Treatment Measures |
| Float flowmeter pointer jitter | 1. Medium pulsation. | 1. Increase the damping. |
| 2. Unstable air pressure. | 2. Using voltage or current stabilization device. | |
| The pointer stops at a certain position and does not move | 1. Open the valve too fast and the float is stuck. | 1. Slow down the opening speed of the valve. |
| 2. The float guide rod is not centered with the stop ring. | 2. Remove the meter and adjust it. | |
| Large measurement error | 1. The installation does not meet the requirements. |
1. Vertical or horizontal installation inclination is not more than 20 degrees. |
| 2. The density of the liquid medium varies widely. |
2. Calculate the error correction factor and multiply the reading to convert it to the true flow rate. |
|
| 3. Temperature pressure has a large impact. |
3. Adopt temperature and pressure compensation. |
|
| 4. Pipeline vibration. | 4. Find a professional to adjust the position of the components. |
