According to the properties of the medium, vortex flowmeters can be used to measure steam, and differential pressure flowmeters can also be used: such as orifice flowmeters, cone flowmeters, etc. However, the medium steam is generally superheated steam, and the temperature is relatively high. The maximum measurement temperature of the vortex flowmeter does not exceed 350 °C, but the differential pressure flowmeter has a higher temperature resistance than the vortex flowmeter because the sensors are purely mechanical mechanisms. , which is the advantage of differential pressure flow meters. However, when the differential pressure flowmeter is installed, because there are many accessories such as pressure guiding pipes, condensers, and three-valve groups, it must be regularly maintained during use to check whether there are leakage points, and antifreeze measures must be taken in winter. Therefore, the differential pressure type flowmeter should be maintained regularly, and there are more vortex flowmeters, but after the vortex flowmeter is installed, if there is no special reason, maintenance is not required.
The vortex flowmeter has a wide range of applications and can measure the mass flow and volume flow of superheated steam, saturated steam, compressed air and general gases, water and non-corrosive liquids.
If it is to measure steam media such as superheated steam and saturated steam, because the density of the medium changes with the change of temperature, a vortex flowmeter with temperature and pressure can be selected, so that flow, temperature and pressure can be displayed at the same time. The display unit can also be a mass unit, such as: KG/H, etc.
If the steam temperature exceeds 250℃, you need to choose a split vortex flowmeter. The split vortex flowmeter includes: 1. Vortex pulse vortex flowmeter, 2. Flow totalizer, 3.. Pressure transmitter, 4 .. temperature sensor PT100,
