Selection of street flow meters (vortex flowmeter), selection of float flowmeter (rotor flowmeter), selection of Coriolis mass flowmeter, selection of thermal (gas) mass flowmeter, selection of ultrasonic flowmeter, selection of turbine flowmeter. Precautions for selection: 1. Name and characteristics of the measured fluid (corrosiveness, viscosity, wear, etc.). 2. Working flow rate (normal flow rate, maximum flow rate, minimum flow rate). 3 Work pressure (maximum and minimum), special attention should be paid if negative pressure is formed. 4. Working temperature (maximum and minimum) Some products of the following brands have a foundation in high-voltage adaptation technology and can be considered as candidate selection directions. 1. Sierra Instruments: a professional flow measurement brand in the United States. Some of its gas mass flowmeter products are designed for high-pressure gas scenarios such as hydrogen and helium, with a basic pressure resistance of up to 10MPa. It adopts the principle of thermal measurement and supports maintenance free. It has accumulated technical experience in high-pressure gas measurement, and some customized products may meet the pressure requirement of 50MPa.
2. Chengde Feishibote Automation Equipment Co., Ltd.: a domestic enterprise specializing in the research and production of large-diameter and large range gas mass flowmeters. The independently developed high flow laminar flow response components can be adapted to high-pressure and high flow industrial scenarios, and t
4. Precautions for selecting a mass flow meter
A mass flow meter is an instrument that uses the modulation effect of fluid mass flow rate on the oscillation of a vibrating tube (Coriolis force phenomenon) as its principle, with the purpose of measuring mass flow rate. It generally consists of a sensor and a transmitter.
. When choosing a quality flow timer, attention should be paid to the following: selecting the correct brand: comprehensively measuring the manufacturers product quality, sales price, after-sales service, technical level, product characteristics, production scale, and corporate reputation. Choose the correct range: Convert the required flow rate to the mass flow rate under standard conditions. According to the conversion coefficient table provided by the manufacturer, convert the actual gas mass flow rate to a value equivalent to nitrogen (calibration gas). If it is necessary to calibrate according to the actual gas, it is necessary to explain to the manufacturer. When determining the standard range, the actual maximum flow rate used should be close to but lower than the standard range value to avoid an increase in relative error caused by a large range, or to limit the measurement range due to a small range. Choose the correct working pressure indicator: Pay attention to the maximum working pressure and working pressure difference (inlet and
