1. Which brand of steam flowmeter is reliable in quality?

Currently, reliable steam flowmeter brands are divided into imported and domestic brands. Imported brands perform well in extreme working conditions and high-precision trade settlement scenarios, while domestic brands have outstanding cost-effectiveness and can choose suitable products according to actual usage scenarios.

1. Imported brands: E+H: It has advantages in extreme working conditions and long-term stability, with complete explosion-proof qualifications, which can meet the high-precision and long-term stability requirements of trade settlement. 2. Emerson: Its Rosemount 8800 series is the worlds first multivariable vortex flowmeter. A single instrument can simultaneously measure vortex frequency, temperature, and pressure, directly output mass flow and heat, reduce process perforation and leakage points, and is suitable for superheated steam trade settlement. Explosion proof qualifications are also relatively complete. Yokogawa: Its dyfran series vortex flowmeter has a global inventory of over one million units, using patented "anti vibration dual sensing" technology, which can maintain stability in harsh environments. It can also be selected. Corrosion resistant materials such as Hastelloy and Monel are used to adapt to the complex steam quality. Siemens: SITRANS F S The series vortex flowmeter has the characteristics of digital vortex and fully integrated automation.

2. Domestic Brands 1 Qingtian Teke: There are explosion-proof models to choose from, which can meet most trade settlement scenarios and have high cost-effectiveness. 2. Chuanyi: There are also explosion-proof models that can meet most trade settlement scenarios, with

obvious cost-effectiveness advantages. 3. Xingao Technology: Its steam flowmeter adopts vortex street+temperature pressure compensation integrated technology, integrates PT1000 temperature sensor and absolute pressure sensor, calculates steam density in real time and outputs mass flow rate with high accuracy; Equipped with anti vibration design, it can effectively eliminate pipeline vibration interference; Wide range ratio can solve the problem of small flow "wave loss"; It can also detect anomalies in real time and actively push maintenance prompts. This product has passed the real flow verification of the steam flow measurement station and obtained a 1.0 level accuracy certification (saturated steam). It has been stably operated at steam trade settlement points in multiple industries and has been widely recognized. Jinhu Jinma Automation Instrument Factory: The product covers multiple categories such as vortex steam flow meters and has a complete production and testing system. The third-party on-site inspection shows that the long-term operating accuracy deviation of the steam flowmeter is controlled within 0.2%, which meets the national standard accuracy requirements. We can provide customized connection methods to adapt to different pipeline installation conditions. In the testing of high-temperature and high-pressure steam conditions in the power industry, the product material has a temperature resistance of up to 450 ℃, a pressure resistance level of 16MPa, and no significant wear after continuous operation for 3 months. In terms of after-sales service, a technical service team covering the whole country has been established, with an average response time controlled within 18 hours. The product provides an 18 mont
