For orifice flowmeter, it is now an indispensable equipment for every large and small coal mine. Do you know how to use and install this product? The following is provided by Huaian Runtai Instrument Co., Ltd. Usage information and installation information. orifice plate. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following are the details of the use and installation of orifice flowmeters. For orifice flowmeter, it is now an indispensable equipment for every large and small coal mine. Do you know how to use and install this product? The following is the use information provided by Huaian Runtai Instrument and installation information. Use of orifice flowmeter: The orifice flowmeter is used to measure the gas flow in the gas drainage pipeline. When the gas passes through the orifice plate through the pipeline, the flow rate will increase, and a pressure difference will be generated on both sides of the orifice plate, and there is a constant relationship between the flow rate and the pressure difference. The flow rate of the gas in the pipeline can be calculated through the pressure difference. Installation of the orifice flowmeter: 1. The orifice flowmeter is composed of an orifice plate, a pressure nozzle and a steel pipe. During the installation process, attention should be paid to the installation direction of the orifice plate, as shown in the figure. 2. Requirements for orifice plate installation (1) The length of the measuring tube on the upstream side of the orifice plate is 10D, and the length on the downstream side is 4D. (2) The surface of the measuring tube must be clean, free of dents and deposits, and the relative roughness K/D should be less than or equal to 0.001. (3) The length of the straight pipe required for the upstream and downstream of the orifice plate shall not be less than the following requirements: (4) The roughness K/D of the inner surface of the straight pipe section beyond the length of the measuring pipe is less than or equal to 0.001. (5) When installing the orifice plate in the measuring tube, the circumference of the opening is limited to the axis of the measuring tube being coaxial, and the upstream end face of the orifice plate is perpendicular to the axis of the pipeline, and the verticality is less than±1%. These are the information for the use and installation of the orifice flowmeter. Do you understand, my friends? If you don't understand, you can contact me directly. According to the current occurrence of coal mine accidents, Huaian Runtai Instrument specializes in the production of this high-tech product without power supply and without labor. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'Use and Installation of Orifice Flow Meter'
