What is the best flow meter for measuring steam?

Project Overview

Steam flow measurement in industrial pipelines, selection is mainly through the media type, media temperature, operating pressure, flow range and other parameters to select, these instruments are widely used in a variety of industrial production process control, energy management, environmental protection, transportation, scientific research and other fields, that the measurement of steam with what flowmeter is good?

1. vortex flow meter

Principle: vortex flow meter using the Kamen vortex principle to measure the volume flow of steam. When the steam fluid on the triangular column vortex generator impact, will be alternately generated on both sides of the vortex generator regular Carmen vortex, vortex frequency and the average speed of steam there is a linear relationship between the steam flow rate can be known.

Advantages: LUB anti-vibration vortex flowmeter has a large measuring range, small pressure loss, high precision, high reliability, no moving mechanical parts, low maintenance, and long-term stability of instrument parameters.

Applicable scenarios: suitable for most steam conditions, especially when the steam pipe temperature is not greater than 300 degrees, vortex flowmeter is a cost-effective choice.

2. Differential Pressure Flowmeter

Principle: Differential pressure flowmeter is based on the Burdock equation and flow continuity equation, and determines the steam flow rate by measuring the differential pressure generated by the throttling device in the steam pipeline. Common differential pressure flowmeters are orifice plate flowmeters, nozzle flowmeters, V cone flowmeters and so on.

Advantages: Mature technology, wide range of applications, applicable to a variety of fluids and working conditions.

Applicable scenarios: for the need for high-precision measurement or more complex characteristics of the medium steam flow measurement, differential pressure flowmeter is a good choice.

3. Electromagnetic flowmeter

Principle: electromagnetic flowmeter sensor measurement principle is based on Faraday's law of electromagnetic induction, in the measurement of the pipe axis and magnetic field perpendicular to each other on the wall of the installation of a pair of detection electrodes, when the conductive liquid along the axis of the measurement of the pipe, the conductive liquid for cutting the magnetic line of motion generated by the induced potential, the induced potential by the measurement of the two electrodes on the pipe detected by the numerical value of the magnitude of the size of the: E=KBVD

Advantages: will not cause resistance or contamination of the fluid, high measurement accuracy, suitable for a variety of conductive liquid flow measurement, including acid and alkali solutions, water, sewage, etc., not subject to temperature and pressure changes, so maintenance and calibration is relatively simple.

Applicable scene: electromagnetic flowmeter has a series of excellent characteristics, can solve other flowmeter is not easy to apply the problem, such as dirty flow, corrosion flow measurement.

Vortex flowmeter is a better choice in most steam working conditions due to its cost-effective, wide measuring range, high accuracy and other advantages. However, in specific scenarios, such as high-temperature and high-pressure steam measurement or complex media characteristics, it may be necessary to consider other types of flowmeters, more flow measurement issues can be consulted Qingdao and Sheng measurement and control.
