1. The correct use of the Koweiler vortex flowmeter lies in installation specifications, parameter calibration, environmental adaptation, and regular maintenance. For different users, such as factory equipment maintenance personnel or novice engineers, there may be slight differences in usage points. For example, workshop operators need to pay more attention to the accuracy of daily readings, while technical supervisors need to coordinate the joint debugging of multiple devices. Here are the key usage guidelines:

1. Installation location selection: The front straight pipe section should be ≥ 15 times the pipe diameter, and the rear straight pipe section should be ≥ 5 times the pipe diameter to ensure that the fluid is fully stable - avoid strong earthquake sources (such as near pump stations) and electromagnetic interference areas (such as within 3 meters of frequency converters) - When installing vertically, it is recommended to flow from bottom to top, and when installing horizontally, it is necessary to fix it with a bracket to avoid sagging. 2 Key points for parameter calibration - Before first use, medium density compensation must be performed, and gas must be compensated for temperature/pressure. The recommended range for range calibration is between 1/3 and 2/3 of the maximum flow rate. For pulse output types, threshold filtering values (usually 0.5-1m/s) should be set to prevent false triggering Operating environment control - When the medium temperature continues to exceed 120 ℃, it is necessary to install heat dissipation fins or cooling sleeves - When measuring steam, the installation height of the condenser should be lower than that of the flow meter body - For outdoor use in winter, it is necessary

to check whether the electric tracing system starts and stops normally. For civil scenarios such as heating metering, it is recommended to wipe the sensor probe window with a soft cloth every month to prevent scale accumulation. If abnormal fluctuations in instantaneous flow are found, priority should be given to checking whether the grounding resistance is ≤ 4 Ω, and then investigating the gas content of the medium. During the selection stage, it is necessary to confirm the viscosity range of the measuring medium (usually applicable to liquids or gases with a viscosity of ≤ 10cP). For high viscosity fluids (such as heavy oil), it is recommended to use other principle instruments. Special operating conditions such as two-phase flow (gas-liquid mixture) can be improved by installing rectifiers to enhance measurement stability.

2. Kurz flowmeter parameter setting

The parameter setting of Kurz flowmeter (usually vortex type) needs to be strictly customized according to the working conditions. The manufacturer usually completes the basic calibration before leaving the factory, and users usually do not need to adjust it themselves.

2. It is recommended to set the upper limit
