Analysis on the requirements and installation conditions of the process tube when the electromagnetic flowmeter is installed
1. Electromagnetic flowmeter installation requirements 1.1 General requirements a. In order to facilitate the installation, maintenance and maintenance of the electromagnetic flowmeter, sufficient space must be reserved around the flowmeter. b. Avoid the electromagnetic flowmeter being installed where the temperature changes greatly or is subject to high-temperature radiation from the equipment C. The flowmeter should be installed indoors. If it is installed outdoors, avoid direct sunlight. If necessary, install sun protection devices. d. Avoid installing the flowmeter in an environment containing corrosive gases. Locations with vibration sources and strong magnetic fields 1.2 Process tube requirements a. The inner diameter of the upstream and downstream process tubes and the inner diameter of the flow meter should meet: 0.98DN≤D≤1.05DN (DN: flowmeter inner diameter; D: process tube inner diameter) b. The process pipe and the flow meter need to be concentric, and the coaxial deviation should not be greater than 0.05DN1.3.
