摘要
介绍了差压式流量计分体式和一体式的优缺点和应用现状,提出将节流件、变送器及附件按标准在工艺短管上安装好并标定后一体供货,即组成一体式差压流量计,既减小了安装误差,缩短安装工时,又提高了系统准确度。详细分析了一体化差压流量计的优势、注意点及实施方案。一体化差压流量计的应用是目前趋势之一。
The advantages, disadvantages and current states of split type and integration differential pressure flowmeter are introduced. It is proposed to install throttling element, transmitter and accessories in a short process pipe segment, calibrated according standard to compose an integration differential pressure flowmeter to achieve with minimizing installation errors, reducing installation schedule and improving system accuracy. The advantages, notes and implementation plan of integration differential pressure flowmeter are discussed in detail. Application of integration differential pressure flowmeter is the trend in the future.
