1. What are the commonly used steam flow meters?
There are mainly two types of steam flow meters: differential pressure flow meters and vortex flow meters.. Differential pressure flowmeter: Overview: Differential pressure flowmeter is the most widely used type in steam flow measurement. It calculates the flow rate by measuring the differential pressure generated when the fluid flows through the throttling device. Classification: According to the different throttling devices, differential pressure flow meters can be divided into various types, such as orifice flow meters, nozzle flow meters, indicator Venturi flow meters, and averaging tube flow meters (including Annubar, Velbar, Probar, etc.). In addition, there is a special type of differential pressure flowmeter - balance flowmeter, which has unique advantages in certain specific situations. Characteristics: Differential pressure flow meters usually require temperature and pressure compensation when measuring steam flow to ensure the accuracy of the measurement results. In recent years, some advanced differential pressure flow meters, such as Frosts MVX100 multivariable integrated differential pressure flow meter, have achieved built-in temperature and pressure sensors, which can directly output mass flow without external compensation devices, greatly improving the convenience and accuracy of measurement. Vortex flowmeter: Overview: Vortex flowmeter is another commonly used steam flowmeter. It measures the flow rate by utilizing the proportional relationship between the vortex frequency generated by the fluid flowing through the vortex generator and the flow velocity. Features: Vortex flowmeter has the advantages of simple structure, wide measurement ra
2. What are the types of steam vortex flowmeters?
There are various types of steam vortex flowmeters according to different classification standards. Taking the LUB series vortex flowmeter as an example, there are mainly the following types: local display type. Characteristics: Flow data can be directly displayed on site without the need for additional display devices or cumbersome transmission systems. Operators can obtain flow information in real time at the flowmeter installation site.. Applicable scenarios: Suitable for situations where real-time flow data needs to be viewed on-site and there is no need to transmit the data remotely to the control room, such as some small steam usage workshops or equipment. Characteristics of flange mounting type: The flowmeter body does not have a flange, while there is a flange on the pipeline. During installation, tighten the pipeline with bolts to clamp the flowmeter in the middle of the pipeline. This connection method is relatively easy to install and disassemble, without the need for tedious flange docking op
