Flowmeter challenges
Traditional mechanical flowmeters, such as differential pressure flowmeters, positive displacement flowmeters, and variable area flowmeters, are already in the stage of popularization, with fierce price competition, decreasing profit margins, less technological innovation, and relatively mature markets. . Frost & Sullivan believes that achieving product differentiation and customized production is an important breakthrough for manufacturers in the fierce competition in mature markets. Based on Frost & Sullivan's analysis of the needs of industry users, the user community expects manufacturers to provide automated equipment that will bring tangible benefits to the production process. Users will have specific requirements in the application process, such as: application in the special environment of the petrochemical industry, the need for rugged design and explosion-proof certification; user demand for Coriolis flowmeter designed for straight pipe. How to effectively obtain the actual needs of users and improve the traditional products is a challenge to the manufacturer's differentiated and customized production process.
Guiding users to accept and use new technology flow meters, such as ultrasonic flow meters, electromagnetic flow meters, and thermal mass flow meters, is another challenge for manufacturers to make the market bigger and stronger. In fact, the new technology flowmeter mentioned above has been developed and applied more than ten years ago. How to make customers realize that using the new technology flowmeter can effectively improve the production efficiency is an important issue for manufacturers.
In addition, new technology flowmeters are constantly being introduced into various industries, and fast and efficient after-sales service is also crucial for manufacturers. In particular, the use of Flowfield based on Foundation Fieldbus and Profibus PA bus has certain requirements for software technology. Effective services can provide users with more suitable solutions and close to users.

Product advantage and preservation
The vortex flowmeter adopts micro-power high-tech, and can be operated continuously by lithium battery for more than one year, which saves the purchase and installation cost of cables and display instruments, and can display instantaneous flow and accumulated flow on the spot. The temperature-compensated integrated vortex flowmeter also has a temperature sensor that directly measures the temperature of the saturated steam and calculates the pressure to show the mass flow of the saturated steam. The temperature and pressure compensation integrated type has a temperature and pressure sensor. The gas flow measurement can directly measure the temperature and pressure of the gas medium, thereby indicating the volumetric volume flow of the gas.
In order to prevent accidental damage to the instrument, please keep the packaging status of our company when it is shipped to the user.
After the instrument arrives, it should be installed in time to avoid the insulation performance of the flow converter being reduced due to unexpected factors, and the metal parts are corroded. If you need to store for a long time, please observe the following:
1. When storing, try not to unpack.
2. The storage location should have the following conditions:
3. With rainproof and waterproof facilities
4. Not susceptible to mechanical vibration or shock
5. The instrument should be stored in the temperature and humidity ranges listed in the table below. The ideal temperature and humidity is 25 ° C, 65%
6. Ambient temperature -20 ° C ~ +60 ° C
7. Relative humidity 5% to 90%

Several problems of steam metering and their solutions
Steam is one of the important energy sources for enterprise production. It is the main heat energy for urban central heating and an important indicator for economic accounting. Therefore, the accuracy of steam metering is particularly important.
In order to solve the problem of heating for employees, the company has updated the original boiler equipment, adding 4 new boilers (2 sets of 25t/h, and another 2 sets of 35t/h). The DCS realizes the automatic control of the boiler system, and the product is saturated steam.
Analysis of problems and influencing factors
Starting from the boiler ignition operation in November 2010, the steam flow often shows the maximum value, and the differential pressure signal measured by the differential pressure transmitter exceeds 20 mA. The same is true when the load is low and the actual flow is small. In this case, steam flow measurement does not provide a safety reference for boiler operation, and it cannot be used for cost accounting.
In response to this phenomenon, the design of the project uses a V-cone flowmeter, equipped with an intelligent differential pressure transmitter, and the measurement signal is sent to the DCS for calculation and display.
