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. St
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 modular designed to support multi parameter measurement, and have strong compatibility in food, pharmaceutical, and chemical scenarios. 3. Yokogawa Electric (Japan): DY series vortex street flow meters have excellent anti vibration performance, stable low flow rate, high market share in Asia, and are suitable for flow fluctuation conditions.
2. Is there any difference in the effectiveness of using a steam flowmeter in a straight or inverted position?
There is a significant difference in the effectiveness of using steam flow meters in a simulated open and inverted manner, which directly affects measurement accuracy, equipment service life, and operational safety Measurement accuracy difference: The vast majority of mainstream steam flow meters (such as orifice plates, vortex streets, and turbine types) have clear fluid flow design requirements. When installed, the fluid passes through the sensor along the calibrated flow direction, and the measurement error conforms to the factory calibration range. Inverted flow will disrupt the physical mechanism of flow detection: the pressure difference signal of the orifice flowmeter will reverse, the calculation logic of the vortex shedding frequency of the vortex flowmeter will fa
