take the staff to the user's home for research.

When users approve the deletion of the content in the application form for the out of range function and provide the original and copy of the homeowner ID card, they will find technicians from the gas meter manufacturer to lift the out of range restriction. The gas meter adopts a fully cemented carbide (tungsten carbide) shielded cantilever beam structure bearing, integrating rotating bearings and pressure bearings, greatly improving the bearing life, and can work in media containing sand and a small amount of soil;

Small gas flow meters and gas meters are easy to maintain, have a self correcting structure, are lightweight, have a simple structure, can be disassembled and assembled in a short period of time, have low pressure loss, and the gas meter impeller has anti-corrosion function; Unlike smart gas meters and industrial gas meters, this gas meter has an intelligent flow indicator with non-linear accuracy compensation.

The above is a brief introduction to small gas flow meters. The two types of small gas flow meters, vortex street and MF57 series, still need to be selected according to actual situations. If you have any questions about the selection of small flow gas flow meters or small diameter gas flow meters for the project, please feel free to contact us for answers and provide related services such as quotation and installation.

The above is the complete content of the mini flowmeter product. Welcome to inquire about the selection and quotation of mini flowmeters.
