What are the types of steam flow meters? What are the types of steam flow meters? We will provide a detailed answer. If you find it helpful, please give a thumbs up to Weidun VTON. According to the definition of imported flow meter Weidun VTON, steam flow meter refers to a flow meter that uses piezoelectric stress sensors, has high reliability, and can operate within the working temperature range of -25 ℃ to+250 ℃. There are analog standard signals and digital pulse signal outputs, which are easy to use with digital systems such as computers. It is an advanced and ideal flow meter widely used for steam and gas flow measurement The steam vortex flowmeter is a new type of flowmeter that measures fluid flow in closed pipelines based on the Karman vortex principle. Due to its excellent medium adaptability, it can directly measure the volumetric flow rate of steam, air, gas, water, and liquid without temperature and pressure compensation. Equipped with temperature and pressure sensors, it can measure the volumetric flow rate and mass flow rate under standard conditions. According to the classification of flow meters by Weidun VTON, the classification of imported steam flow meters is as follows: Types of steam flow meters

1. Differential pressure flow meters are still the most commonly used in steam flow measurement. For example, the differential pressure flow meters of the Weidun VTON brand are widely used in steam; It is based on authoritative standards and has easy to replicate test samples; Simple and sturdy structure, reliable performance, and long service life; The temperature and pressure range that can be used is wide; Low price, no need for real-time calibration and other advantages. The complete set of diff

erential pressure flowmeter instruments consists of standard throttling devices, differential pressure transmitters, and flow integrators from different manufacturers, making it flexible and convenient to use. Differential pressure flow meters are particularly suitable for measuring saturated and superheated steam at high temperatures and pressures. But there are also shortcomings, such as cumbersome installation, easy leakage, and high labor intensity for maintenance and disassembly; The range ratio is only 3:1, resulting in significant pressure loss; Due to changes in measurement conditions during use, process parameters may deviate from the design values, resulting in significant measurement errors.

2、 Vortex flowmeter has a simple structure and does not require pressure pipes; The measurement range is large, and the ratio of measurement range to sales can reach 10:1; The proportion of advantages such as low pressure loss in saturated steam flow measurement is increasing. Its installation difficulty is similar to that of orifice plates, with certain requirements for straight pipe sections. For example, the imported vortex flowmeter of Weidun VTON is often designated as a steam flowmeter. But there are also shortcomings, such as: regular calibration cannot be done by ordinary users and needs to be disassembled for inspection; Its stability is affected by the flow velocity, and the stress type vortex flowmeter is sensitive to vibration and easily affected by pipeline or equipment vibration, resulting in measurement errors. It is also limited by temperature and usually cannot exceed 300 ℃ (vortex flowmeters are suitable for measuring saturated steam flow and cannot be used for measuring superheated steam flow). It
