1. What is an integrated vortex flowmeter?
The integrated vortex flowmeter is a very accurate instrument for measuring flow rate, which can be used together with the flow integrator to measure liquid flow rate and total amount.. And it can also be used in many other industries, bringing certain benefits to other fields as well. Integrated vortex flowmeter is mainly used for flow measurement of industrial pipeline media such as gas, liquid, vapor and other media. The characteristics of integrated vortex flowmeter are small pressure loss, large range, high accuracy, and almost no influence of fluid density, pressure, temperature, viscosity and other parameters when measuring volumetric flow rate under working conditions. The temperature and pressure compensation integrated type is equipped with temperature and pressure sensors, which can directly measure the temperature and pressure of the gas medium for gas flow measurement, thereby displaying the standard residual condition and volume flow rate of the gas.
2. Verification Regulations for Gas Differential Pressure Flowmeters
The verification of gas differential pressure flow meters must strictly follow the JJG 640-2016 regulations, and the core process includes equipment configuration, flow point selection, and fluid pretreatment.
. 1. Scope of application for verification: This applies to integrated or split type Shenmufan differential pressure flow meters, including initial verification, subsequent verification, and inspection during use, including standard throttling components and differential pressure devices. two Equipment and configuration requirements: Differential pressure transmitter: At least 2 devices with different ranges sh
(1) After the equipment is installed for durability, perform initial state inspection and calibration;
(2) Adjust the flow rate gradually according to the preset flow point, record the differential pressure value and instantaneous flow rate; (3) Repeat the detection until it meets the convergence criteria for single point data. seven The data recording and judgment ultimately require calculating the indication error and repeatability index of the flowmeter to determine whether it meets the threshold range allowed by the regulations.
3. What are the precautions for using an integrated balance orifice flowmeter?
The integrated balance orifice flowmeter works based on the principle of differential pressure. When using it, the following precautions should be taken: the principle of shortest distance for laying the differential pressure signal pressure pipe: the pressure pipe should be laid at the shortest distance to reduce interference and attenuation during signal transmission and ensure the accuracy of the differential pressure signal.. The relationship between pipe diameter and length
