2. What flow meters are commonly used on steam pipelines?

The commonly used flow meters on steam pipelines mainly include the following types, which need to be selected based on actual working conditions, measurement accuracy, range, pressure loss, and installation and maintenance costs.

1. Working principle of vortex flowmeter: Based on the Karman vortex street principle, the steam flow rate is calculated by measuring the alternating vortex frequency generated by the impact of steam fluid on the triangular cylinder vortex generator.

. The vortex frequency is directly proportional to the average flow velocity of the fluid, and the volumetric flow rate can be calculated by combining the cross-sectional area of the pipeline. Applicable conditions: Preferred for steam pipeline temperature ≤ 300 ℃, with low cost a Yantai steam flowmeter

nd wide applicability. Large measurement range, low pressure loss, high accuracy (usually ± 1%~± 2%), and high reliability. No movable mechanical parts, low maintenance, and long-term stable instrument parameters. Structural composition: sensors, converters, display instruments. Sensors (such as piezoelectric stress sensors) convert vortex mechanical effects into electrical signals and output flow values after processing. Signal output: Supports analog signals (4-20mA) or digital signals (pulse signals) for easy data transmission and reading. Image: The vortex flowmeter is disassembled to measure the vortex frequency and calculate the flow rate Working principle of differential pressure flowmeter: Based on Bernoulli equation and flow continuity equation, the flow rate is determined by measuring the differential pressure generated by throttling devices (such as orifice plate, nozzle, V-cone). Common type: Orifice flowmeter: simple structure, but significant pressure loss. V-cone flowmeter: utilizing the V-cone throttling effect, with low pressure loss and high measurement accuracy, suitable for high viscosity or dirty media. Features: Suitable for high-temperature and high-pressure steam pipelines, but requires regular maintenance of throttling devices. The measurement accuracy is affected by fluid density and temperature, and needs to be combined with temperature and pressure compensation. Figure: Differential pressure flowmeter generates differential pressure measurement flow rate through throttling device Working principle of splitter rotor steam flowmeter: After entering the throttle body, the steam is divided into two paths: one part passes through the main pipe throttle hole like a plate; The other part impacts the
