Rosemount flowmeter installation will have significant effect on the measurement performance, so we need to in the previous installation problem, is very important for the following to summarizes the five big attention on the installation,
1. Check rosemount flowmeter direction:
Direction of the installation of the flowmeter will greatly affect the performance of the flow meter and the accuracy, in addition to the rotor flowmeter, most of the flow meter can be installed along any direction, and can only be installed along the vertical direction, the rotor flowmeter flow from the bottom up,
2. Ensure that measure the fluid is single-phase fluid:
Check to measure the fluid flow is single phase fluid, that is, it is a gas or liquid, if is two phase fluid, in choosing rosemount flow timing must be considered under the condition of this measure is expected,
3. The application in the field of gas/steam rosemount flowmeter installation position should be on higher position:
When the pressure and temperature conditions of the gas into a liquid, form the liquid, when this happens, any condensate will be trapped in the lower part of the pipeline, therefore, in a horizontal pipe, used for gas or steam flowmeter installation should always be placed in a higher position, in order to make the liquid from the eduction in flowmeter,
4. When installing pipeline should avoid bubbles:
Sudden pressure drop in the flow line can lead to escape of gas from the liquid solution, this is known as "cavitation", easy to items of the gasification valve and the diameter of the dramatic changes,
5. Application for gas/liquid flow meter installation must always be filled with fluid:
Of gas or liquid flow meter installed, even if there is no traffic, rosemount flowmeter also should always be placed in the position of the fluid-filled, for the second don't want to stage, should also have an escape route,
