How to install a gas turbine flowmeter?

1. Transportation and turnover management before installation According to JJG1037-2008 "Turbine Flow Meter Calibration Regulations", online flow meters must be calibrated and qualified by the metrological calibration department before use. Qualified flow meters should have the inlet and outlet of the gas turbine flow meter plugged (or sealed), and then opened before installation to prevent dust particles and foreign objects from entering the meter and affecting its operation and accuracy. At the same time, during transportation turnover, it is not allowed to pull or impact the head of the flowmeter, as well as the transmission lines of the flow sensor, temperature sensor, and pressure sensor, to prevent signal transmission problems.

Secondly, the installation position of the flange connection sealing gasket should be correct. Due to the limitations of the flowmeter installation conditions, some construction units use the method of making sealing gaskets on site with rubber sheets.

. In the production process, there have been incidents of non-standard and small inner holes, especially during the flange fastening process. The sealing gasket is not placed correctly, and the center of the inner hole deviates greatly from the axis of the pipeline flowmeter, causing the inner hole wall of the sealing gasket to block the ventilation pipe section of the pipeline flowmeter, resulting in changes in the direction of the flowmeter airflow, uneven force on the impeller, which can easily shorten the service life and reduce flow accuracy.

III. The normal installation position for the relative distance between the gas filter and the flow meter is to directly in

stall and connect the gas filter, valve, and flow meter in order.

. In actual construction, it is often seen that construction units install filters and flow meters with large intervals for convenience, resulting in connecting pipelines between the filters and flow meters. Due to the perennial corrosion of the inner wall of the pipeline, coupled with the fast gas flow rate, corrosive substances (iron oxides) can easily enter the flowmeter directly, affecting its normal use, clogging the rotor bearings, and affecting measurement accuracy.

4. Selection of Gas Filters There are two commonly used structures for gas filters: one is the Y-shaped structure; Another type is the T-shaped structure. The Y-shaped structure is compact, with a small filtering area and a low price; The T-shaped structure has a large volume, large filtration area, high price, long maintenance cycle, and the T-shaped structure filter has an impurity discharge valve. So it is recommended to use a T-shaped structure filter to improve the stability of the flowmeter and extend the maintenance cycle. In addition, if the gas quality measured by the gas turbine flowmeter is poor (such as coke oven gas, etc.), it is best to choose a filter with a differential pressure gauge and an impurity discharge valve, which is more beneficial for the maintenance and management of the filter and flowmeter.

Fifth, problems that are prone to occur when installing new flow meters. Newly installed gas turbine flow meters often require various on-site processing, welding, oil coating and anti-corrosion work on the pipeline, which inevitably produces particles, debris, paint and other substances. Improper management can easily enter the inner wall of the pipeline
