Insertion vortex flowmeter correct installation conditions and installation steps

Project Overview

The correct installation of an insertion vortex flowmeter is critical to ensuring its measurement accuracy and stability. The following are the conditions and steps for its correct installation:

1. Correct installation conditions

(1) Pipe conditions:

1. The pipe should be in a horizontal state, for installation directly above the pipe.

2. The inner wall of the pipe should be smooth and free of burrs, welding slag and other impurities that may affect fluid flow.

3. The diameter of the pipe should match the specifications of the flow meter to ensure measurement accuracy.

(2) Fluid conditions:

1. The fluid should be a single-phase fluid to avoid multi-phase fluids (such as gas-liquid mixtures) from affecting the measurement.

2. The flow state of the fluid should be stable to avoid unstable flow phenomena such as eddy currents and pulsations.

3. The temperature, pressure and other parameters of the fluid should be within the measurement range of the flow meter.

(3) Environmental conditions:

1. The installation environment should be free of interference sources such as strong magnetic fields and strong electric fields, so as not to affect the measurement accuracy of the flow meter.

2. The ambient temperature, humidity, etc. should meet the usage requirements of the flow meter.

2. Installation steps

(1) Preparation work:

1. Prepare the corresponding installation tools and materials according to the pipe diameter and flow meter specifications, such as Gas welding equipment, flanges, gaskets, ball valves, etc.

2. Check whether the flow meter and its accessories are intact and make sure they are not damaged or missing.

(2) Hole opening and welding:

1. On the horizontal pipe directly above the pipe where the insertion vortex flowmeter needs to be installed, use gas welding to open a hole slightly smaller than φ100mm. Round hole (the specific size is determined according to the flowmeter specifications).

2. Remove burrs and welding slag around the round hole to ensure that the edge of the round hole is smooth and free of damage.

3. Place the short pipe with flange provided by the manufacturer above the round hole, keep the short pipe vertical to the pipe, and weld it firmly.

(3) Install the flow meter:

1. Place a gasket at the round hole to prevent fluid leakage.

2. Insert the flow meter into the short pipe and ensure that the flow meter and flange are tightly connected.

3. If a ball valve is used, the ball valve should be installed on the short pipe and connected, and then the ball valve should be opened to check the fluid flow.

(4) Adjustment and calibration:

1. Adjust the insertion depth of the flow meter to ensure that the central axis of the probe coincides with the central axis of the pipe.

2. Check whether the fluid flow direction is consistent with the flow direction indicator arrow on the flow meter. It is strictly forbidden to pull the flow direction indicator rod.

3. Calibrate as needed to ensure the measurement accuracy of the flow meter.

(5) Inspection and testing:

1. Check whether each connection part is tight and reliable and there is no leakage.

2. Slowly open the valve to observe the operation of the flow meter and check whether there are any abnormalities.born.

3. If leakage or other problems are found, they should be dealt with promptly and reinstalled and tested.

(6) Recording and identification:

1. Record the installation location, model, specification, measurement range and other information of the flow meter.

2. Attach identification plates or labels to the flow meter and its accessories for future maintenance and management.

By following the above steps and conditions, the correct installation and stable operation of the insertion vortex flowmeter can be ensured. At the same time, you should also pay attention to regular maintenance and inspection during use to ensure that it maintains high accuracy and stability for a long time.
