1. Piping regulations for flow meters
The piping regulations for flow meters are as follows: differential pressure flow meters: installation position: should be installed on the water distribution pipeline, and vertical installation requires special confirmation. Requirements for straight pipe section: The length of the upstream straight pipe section must comply with regulations. Pressure port orientation: Consider fluid properties to ensure no impurities enter. Positive displacement flowmeter: Installation position: horizontal installation is required for easy maintenance. Straight pipe section requirement: No straight pipe section is required. Additional equipment: A filter is required. Area flowmeter: installation pin position: vertical installation, fluid flow from bottom to top. Straight pipe section requirements: There are straight pipe section requirements. Bypass pipeline: A bypass pipeline is required. Turbine flowmeter: installation position: horizontal installation. Requirements for straight pipe sections: There are specific length requirements for straight pipe sections upstream. On site instructions: Generally, there are no on-site instructions. Vortex flowmeter: Measurement requirements: Full tube measurement is required. Installation position: Vertical installation, close to the high voltage area. Requirement for straight pipe section: Ensure that there are straight pipe sections before and after. Inner diameter of pipeline: It needs to be matched with the flow meter. Special application: Special attention should be paid to steam applications. In addition, during installation, it is necessary to consider the remote transmission and compensation methods of measurement signals, such as temperature
2. Piping Regulations for Flowmeters
Piping Regulations for Flowmeters: Flowmeters are used in petrochemical plants to measure the flow of fluid in pipelines, and their piping design must comply with the following regulations:
1. General Provisions This regulation applies to the installation design of flow meters for measuring fluid flow in pipelines in petrochemical plants.
. Including the installation design of differential pressure flow meters (orifice plate, nozzle, Venturi tube, internal orifice plate type), volumetric flow meters (elliptical gear), area flow meters (rotor flow meters), turbine flow meters (gas turbine, liquid turbine), and vortex street flow meters (compensating type, pressure type, differential pressure vortex street). In addition to complying with this regulation, the piping design of flow meters must also comply with relevant piping material grade design regulations.2. Installation position of piping for differential pressure flowmeter: Orifice plate, nozzle, Venturi tube, internal orifice plate and other throttling devices should be installed on horizontal pipelines. If vertical installation is required, it needs to be confirmed by the self-control professional.
. The length of the straight pipe section: The length of the upstream and downstream sections of the throttling device should meet the requirements of the self-control conditions. When self-control conditions are not available, piping can be carried out according to the reserved length table, and data outside parentheses should be used as much as possible to ensure zero mea
