What is the difference between high-temperature and low-temperature vortex flowmeters? The long-term reliability of the vortex flowmeter can be extended to two types: high-temperature and low-temperature. The high-temperature vortex slag disturbance leakage flow meter can achieve accurate measurement up to 350 ℃, and can be applied to the measurement of high-temperature overheating and saturated water vapor. The low-temperature vortex flowmeter can achieve measurements as low as -196 ℃, suitable for applications with low temperatures such as liquid oxygen. 1. High temperature type can reach up to 450 ℃/low temperature type can reach as low as -196 ℃ and parameter settings are simple. 2. Low temperature type can synchronously display instantaneous flow rate and cumulative flow rate during process diagnosis, as well as analog/pulse dual output.

2. Which brand of steam flowmeter is more reliable?

Currently, mainstream and reliable steam flowmeter brands are divided into two camps: domestic high cost performance 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 north

ern 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. Structure, high and low temperature resistance, strong pressure bearing capacity, suitable for complex industrial pipeline working 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 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.
