The use of the orifice meter scale and installation

Abstract: the use of orifice meter scale and installation information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. In view of the orifice flowmeter is now, every large and small coal mines will not lack of a device, for this product and you know it is how to use and install? Below is provided by the huaian ruentex group instrument co. , LTD. The use of information and installation information. The orifice plate. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the use of orifice meter scale and install the article details. In view of the orifice flowmeter is now, every large and small coal mines will not lack of a device, for this product and you know it is how to use and install? The following information is provided by the huaian ruentex group instrument use and installation information. The use of orifice meter: orifice meter for the determination of gas flow in gas drainage pipeline. When gas concession road through the orifice plate, the velocity increases, the pressure difference on both sides of the orifice plate, and the flow rate and pressure difference exists between a constant relationship, through the pipe pressure difference can be calculated in the flow of gas. The installation of the orifice meter: 1. Orifice meter consists of the orifice plate, mouth and take pressure steel pipe, the installation process, attention should be paid to the installation direction of orifice plate, concrete as shown. 2. Orifice plate installation requirements ( 1) Orifice upstream side of the measuring tube length for 10 d, the length of the downstream side of 4 d. （ 2) The measuring tube must be meet the surface clean, no sag and sediment, the relative roughness K/D should be less than or equal to zero. 001. （ 3) Orifice required for upstream and downstream straight pipe length should not be less than the following requirements: ( 4) Sounding pipe length of straight pipe inner surface roughness of the K/D less than or equal to 0. 001. （ 5) When installed in the measuring tube orifice, open around limited to measure the tube axis coaxial, orifice upstream side face perpendicular to the pipe axis, vertical degree is less than & plusmn; 1%. These are for the use of the orifice flowmeter and installation materials, every friend you understand? If you don't understand can directly to me. According to the current coal mine accidents, huaian ruentex group specializing in the production of the instrument without power, without artificial high technology products. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
