1. Which brand of steam flowmeter is more reliable? The current mainstream reliable steam flowmeter brands are divided into two camps: domestic high cost-effectiveness and international high-end, which can be selected according to application scenarios.
1. Domestic High Cost Effective Brands 1 Weifang Aobo Instrument: a professional manufacturer with great influence in the northern region, deeply rooted in the industry for more than 20 years, mainly engaged in a full range of products such as integrated temperature and pressure compensation vortex street steam flow meters, with measurement accuracy reaching trade settlement standards, stable low-temperature operation, covering all caliber specifications, equipped with an extremely fast after-sales response system, and also providing one-stop solutions for steam energy consumption control, suitable for northern thermal power companies and industrial enterprises. Chongqing Chuanyi: an old state-owned listed instrument enterprise, participating in the formulation of multiple industry standards, its vortex street steam flow meters have good heat dissipation and high temperature resistance performance, no movable parts, long service life, complete national service network, and high recognition in heavy industries such as metallurgy and building materials Xingao Technology: A representative brand of anti vibration steam flow meters in China, equipped with dual piezoelectric differential sensing technology, which can solve the problem of vibration interference. It is optimized for low flow rate steam measurement and suitable for scenarios with large flow fluctuations. It is easy to install and debug, and is favored by small and medium-sized industrial enterprises. High and low temperature, strong pressure bearing capacity, suitable for complex industrial pipeline conditions.
II. International High end Brands 1 Emerson (USA): Its Rosemount vortex street and Micro Motion Coriolis mass flow meters have high accuracy and strong anti-interference, suitable for saturated/superheated steam, and are suitable for high-end projects. 2. Enders House (E+H, Switzerland): Promass series Coriolis and vortex street flow meters are modularized and support multi parameter measurement, with strong adaptability in food, medicine, and chemical scenarios. 3. Yokogawa Electric (Japan): DY series vortex street flow meters have excellent anti vibration performance, low flow rate stability, high market share in Asia, and are suitable for flow fluctuation working conditions.
2. Installation direction of mass flowmeter
The installation direction of mass flowmeter should ensure that the fluid direction inside its measuring tube is consistent with the flow arrow marked on the flowmeter.
. The specific points are as follows: Flow consistency: Mass flow meters usually have clear flow arrow markings, and installation must ensure that the fluid direction is consistent with this arrow. Because the sensors inside the flowmeter are designed and calibrated based on specific flow directions, flow errors can lead to measurement deviations and even damage to the flowmeter. Consider other installation factors: In addition to the flow direction, other factors should also be considered during installation, such as the length of the straight pipe section before and after the flowmeter, the support and fixing method of the pipeline, etc., which may affect the accuracy of the measurement.
