到底如何了解其优势和特点：威力巴流量计的安装到底如何进行安装来满足，怎样才能威力巴流量计进行正确的安装和布置，我给大家讲讲关于一些威力巴流量计的方法： 第一：可以测量气体、液体和蒸气等各种介质，应用范围广泛，且测量信号稳定、波动小。 How to understand the advantages and characteristics of Verabar flowmeters: How to install Verabar flowmeters to meet the requirements, how to properly install and arrange Verabar flowmeters, I will tell you about some Verabar flowmeters. Method: First: It can measure various media such as gas, liquid and vapor, it has a wide range of applications, and the measurement signal is stable and the fluctuation is small. Verabar's pressure loss is only about 1.6% of the orifice pressure loss. Within a certain temperature and pressure range, the density change is greater than the measurement accuracy requirement. Second: Verabar flowmeter installation is divided into on-line type and universal type, especially on-line type can be installed without stopping production. It overcomes the characteristics of traditional detection component installation, cleaning must be stopped, and inconvenient loading and unloading. The pressure-sensing pipe and valve are directly connected to the transmitter, which reduces the intermediate links such as the pressure-taking pipeline, reduces the cost, and reduces the failure point. Third: simple installation, only need to open a small hole in the pipe and weld a base, without cutting the pipe, some media can be installed online, and the probe can be taken out for inspection at any time, the installation cost is low, and the maintenance is basically free; Non-restrictive throttle design, at least 95% lower than the permanent pressure loss of the orifice plate; As the Verabar connector can be directly connected to the transmitter, three sets of valves and impulse pipes are not needed, which prevents leakage and blockage of the impulse pipes Measurement errors caused by
在现代社会的工业生产过程的检测和控制中，“流量”是一个十分重要的参数。 Verabar flowmeter is a very important parameter in the detection and control of industrial production process in modern society. So there are many invented methods of flow measurement. The main popular ones are: speed type flow measurement, differential pressure type flow measurement, volumetric type, and mass type. Among them, using the differential pressure principle to measure fluid flow is the most widely used method. Traditional orifice plates, nozzles, and venturi tubes are common differential pressure generating devices. However, due to their serious throttling loss problems, large workloads in installation and maintenance, and measurement accuracy are not very high, they are gradually being removed. Replaced by a differential pressure device. This paper introduces a new type of differential pressure flow probe, which is equipped with a high-performance transmitter and a flow totalizer to form a flow measurement system. The operation test has been performed and has achieved good results. The design principle of the differential pressure flow measurement system is composed of Verabar flow probe, differential pressure transmitter, pressure transmitter, temperature element and intelligent flow totalizer.
计探头检测出管道内蒸汽流量的差压信号，经差压变送器转换为4-20mA电流信号，输入智能流量积算仪进行蒸汽流量计算、显示和累计，压力变送器把管道内蒸汽的压力也转换为4-20mA电流信号，和温度元件测得的蒸汽温度信号一起输入流量积算仪进行蒸汽的温压补偿，使流量测量更加精确。 The differential pressure signal of the steam flow in the pipeline is detected by the Verabar flowmeter probe, converted into a 4-20mA current signal by the differential pressure transmitter, and input to the intelligent flow totalizer for steam flow calculation, display and accumulation. Pressure transmitter The steam pressure in the pipeline is also converted into a 4-20mA current signal, and the steam temperature signal measured by the temperature element is input to a flow totalizer to compensate the steam temperature and pressure, which makes the flow measurement more accurate. Among them, the Verabar flow probe is the core part of the measurement system, and its performance index is directly related to the accuracy of the steam flow measurement. It is the key to the entire flow system experiment. The performance of the transmitter and totalizer also affects the flow. Measurement.
