Installation of electromagnetic pipe flow meter, no longer worry about sudden changes in flow rate
View MoreReverse mounting of an orifice plate flowmeter can lead to significant changes in the measured value. After the installation is reversed, the direction of fluid flow and pressure difference measurement changes, so that the measured value may be small or negative. Therefore, the use of the orifice plate should ensure that the installation of the correct direction to avoid errors.
When the orifice flowmeter is installed upside down, the measured value will change significantly.
First of all, the working principle of the orifice flow meter is to estimate the flow rate based on the pressure difference generated when the fluid flows through the orifice plate. When the orifice plate is installed backwards, the fluid flows in the opposite direction to the original design, which causes a change in how the pressure difference is measured.
Specifically, when the orifice plate is installed backwards, the fluid flows in from the other side of the orifice plate, not the originally designed inflow side. This will cause the flow of fluid on the orifice plate to be opposite to the original design, causing the generation and magnitude of the pressure difference to change.
Due to changes in the fluid flow pattern and pressure difference on the orifice plate after the orifice plate is installed backwards, the measurement value will become inaccurate. Specifically, the measured value may be too small, because after the orifice plate is installed backwards, the resistance of the fluid on the orifice plate is reduced, resulting in a smaller pressure difference, which makes the flow value estimated by the flow meter too small.
In addition, installing the orifice plate upside down may also cause the measured value to become negative. This is because when the orifice plate is installed backwards and the fluid flows in from the other side of the orifice plate, the measured value will be very different from the actual situation, because the high and low pressure points are exactly opposite at this time, and the fluid flowing out through the throttling member If the pressure increases instead, the measured flow rate may be a negative number!
Therefore, when using an orifice plate flowmeter, you must ensure that the orifice plate is installed in the correct direction to avoid inaccuracies and errors in measurement values.
The magnetic inductive flowmeter industry, these are successful cases with comparable and reference value.
