When using a turbine flow meter, it is necessary to maintain the cleanliness of the liquid to be measured, and it must not contain impurities such as fibers and particles. When the turbine flow sensor is used at the beginning, it is necessary to fill the sensor slowly with liquid, and then open the outlet valve, and it is forbidden that the turbine flow sensor be impacted by high-speed fluid without liquid. The flow sensor maintenance period is generally half a year. During inspection and cleaning, special attention should be paid to not damaging the measurement components in the turbine flowmeter chamber, especially the impeller, and the positional relationship between the guide member and the impeller should be considered in the assembly. When the flow sensor is not in use, the internal liquid should be cleaned and protective sleeves are added at both ends of the sensor to prevent dust from entering and then stored in a dry place. When using the filter to be regularly cleaned, if it is not in use, it is necessary to clean the internal liquid, as with the sensor, with a dust jacket installed to prevent dust from entering the dry place. The turbine flowmeter sensor transmission cable can be laid overhead or buried. Before the sensor is installed, it is connected with the display instrument or the oscilloscope. After the power is turned on, the impeller can be blown or hand-pulled to make it rotate quickly and observe. There is no display when installing the sensor when there is a display.
Comparing dirty fluids or liquids that may generate gas in the turbine flowmeter measuring medium, in the case of a rather harsh working environment, will cause failure or error of the turbine flow sensor, which directly causes the flowmeter's indication error. . Errors have positive and negative values, which may be insignificant, and may completely fail. If the relationship is measured regularly, if the same differential pressure gauge indication value is found, the indicated value of the turbine flow meter will be too small, and the turbine flowmeter will be suspected of failure. When inspecting the turbine flowmeter sensor, check the sender in advance. If it is not for other reasons, the turbine flowmeter must be removed from the process line, and further careful inspection is required. According to the reason of turbine flow meter and the work experience used in the field, it is necessary to add a pair of pressure measuring ports on the pipe walls of the double pipe diameters upstream and downstream in the initial stage of flowmeter installation. When necessary, it is necessary to compare with the differential pressure gauge. The connection between the indicated value of the turbine flow meter and the differential pressure gauge was recorded under working conditions.
A gas turbine flow meter is a kind of turbine flow meter. Its working principle is to obtain the turbine rotation number through mechanical or electromagnetic induction method, so that the flow rate of the gas turbine flow meter can be obtained, and the gas guide into the turbine flow meter can be obtained. The fluid is being accelerated. The accelerated gas is applied to the blades of the turbine through the inlet passage. The momentum of the gas causes the turbine flowmeter turbine to rotate in the flow path. In a certain flow range, the rotation speed of the turbine is proportional to the volume of the flowing gas. . The choice of turbine flow meter under environmental conditions is also very important considering the surrounding environment. To provide a working environment for the turbine flow meter, there is a certain benefit to improving the stability and working life of the flow meter. If there is no indication, all parts related to the flowmeter should be checked to eliminate the malfunction. When there are impurities in the measurement fluid, a filter is added. The filter mesh is determined according to the flow of impurities.
