In the critical period of flood control, these four improvement measures of the precession vortex flowmeter can ensure the measurement

  We all know how to prevent flood and drought disasters during the critical period of flood control, and we also need to ensure the seasonal irrigation water demand of local crops. Prepare for every flood and every area drought. For the instrument person, the flow measurement of the precession vortex flowmeter will be a test. For the following four items, the editor will summarize and analyze, which can ensure the measurement of the flow.

  When the flow measuring points of the precession vortex flowmeter are the same, the error of the flowmeter in the pressure-taking hole of the meter body is smaller, and the error of the flowmeter of the pressure-checking method of the pipe pressure hole is larger; in the case of the model, use the meter body The linearity of the flowmeter is better when the flowmeter is verified by the pressure-taking method, and the linearity of the flowmeter is poor when the flowmeter is verified by the pressure-taking method of the pipeline; the error caused by the two pressure-taking methods increases with the flow rate. and gradually increased.

  During the verification process of the precession vortex flowmeter, the pressure taking method of the pipeline pressure taking hole has a great influence on the verification result of the flowmeter. The editor will introduce several improvement measures to you, so as to avoid the check of the flowmeter by taking pressure from the pressure-taking hole of the pipeline due to the blockage of the pressure-taking hole of the flowmeter body. 4 improvement measures for precession vortex flowmeter:

  (1) The user can install a filter device at the front end of the flowmeter at the site of use to filter out the sundries.

  (2) In order to prevent the flowmeter from being blocked by debris and the pressure-taking hole from rusting, it is recommended to apply lubricating oil to the external screw of the pressure-taking hole and plug the inside of the pressure-taking hole with a rubber plug when leaving the factory.

  (3) During the verification process, if the point flow changes greatly, but the flowmeter pressure does not change significantly, in order to prompt the verification personnel to take corresponding remedial measures, the verification system should set a pressure invalid alarm.

  (4) It is recommended that the flowmeter manufacturer appropriately improve the structure of the flowmeter without affecting the performance of the flowmeter, such as the position of the pressure hole to avoid it being blocked by debris.

  The above four-point summary, I don't know whether it can be a key analysis for everyone.
