Please help with the normal installation method of installing pressure gauges and temperature gauges on pipelines.

Sofa~~~ The pressure is in the front and the temperature is in the back. If the thermometer is in front of the pressure gauge, it will affect the measurement accuracy of the pressure gauge.

If the installation location is high and the lighting conditions are poor,； You can choose 150mm or 200-250mm. The pressure gauge should be calibrated before installation, and it can be installed and used only after it is qualified. During installation, the pressure gauge should be fixed on a specially processed joint and a gasket should be added. ； Do not wrap hemp wire or apply it directly to the valve. The pressure gauge should be installed in a location convenient for operation and maintenance. To ensure accurate measurement, the pressure points must be representative. For example, you should choose a straight pipe section with a stable flow rate, not a bend or dead corner of the pipe. ； Pressure pipes are generally not allowed to extend into equipment and pipelines. There are also certain requirements for the installation location of the pressure point. Take horizontal or inclined pipelines as an example.: 1. When the medium is gas. in the upper part of the pipe. 2. When the medium is steam, the angle between the upper half of the pipe and the horizontal centerline is within the range of 0-45 degrees, preferably on the horizontal centerline of the pipe. 3. When the medium is liquid, the angle between the lower half of the pipe and the horizontal centerline is within the range of 0-45 degrees. If conditions are limited, a more reasonable location can be selected based on the actual situation. Install a pressure gauge on-site with water vapor or medium temperature exceeding 80 degrees. In order to prevent overheating and damage to the instrument components, a ring or U-shaped elbow should be added between the pressure point and the pressure gauge valve. When measuring the pulsating pressure at the outlet of the compressor or pump, in order to protect the pressure gauge and make the measurement accurate, a buffer or throttle can be installed in front of the pressure gauge. ； If necessary, a damping valve can be installed to increase the resistance to the pressure gauge when the pressure changes. When the measurement medium contains dust, particles or impurities, the pressure pipe should be thickened, and if necessary, a dust collector or drain valve should be installed to facilitate purging of the pressure pipe. For humid gas, a water separator should be installed. The distance between the pressure gauge and the pressure taking point should be as short as possible. In order to avoid measurement lag, the longest pressure pipe should not exceed 50 meters. If it is too long, consider using a remote pressure gauge. For media that is prone to crystallization and blockage, a union should be installed to facilitate disassembly and blowing in the future. When installing a low-pressure pressure gauge, try to avoid the impact of the static pressure caused by the liquid column on the meter measurement. For pressure measurement of key equipment, two pressure gauges can be installed separately to prevent accidents. In order to ensure the reliability of pressure measurement and production safety, in addition to regular maintenance inspections, the pressure gauge must be calibrated according to the prescribed period. The distance between the pressure gauge and the pressure taking point should be as short as possible. In order to avoid measurement lag, the longest pressure pipe should not exceed 50 meters. If it is too long, consider using a remote pressure gauge. For media that is prone to crystallization and blockage, a union should be installed to facilitate disassembly and blowing in the future.
