Coriolis flow meters supplier by bjssae.com: When to use a volumetric flow meter or a mass flow meter? A volumetric flow meter is recommended when high accuracy is not required when measuring gas volumetric flow. However, when comparing results, a volume flow meter requires additional temperature and pressure compensation. Mass flow meters, on the other hand, measure flow rate independent of gas pressure and temperature. As a result, mass flow measurements are more reliable, accurate, and repeatable.

It is the existence of domestic brands that has forced the prices of foreign brands to drop by 1/2-2/3 in recent years. The production and R&D investment of natural gas turbine meter is relatively large, and the prices of enterprises with certain strength will also be higher in domestic brands. But even then, they are only about half the price of high-end international brands. Therefore, it is recommended that users choose carefully on the basis of comprehensive consideration of their respective use requirements and procurement costs. Don’t pursue low prices too much, nor do you need to pursue imported brands inappropriately.
To calculate the steam mass flow from the frequency signal output by the frequency output vortex flowmeter, you only need to know the current working condition of the fluid, while the temperature and pressure compensation of the analog output vortex flowmeter is only the error caused by the deviation of the current working condition from the design working condition. Compensation, therefore, not only need to know the current conditions, but also need to know the design conditions. The data of the latter working condition often causes errors due to the loss of data due to the passage of time or personnel changes. In contrast, the frequency output vortex flowmeter does not have this problem.
American first unit of coriolis mass flow meter entered China SINCE 1987. Beijing Sincerity belongs to the state owned enterprise, which is Beijing institute of chemical industry, SINOPEC automation instrument department. SINOPEC has invested large amount of money to ask Beijing Sincerity to develop the VERY FIRST Chinese domestic coriolis mass flow meter since 1987. Chinese very first unit of U shape coriolis mass flow meter was successfully developed by Beijing Sincerity Group. Beijing Sincerity won the National Science and Technology progress awards. – SINCER 1989.
Ultrasonic flow meters enable users to perform flow measurement inspections at many points in the flow process without the need for permanent installation. This universal driving time timer has a dual-function button interface, an ergonomic handheld design, and a beautiful backlit color digital display that greatly simplifies setup and data collection. Compared with other traditional flowmeters or high temperature ultrasonic flow meter, it has the characteristics of high accuracy, high reliability, high performance, and low cost. The flowmeter also has other advantages: TVT technology design. Fewer hardware components, low-voltage broadband pulse transmission, and low power consumption. Clear, user-friendly menu selections make the flowmeter easy to use. Daily, monthly and yearly total traffic. The parallel operation of positive, negative, and net flow is displayed cumulatively by a scale factor (span) and a 7-digit number. Discover additional details on https://www.bjssae.com/.

It has been considered in the design that the steam becomes superheated, or it is difficult to determine which state it is in, or sometimes it is superheated and sometimes saturated, so the temperature and pressure compensation is adopted, and the above phase change has no effect on the measurement results. Considering saturated steam in the design, and adopting pressure compensation, the above-mentioned phase change will bring about a small error, that is, the compensation error caused by the density difference corresponding to the difference between the superheated steam temperature and the saturated steam temperature. The design is based on saturated steam, but temperature compensation is used, that is, the temperature of superheated steam is used as the saturation temperature to check the density table, which will generally cause large errors.
