Which flow meter is suitable for hot water boiler water supply flow measurement

Project Overview

Due to process specificity, vacuum hot water boiler water supply flow measurement needs flowmeter, as the control of the key detection equipment, requires high reliability; due to high demand, requires lower cost; in addition, due to the installation of the equipment, the need for smaller installation space; also requires good anti-interference. In the face of a variety of flowmeter options, what kind of flowmeter is more suitable for hot water boiler water supply flow measurement, this article for the field of several commonly used flowmeter, do a brief analysis:

• 一、Mechanical water meter: Advantages Installation of straight pipe section requirements are low, inexpensive, not subject to electrical interference Disadvantages Low precision, after a period of time, mechanical wear and tear, flow error is large, can not interlock control.
• 二、Orifice plate flowmeter advantages of higher measurement accuracy, can also output interlocking control signals disadvantages of the installation of the required straight pipe section is longer, the installation of the flowmeter requires a larger space, range ratio is low, the pressure loss is greater.
• 三、Ultrasonic flowmeter advantages range ratio is wide, can meet the control needs disadvantages straight pipe section requirements, long-term operation of the sensor is easy to aging and thus reduce the accuracy, can not meet the matching requirements of these commonly used flowmeter has its own advantages, but in the field of hot water boiler water supply flow measurement have defects, is not suitable for large-scale applications, and the Qingtian instrumentation electromagnetic flowmeter, a very good solution to this problem. Stable and reliable operation saves space and reduces the cost of enterprise anti-interference measurement range of wide speed and low power consumption.
